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.

The pump has a casing accommodating a piston and a driving part. The casing has a first casing member having a driving part retaining portion retaining the driving part, a second casing member fixedly stacked on the first casing member in the reciprocating direction of the piston, and a cylindrical pump chamber peripheral wall member disposed around a head of the piston. The second casing member has an end wall portion extending in a transverse direction substantially perpendicular to the reciprocating direction. A pump chamber, a delivery chamber, and a buffer chamber are defined between the first casing member and the end wall portion of the second casing member. The pump chamber, the delivery chamber, and the buffer chamber are disposed side-by-side in the transverse direction.

A piston of an air compressor contains at least one fixing bolt configured to fix a plane of a top of a head of the piston in at least one air stop sheet. A respective one air stop sheet includes at least one bending section, an acting zone configured to close at least one air orifice of the head. The head has at least one receiving groove configured to receive a spring, the spring abuts against the respective one air stop sheet, and the acting zone of the respective one air stop sheet backing a top of a cylinder turns on relative to the plane of the head at the open angle θ, thus producing the air flowing space. The air flowing space is in communication with the at least one air orifice so that a pressure of the cylinder balances with atmosphere.

A fluid pump for pumping a fluid. One or more piston-cylinder arrangements each include a respective cylinder portion, a respective head portion and a respective piston portion together defining a respective pumping chamber. One or more connecting arrangements connect a crank member to the one or more piston-cylinder arrangements to drive the respective piston portion of each of the one or more piston-cylinder arrangements. A housing and the respective piston portion of each of the one or more piston-cylinder arrangements together house the crank member in an interior. The interior is sealed to capture blow-by. A transmission is arranged to transmit power, for rotating the crank member, into the housing magnetically, electrically or both.

A compressor comprises a first cylinder for compressing a fluid and a second cylinder for driving a piston in the first cylinder. The first cylinder comprises a chamber configured to receive the fluid. The piston is reciprocally movable in the chamber for compressing the fluid. The chamber comprises four ports at the first end including two inlet ports and two outlet ports with a check valve is connected to each port. Each of the four ports is slanted such that the plurality of check valves and inlet and outlet conduits are spaced apart from the second cylinder. The compressor further comprises an inlet conduit to supply the fluid from a fluid source to the chamber through the inlet ports and an outlet conduit for receiving fluid from the chamber through the outlet ports.

A piston is described for the compression of a pneumatic fluid in a compression chamber of a cylinder comprising: a cylindrically shaped piston body, adapted to be arranged slidably within said cylinder, and having a side wall and a top wall; along a circumferential perimeter of said side wall of the piston body a seat being defined; and a sealing assembly accommodated in said seat, and adapted to ensure the fluid-tightness along said circumferential perimeter; the sealing assembly comprising a plurality of sealing elements, having shapes complementary to one another, and configured so that the wear of a sealing element along said circumferential perimeter corresponds to a sliding in the radially outer direction of the adjacent sealing element.
