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 vehicle seat in accordance with the present disclosure includes a seat bottom, a seat back, and an occupant comfort system. The occupant comfort system includes a pneumatic pump and a pneumatic bladder. The pneumatic pump provides a stream of pressurized air to the pneumatic bladder to inflate the pneumatic bladder.

A double-headed piston swash plate type compressor includes a rotary shaft, a drive force transmitting member, a tiltable swash plate, a movable body that changes the inclination angle of the swash plate, and a control pressure chamber defined by the movable body and the drive force transmitting member, which are arranged on one side with respect to the swash plate in the axial direction of the rotary shaft. The movable body includes a bottom portion, through which the rotary shaft extends, and a cylindrical portion, which extends from the bottom portion in the axial direction of the rotary shaft to surround the rotary shaft. The cylindrical portion is permitted to move in the axial direction while sliding along a part of the drive force transmitting member, so that the inclination angle of the swash plate is changed in accordance with the internal pressure of the control pressure chamber.

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 variable displacement swash compressor includes a housing, a drive shaft, a swash plate, a link mechanism, a piston, a conversion mechanism, an actuator, and a control mechanism. The swash plate is rotatable together with the drive shaft in a swash plate chamber. The conversion mechanism reciprocates the piston in a cylinder bore. The actuator is operative to change the inclination angle of the swash plate. The actuator is rotatable integrally with the drive shaft. The actuator includes a partitioning body, a movable body, and a control pressure chamber. The control mechanism changes the pressure of the control pressure chamber to move the movable body. The movable body and the link mechanism are located at opposite sides of the swash plate.

A swash plate type variable displacement compressor includes, a housing, a swash plate disposed in the housing and having therethrough an insertion hole, a rotary shaft inserted through the insertion hole of the swash plate, a plurality of pistons engaged with the swash plate, and a connecting member disposed between the rotary shaft and the swash plate and connecting the rotary shaft and the swash plate so as to change inclination angle of the swash plate relative to the rotary shaft. A pair of projections are provided in the insertion hole so as to extend toward the rotary shaft and restrict the movement of the swash plate relative to the rotary shaft. The paired projections are spaced away from each other so as not to be in contact with the rotary shaft simultaneously.

A hinge assembly for coupling a rotor assembly to a swash plate assembly in a variable displacement compressor includes a hub integrally formed with the swash plate assembly and a pair of spaced part arms coupled to the hub and extending outwardly therefrom. Each of the arms having an aperture formed in a distal end thereof. At least one support member extending from the rotor assembly and having a slot formed therein. A hinge pin is slideably received in the slot of the at least one support member and received in the aperture of each of the arms to hingedly couple the arms to the at least one support member.

A compressor including: a casing; a rotary shaft rotatably mounted in the casing; a compression mechanism configured to compress a refrigerant by operating in conjunction with the rotary shaft; a thrust plate configured to support an end surface of the rotary shaft; a chamber configured to accommodate the thrust plate; and a slit configured to guide oil to the chamber, in which a part of the slit is formed to face a contact portion between the rotary shaft and the thrust plate, such that it is possible to supply the oil between the rotary shaft and the thrust plate, thereby preventing damage to the thrust plate for supporting the rotary shaft. In addition, an inner diameter of the chamber gradually increases, and the chamber extends to an end surface of a cylinder block, such that the cylinder block may be easily extracted from a mold.

A compressor moves a fluid from an inlet to an outlet and provides a pressure differential there between due to respective pistons moving in and out of a plurality of piston chambers via a piston rod. A rotating shaft extends through a grooved end plate, and the rotating shaft is connected to either the grooved end plate or the piston rod. The grooved end plate defines an off center or eccentric groove. A bearing extends from the piston rod and fits within the groove such that when the rotational motion of the shaft rotates either the piston rod or the grooved end plate, the piston rod slides back and forth relative to the rotating shaft. Each position of the bearing within the groove determines a corresponding position of the piston rod relative to the rotating shaft. Each pair of pistons may extend from a single, continuous piston rod.

A swash plate compressor has bosses on the inner faces of the bridges of its pistons that contact the outer face of the swash plate only between the edges to eliminate wear at the edges and to thereby increase the life of the compressor.
