Abstract: An inflating connector includes a base, a pressure valve, a gas bottle connecting seat, and a throttling valve. The base has an assembling passageway, a first gas passageway communicating with the assembling passageway, and a second gas passageway communicating with the assembling passageway, a gas nozzle to be connected with the second gas passageway. The pressure valve has an elastic member and a piston, which are accommodated in the first gas passageway. The elastic member acts on the piston to make it close up the first gas passageway. The gas bottle is disposed on a side of the assembling passageway, and has a gas inlet passageway for being connected with a gas bottle and a gas outlet passageway communicating with the gas inlet passageway. The throttling valve has an operation unit and a throttling member capable of being driven by the operation unit to displace along the gas outlet passageway.

Abstract: A flow control device includes a housing with an inlet and an outlet and a flow conduit disposed in the housing. The inlet, the flow conduit, and the outlet define a flow passage. A valve seat is disposed in the housing downstream of the inlet, and a shuttle is movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage. A sealed chamber is defined between the housing and the flow conduit. A port coupled with a source of pressurized fluid communicates with the sealed chamber, where the shuttle is displaceable between the closed position and the open position based on a pressure in the sealed chamber. The threshold water pressure for displacing the flow conduit may be adjustable by modifying the pressure in the sealed chamber.

Abstract: A valve body has a piston that slides within the body through four successive positions. The piston has a head, and an upper and lower skirt, with a port in the upper skirt. In the first position, a bias force urges the piston to the first of four positions, in which the piston port is closed. In a second position, the piston port aligns with a low pressure port in the valve body, when a low pressure supply of water is connected. In a third position, greater pressure again closes the piston port. In a fourth position, at a still greater pressure, the piston port aligns with a high pressure port in the valve body. The bias force or a location of the piston port can be varied for valves along a supply line, whereby varying supply pressure opens different valves, thereby enabling addressing of valves according to supply pressure.

Abstract: A variable displacement compressor for an air conditioning system includes a suction throttle valve. The suction throttle valve includes a housing with a cavity formed therein. A first piston reciprocatingly disposed in the cavity is configured to cause a variable restriction of a flow of refrigerant through a suction inlet formed in the housing. The suction inlet provides fluid communication between a suction port and the cavity formed in the housing. The refrigerant flows through the suction port in a direction that is not parallel to a direction the piston reciprocates within the cavity. The suction throttle valve is configured to increase the restriction in the suction inlet when a crankcase pressure associated with the variable displacement compression is increased relative to an external suction pressure of the refrigerant entering the suction throttle valve.

Abstract: A pressure relief valve includes a housing including an inlet chamber adapted to be in communication with an outlet of a pump and an outlet chamber adapted to be in communication with a pump inlet. The housing includes a bore having a first end in communication with the inlet chamber and a main spill aperture in communication with the bore and the outlet chamber. A piston includes an orifice and an axially spaced apart aperture. The piston is axially moveable within the bore between a first position whereat the piston seals the inlet chamber from the outlet chamber, a second position whereat the inlet and outlet chambers are in fluid communication with one another via only the orifice, and a third position whereat the inlet and outlet chambers are in fluid communication with one another via the orifice and the aperture. A spring biases the piston toward the first position.

Abstract: A speed controller valve system for regulating an opening speed and a closing speed of a pressure reducing valve includes a first inlet couplable to a main valve inlet of a pressure reducing valve. An outlet is couplable to a power chamber of the pressure reducing valve to control a flow of fluid between the outlet and the power chamber to control an opening and/or a closing of the pressure reducing valve. An interior chamber connects the first inlet and the outlet. The chamber receives a resilient member connected to a tapered valve poppet received in the first inlet and moveable in response to a flow of fluid at a pre-set pressure from the main valve inlet to the first inlet. The poppet is located in the chamber and the resilient member includes a resiliency to regulate an amount of movement of the poppet at the pre-set pressure to regulate a flow between the first inlet and the power chamber of the pressure reducing valve.

Abstract: A poppet scavenger valve includes multiple cages for multiple poppets, permitting better control of the spacing of the assembly, facilitating maintenance and permitting better fluid flow through the cage structure. A spacer or lift plate may be positioned between the cage and the seat for defining a flow control device for accurately setting and controlling the valve flow. Each cage component is mounted on the lift plate and is trapped between the plate and the seat. Alignment pins are provided to assure proper alignment between the cylinders and the mated counter bores in the cages. The stroke, or valve flow, can be controlled by adjusting the height of the lift plate, without any alteration to or modification of the cage. Multiple cage configurations are possible, including cages for supporting any array of poppets from a grid to a longitudinal assembly. Each cage is adapted for supporting any multiple of poppets, including single poppet cage systems where applicable. Each of the plurality of cages in the valve system may be customized to provide clearance for external components and for other uses, as necessary.
