摘要： An end cap assembly for a reciprocating air motor comprises a pilot valve and an end cap body. The pilot has a valve stem. The end cap body comprises a central bore for receiving an air motor rod, a valve bore in which the pilot valve is disposed such that the valve stem extends through the end cap body, and an air port extending through the end cap body. The air port has a contour to direct air toward the valve stem.

摘要： An enclosed hose reel 10 consists of a spool 12 and two enclosure halves 14 comprising the frame 16. The power spring 18 is contained in the spool 12. Tension on the power spring 18 is transmitted to the frame 16 via a shaft 20 with a spring 30 loaded ratchet 22. The ratchet mechanism 24 engages the frame 16 via protrusions 26 that fit into cutouts 28 within the enclosure 14. The protrusions 26 and cutouts 28 are designed so that a clockwise rotation is allowed to increase the tension of the power spring 18.

摘要： An air valving system for a reciprocating piston pump (5) which uses piston (10) actuated poppet assemblies (40) to control the main air valve (16) shift. The valve exhaust is vented (50) directly to atmosphere rather than through the main exhaust to ensure reliability. A ramped detent (32) prevents the air valve (16) from centering.

摘要： An oval gear set 46 for use in a flow meter 28 comprises first and second gears (46A, 46B) that are identical to each other and that are configured to engage at a fixed center-to-center distance CD such that the first and second gears (46A, 46B) mesh at all angular positions. Each gear of the oval gear set 46 comprises a hub and a plurality of gear teeth 95. The hub comprises an oval body (99A, 99B) having a major axis and a minor axis extending through a center (100A, 100B) of the hub, and a root profile RP wall circumscribing the major and minor axes. The plurality of gear teeth 95 extend from the root profile RP wall. Each of the gear teeth 95 has a pair of contact surfaces with circular involute curve profiles (IC1, IC2).

摘要： A reciprocating pump comprises a cylinder, an inlet check valve, a piston, an outlet check valve and a purge circuit. The cylinder has a first end and a second end. The inlet check valve is disposed proximate a first end of the cylinder. The piston is disposed within the cylinder between the inlet check valve and the second end. The outlet check valve is disposed within the piston. The purge circuit extends across the inlet check valve and the outlet check valve to fluidly couple the first end and the second end.
