A capacity control valve includes a valve housing provided with a discharge port, suction ports, and a control port and a primary valve including a primary valve seat and a primary valve body driven by a solenoid, the primary valve being configured to open and close a communication between the discharge port and the control port in accordance with a movement of the primary valve body. The capacity control valve further includes a differential CS valve which is openable and closable by a pressure difference between the control pressure Pc and the suction pressure Ps and an electromagnetic CS valve that is openable and closable so as to close the control port and the suction port in a non-energized state of the solenoid 80 in accordance with the movement of the primary valve body.

A capacity control valve includes a CS valve which opens and closes a communication between the control fluid and the suction fluid by the movement of rods and an urging member configured to urge the primary valve body and the rods in opposite directions and the primary valve body and the rods are disposed so as to be relatively movable in an axial direction.

An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.

A high-pressure compressor and a system with a high-pressure compressor are described. I one example, the high-pressure compressor has a housing that surrounds at least one compressor chamber and a media chamber, wherein the compressor chamber and the media chamber are separated from one another in the housing via a diaphragm. The housing has at least one first connection, which opens into the media chamber and via which a medium can be introduced into and/or discharged from the media chamber. The housing has at least one second connection, which opens into the compressor chamber and via which a gas or gas mixture can be introduced and/or discharged. The diaphragm comprises a polymer -based material and is deformable to compress a gas or gas mixture that can be introduced into the compressor chamber by introducing a medium into the media chamber.

The carbon free compressor pump system is a device that utilizes several pistons in a hydraulic or power press manner to compress gas or pump fluids. The device utilizes mechanical advantage of a pulley on the upstroke and uses a clutch device to utilize the gravitational force on the downstroke. In order to accomplish this the device includes a base that allows the compression process to take place and ensure there is only vertical movement. Further, the weight block ensures the system can utilize gravitational force on the downstroke. Further, the plurality of outtakes allows for the gas or fluids to flow out of the system once compressed or pumped. Furthermore, the conical tank takes the compressed gas or pumped fluid and further compresses the gas, increasing the pressure without moving parts. Thus, the device operates on carbon free electricity to compress gas and pump fluids.

A capacity control valve includes a valve housing provided with a discharge port, suction ports, a control port and a primary valve driven by a solenoid. The capacity control valve further includes a differential CS valve which includes a differential CS valve body disposed so as to be relatively movable in an axial direction with respect to the primary valve bodies. The differential CS valve body divides a control pressure chamber into a discharge side control chamber communicating with the first control port and a suction side control chamber communicating with the second control port in the axial direction and operates the differential CS valve body by a differential pressure between the discharge side control chamber and the suction side control chamber so as to open the second control port and the suction port.
