An air/gas sampling apparatus is used to retrieve, store, and ship an air/gas sample from a high-pressure air/gas source. The air/gas sampling apparatus includes a filter housing having a filter housing inlet segment and a filter housing outlet segment. The filter housing inlet segment has an inlet orifice and defines a flow restrictor passage and is removably connected to the filter housing outlet segment, defining a filter chamber at a flow restrictor passage outlet where the filter chamber holds a filter pad. As the entirety of the air/gas sample flows into the flow restrictor passage and through the filter pad to ensure the quality of the test of the air sample, the flow restrictor passage reduces the air/gas sample flowing to the filter chamber. The filtered air/gas sample is consequently delivered to and stored in a sample bag that may be shipped to a testing facility for analysis.

A screw pump (20) with field refurbishment provisions has screws (40), a base (26), and shafts (50) for the screws (40). The screws (40) have helical flights that intermesh during rotation, and extend between inner and outer ends (44 and 42). The shafts (50) extend between inner and outer ends (68 and 74), and are cantilevered from the base (26) from about the inner end (68) thereof. Each screw (40) is formed with a hollow core (80) for receiving its shaft (50) such that the screw (40) slips onto the respective shaft (50) therefor over the outer end (74) of its shaft (50). The screw pump further includes a keyless locking mechanism (56, 58, 96, or 98) intermediate each shaft (50) and screw (40), which is operative to rotationally lock the shaft (50) and screw (40) together without a key or keyway.
F01C 1/16 - Rotary-piston machines or engines of intermeshing-engagement type, i.e. with engagement of co-operating members similar to that of toothed gearing of other than internal-axis type with toothed rotary pistons with helical teeth, e.g. chevron-shaped, screw type
A bi-rotational hydraulic motor having a selectively pluggable case drain with check valves incorporated into the thrust plate allowing excess lubrication fluid to pass from the bearings into the outlet port of the motor.
A high temperature centrifugal pump includes non-linear fluid flow paths between the pump housing and seal housing to reduce fluid flow therebetween. In another aspect, the invention provides a drive shaft of variable diameter to compensate for different amounts of thermal expansion to maintain a more consistent gap profile between the drive shaft and thermal insulators or other components positioned around the drive shaft. In yet another aspect, a tube heat exchanger may be placed in fluid communication with the seal housing to re-circulate and cool the fluid therethrough.
A twin screw compressor has a working chamber bypass that is used at start-up of the compressor. This system provides pressure relief by allowing oil or other fluid to pass through it. The bypass includes a fluid passage that extends from the working chamber to the discharge port with a one way valve disposed inside the passage.
F04C 18/16 - Rotary-piston pumps specially adapted for elastic fluids of intermeshing-engagement type, i.e. with engagement of co-operating members similar to that of toothed gearing of other than internal-axis type with toothed rotary pistons with helical teeth, e.g. chevron-shaped, screw type
