A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. This eliminates housekeeping, environmental, safety, and compressor component failure concerns associated with current atmospheric rupture assemblies that relieve directly to the atmosphere. The environmental compressor protection assembly contains a spring set to a pre-determined pressure. Lubricant pressure in excess of this pre-determined set pressure results in spring compression and opening of a relief path. The assembly preferably remains in a full open position and must be must be manually reset to the closed position to prevent fluid flow in the system. The relief path can lead to a fluid reservoir, a container, or directly back into the compressor frame. Flow of lubricant through the relief path results in loss of flow to the lubrication system. This triggers an alarm in the no-flow system and shutdown of the compressor. The relief path remains open until an operator resets the device. A visual indicator shows an operator if the relief valve is open or closed.

A device that relieves lubricant pressure in a divider block lubrication system into a fluid reservoir, a container, or directly back into the compressor frame to which the tubing is connected. This eliminates housekeeping, environmental, safety, and compressor component failure concerns associated with current atmospheric rupture assemblies that relieve directly to the atmosphere. The environmental compressor protection assembly contains a spring set to a pre-determined pressure. Lubricant pressure in excess of this pre-determined set pressure results in spring compression and opening of a relief path. The assembly preferably remains in a full open position and must be must be manually reset to the closed position to prevent fluid flow in the system. A preferred assembly for maintaining the valve in either the open and closed position includes two balls, one of which remains trapped behind a pin during normal operation and is forced from behind the pin during an overpressure condition, the ball being prevented by the geometry of the housing from returning without manual intervention to its operating position. The relief path can lead to a fluid reservoir, a container, or directly back into the compressor frame. Flow of lubricant through the relief path results in loss of flow to the lubrication system. This triggers an alarm in the no-flow system and shutdown of the compressor. The relief path remains open until an operator resets the device. A visual indicator shows an operator if the relief valve is open or closed.
A fluid flow monitoring, evaluation, and control system providing accurate dispensing of fluids in low volume, high pressure systems. The system includes one or more fluid flow sensors mounted on positive displacement dispensing valves and a processor that receives cycle signals from the fluid flow sensors to determine fluid flow information. If the fluid flow is not within specified limits, a signal is sent to a pump control device to adjust the pump to return the fluid flow to desired level. A dispensing valve can include a display to show cycle time or other fluid flow measurement. The system can include dispensing valves having single inputs and single outputs for measuring fluid dispensed at a point of use, which measurement can be compared to measurements taken at a divider block earlier in the hydraulic path to verify that fluid sent into the path was actually dispensed.
The invention is a divider block assembly suitable for use at high fluid pressures. Applicant has found that a sufficiently deep counterbored hole allows a mounting bolt to apply the sealing pressure well below the divider block surface, which can reduce or eliminate the compressive force on the metal around the piston bore, thereby reducing or eliminating distortion of the piston bore of the divider block and providing.

A high temperature dynamic seal and methods of assembly and use. The dynamic seal is provided as a rotating seal, which includes a stationary ring and rotating ring assembly, with a seal ring that is positioned between the stationary ring member and the rotating ring assembly. One or more high temperature seals create a seal between the stationary ring member and a device in which the dynamic seal is used. Similarly one or more high temperature seals create a seal between the rotating ring assembly and a rotating shaft of the device. One or more of the high temperature seals are formed from a metallic material with various cross-sectional shapes.
Polytetrafluoroethylene (PTFE) flosses have abrasives added to the floss fiber that increase the abrasion to teeth surfaces, and thus result in a floss that provides enhanced cleaning of surfaces of teeth that face interstices between teeth. Floss fiber is formed by loading a PTFE resin with an abrasive filler. The PTFE resin and filler are processed to form a floss fiber with a surface that provide enhanced abrasion properties.
Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.

A seal device is generally provided a seal member having multiple sealing faces, a central aperture, and an outer edge. A radially inner channel of various geometries may be formed that is open to the central aperture to provide a pressure-energized seal when a pressurized fluid enters the channel. A seal retainer may be partially disposed within a radially outer groove in the radially outer edge of the seal member. The seal retainer may have a rigid core that is at least partially coated with a non-corrosive material. Secondary seals may be engaged with the seal retainer in a radially outwardly spaced relationship with the seal member. The secondary seals may be heat-resistant.

A bearing comprises a resin matrix filled with fluoropolymer, graphite, and other discrete particles of an additive material that is attached to a backing material. The specific selection and mix of fillers with the resin matrix provides the desired blend of bearing properties such as wear resistance, fatigue and erosion resistance and low friction whilst maintaining sufficient flexibility for being formed into flanged cylindrical geometries without detriment to the adherence of the lining to the backing. A method for manufacturing a bearing comprises depositing to a backing material a fluid polymer bearing material comprised of a resin matrix filled with fluoropolymer, various fillers, and discrete particles of an additive to form a continuous consolidated bearing material, and curing the lining material to bond the lining material onto the backing material.
A cycle indicator is provided for monitoring movement of a fluid control piston of a divider block for a fluid distribution system. The cycle indicator connects to the divider block in a manner that allows fluid communication between the divider block and the cycle indicator. The cycle indicator includes a spring-biased piston follower that extends into the divider block through a housing so that movement of the fluid control piston is translated to the piston follower. The piston follower extends into the divider block through an opening in the housing. The opening is not sealed allowing fluid within the divider block cylinder to flow past the piston follower and into the housing. Since there is no relative movement between the seal and any moving part such as the piston follower fluid leakage is eliminated or at least substantially reduced. An internal magnet is coupled to the piston follower and activates an external magnet that provides a visual indication of the movement of the fluid control piston.
