An industrial gas spring with a hydraulic accumulator includes a piston rod of the received in a hydraulic chamber connected to a gas over hydraulic fluid accumulator chamber in which a compressed gas determines the force required to yieldably move the piston rod from its extended position to its retracted position. On a return stroke of the piston rod as it approaches its fully extended position, a hydraulic damper chamber in the hydraulic cylinder may reduce the velocity of the returning piston rod. The damper chamber may return a hydraulic fluid through an orifice to the hydraulic cylinder chamber. The orifice may provide a varying restriction to vary and control the velocity or rate at which the piston rod returns to its fully extended position.

A delay return gas spring including a piston at least partially received in a cylinder for reciprocation between extended and compressed positions over a cycle including a compression stroke and a return stroke. A seal disposed between the cylinder and the piston separates a primary chamber on one side of the seal from a secondary chamber on another side of the seal during a portion of the cycle. A passage communicates with the secondary chamber and with the primary chamber. The seal is relatively movable between an open position permitting free flow of gas through the passage to a closed position at least partially restricting gas flow through the passage so as to permit gas in the secondary chamber to be compressed in response to movement of the piston toward its extended position, thereby reducing a net return force on the piston and decreasing a velocity of the piston.
An apparatus may have a cylinder including a piston rod and a chamber in which a working fluid is received to resist movement of the piston rod into the chamber, and an accumulator having a first chamber in communication with the cylinder chamber to receive fluid from the cylinder chamber upon movement of the piston rod into the cylinder chamber. The apparatus may also have a pressure controller having a fluid chamber where some of the working fluid may be received and an actuator operable to increase the volume of the fluid chamber when the piston rod is retracted into the cylinder chamber to increase the total volume in which the working fluid may be received, wherein the increased volume of the fluid chamber may accommodate fluid movement in the assembly not caused by movement of the piston rod.

The seal generally is provided between the piston rod and the casing to prevent gas leakage from the gas chamber.

A hydraulically-operated press-driven tool actuation system includes a press-driven hydraulic power device and/or a hydraulically-powered tool actuator. In the tool actuator, at least two pistons are carried by a housing, and at least one return device is carried by the housing laterally inboard of the pistons. In the power device, a pump includes a piston disposed in a pump cylinder for pressurizing hydraulic fluid therein. An accumulator is in fluid communication with the pump cylinder, and includes a piston disposed in an accumulator cylinder that houses hydraulic fluid on one side of the piston. A body supports the pump and accumulator thereon and is in fluid communication between the pump and accumulator cylinders. The body includes a pressure relief valve downstream of the pump cylinder and upstream of the accumulator cylinder, and a check valve downstream of the accumulator cylinder and upstream of the pump cylinder.
A pressure indicating device includes a case including a gas passage, and a movable indicator carried by the case. The indicator has an end in fluid communication with the gas passage and an indicator end projectable out of a portion of the case when pressure in the gas passage is at least a predetermined minimum pressure. A spring may retract the indicator when pressure in the gas passage is below the predetermined minimum pressure.
G01L 7/16 - Mesure de la pression permanente ou quasi permanente d’un fluide ou d’un matériau solide fluent par des éléments mécaniques ou hydrauliques sensibles à la pression sous forme de pistons
G01L 9/00 - Mesure de la pression permanente, ou quasi permanente d’un fluide ou d’un matériau solide fluent par des éléments électriques ou magnétiques sensibles à la pressionTransmission ou indication par des moyens électriques ou magnétiques du déplacement des éléments mécaniques sensibles à la pression, utilisés pour mesurer la pression permanente ou quasi permanente d’un fluide ou d’un matériau solide fluent
A reaction device for forming equipment includes a housing having a mount adapted to be connected to a forming die and a casing carried by the mount. A lift rod is disposed at least partially on the housing for movement relative to the house between extended and retracted positions. The lift rod has a first end disposed in the housing, a second end and a passage extending through the lift rod between its ends. An adapter is connected to the lift rod within the passage and is adapted to be coupled to a lift bar of the forming equipment. A biasing member is disposed between the lift rod and the housing to yieldably bias the lift rod to its extended position.
A reaction device for forming equipment includes a base, a reaction member movably spaced therefrom by guides, and a return gas spring carried by the base and operatively engaged to the reaction member for yieldably biasing the reaction member away from the base. The base has a return gas spring passage and guide shaft passages spaced apart therefrom. A return gas spring is received in the return gas spring passage of the base, and has a piston rod with an end arranged for contact with the reaction member. The guides include guide shafts arranged for engagement with the reaction member and disposed in guide bushings, which are received in the guide shaft passages of the base and preferably project below the base for use in locating the reaction device on the forming equipment.
