Abstract: A capacity control valve includes a main valve that opens and closes communication between a discharge port and a control port formed in a valve housing by movement of a rod driven by a solenoid, a CS communication passage providing communication between a control fluid supply chamber formed in the valve housing and a suction port, and an on-off valve formed by a communication passage forming member having an annular valve seat in an outer periphery of the CS communication passage and an on-off valve element biased in the valve closing direction with respect to the valve seat.

Abstract: A main valve throttle (53) of a main valve (43) is configured by a lateral hole (53A) communicating an inlet side flow passage (25) and an outlet side flow passage (27) through the inside of the main valve (43) and a groove portion (53C) communicating the inlet side flow passage (25) and the outlet side flow passage (27) via an outer peripheral portion of the main valve (43). The groove portion (53C) is located such that a hydraulic fluid spurting from the groove portion (53C) changes the direction of a flow of a hydraulic fluid spurting from the lateral hole (53A). In this case, the direction of a flow of a hydraulic fluid F2 spurting from the lateral hole (53A) can be changed to approach the direction parallel to the center axis of the main valve (43) by a hydraulic fluid F1 spurting from the groove portion (53C).

Abstract: A self-energizing valve includes a valve body defining an inner chamber having an inlet and an outlet. A valve head within the inner chamber is moveable between a first position and a second position. A valve seal in fluid communication with the inlet has a sealing surface with a sealing member between the valve head and the valve seal. The sealing member is movable between a closed position where the sealing member engages with the sealing surface and an open position where the sealing member disengages from the sealing surface to allow flow through the inlet into the inner chamber. A cam is coupled to the valve head. Rotation of the cam causes movement of the valve head between the first position and the second position to move the valve head to the first position to hold the sealing member in the closed position.

Abstract: An indexing valve for a regenerative thermal oxidizer (RTO). A valve housing includes a diverter assembly further comprising: a pipe shaft, the pipe shaft disposed through the valve housing; a diverter blade subassembly connected to the pipe shaft between the pipe shaft ends for rotating within the valve housing, the rotation of which is supported by a bearing assembly at the base; the diverter blade subassembly further comprising a pair of opposing diverter plates, each of the diverter plates curved, wherein a large-volume inlet plenum is defined between the diverter plates for receiving fluid flow from one of the ports.

Abstract: A combination plumbing trap and vent assembly for retrofitting existing sink installations is disclosed. The assembly includes a J-bend pipe with an inlet for attachment to a sink and an outlet, a T-pipe with an inlet arm connected to the J-bend outlet, a valve arm, and an outlet arm for connection to a drain, and an air admittance valve (AAV) attached to the valve arm.
