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 piston type compressor has a main housing including a cylinder housing. The cylinder housing has a central bore for receiving a shaft therein through a first surface thereof and a plurality of bores configured for receiving a plurality of pistons therein through the first surface thereof. An inlet is configured for conveying a primary fluid to the plurality of bores. An outlet is configured for conveying the primary fluid from the plurality of bores. A plurality of passages is separate from the inlet and the outlet. Each of the plurality of passages is formed in the main housing and is configured for conveying a supplemental fluid to one of the plurality of bores.

A compressor includes a cylinder housing having a number of pistons, a control chamber communicating with piston casings, a suction chamber and a discharge chamber communicating with the piston casings, a control valve includes a receptacle engaged in the cylinder housing, a valve member engaged in the receptacle for controlling the pressurized air to flow from the discharge chamber into the control chamber of the cylinder housing, and a valve element for controlling a bypass of the pressurized air through the receptacle. A bellow device is connected to actuate the sliding member internally, and a sliding member is slidably engaged in the control space of the receptacle, and to operate the valve element externally with a solenoid device.

Variable displacement compressor 100 has second control valve 350 for adjusting the opening degree of pressure release passage 146. Second control valve 350 includes partition member 351, which partitions valve chamber 351c and back pressure chamber 351d, and has side wall 351a surrounding valve portion 352b of spool 352, and end wall 351b connected to one end side of side wall 351a and through which shaft portion 352b of spool 352 penetrates. Furthermore, in second control valve 350, end surface 351a1 opposite to the end wall of the side wall of partition member 351 abuts on the wall surface opposite to the back pressure chamber of the valve chamber 351c. When the valve portion 352b of spool 352 abuts on the wall surface, pressure receiving portion 352a of spool 352 abuts on end wall 351b.

A swash plate type variable displacement compressor includes a housing having therein a suction chamber, a discharge chamber, a swash plate chamber and a cylinder bore. The compressor further includes a drive shaft and a swash plate that is mounted on the drive shaft for rotation therewith. The compressor further includes a link mechanism, a piston, a conversion mechanism, an actuator and a control mechanism. The actuator includes a partitioning body, a moving body and a pressure control chamber formed between the partitioning body and the moving body into which a refrigerant is introduced from the discharge chamber for moving the moving body. A connecting member and a connecting unit are disposed on radially opposite side of the drive shaft. The compressor further has an urging member that urges the moving body that reduces the inclination angle of the swash plate.

A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. Each of the coupling portions includes an outer portion and an inner portion. A direction orthogonal to both of an opposing direction of the inner portion and the outer portion and the axial direction of the double-headed piston is referred to as a widthwise direction. The neck is larger in the widthwise direction than in the opposing direction so that the neck is deformable in the opposing direction. Each of the two coupling portions has a width that is less than or equal to a width of the neck. The inner portion includes a narrow portion. The narrow portion is at least partially located closer to the head than the shoe holder in the inner portion. The two coupling portions are deformable in the widthwise direction when the swash plate applies load to the double-headed piston.

A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. Each of the coupling portions includes an outer portion and an inner portion. A direction orthogonal to both of an opposing direction of the inner portion and the outer portion and the axial direction of the double-headed piston is referred to as a widthwise direction. The inner portion includes a narrow portion and a wide portion. The wide portion projects out of the narrow portion in the widthwise direction and has a larger width than the narrow portion. An outer surface of the wide portion is slidable on a wall surface of the corresponding cylinder bore when the double-headed piston reciprocates in the cylinder bores.

A double-headed piston type swash plate compressor includes a rotation shaft, a housing, a swash plate, two cylinder bores, a double-headed piston, and two shoes. The double-headed piston includes two shoe holders, a neck, two heads, and two coupling portions. At least one of the two coupling portions includes a load receiving portion. The load receiving portion is configured to receive bending load that is applied from the swash plate to the double-headed piston and acts toward an inner side in the radial direction. The load receiving portion is separated from the wall surface of the cylinder bore when load applied to the double-headed piston is less than a specific threshold value. The load receiving portion abuts against the inner wall of the cylinder bore and receives the bending load when the load applied to the double-headed piston is greater than the specific threshold value.

A variable displacement swash plate type compressor includes a rotary shaft, a swash plate, and an actuator, which changes the inclination angle of the swash plate. The actuator includes a partition body and a movable body, which moves in a direction along the rotational axis of the rotary shaft. The movable body includes a guide surface, which changes the inclination angle of the swash plate, and a sliding portion, which slides on the rotary shaft or on the partition body. When viewed from a direction that is perpendicular to the direction in which the rotational axis of the rotary shaft extends and perpendicular to a first direction, the guide surface is configured such that a perpendicular line or a normal line to the guide surface intersects with the rotational axis of the rotary shaft in a zone surrounded by the sliding portion.
