A clutch and a compressor including the same, and may include a hub fastened to a rotary shaft of a compressor and rotatable with the rotary shaft in a state where its position has been fixed, a disk fastened to the hub and rotatable with the hub, a pulley rotated by receiving power from a driving source of the compressor, an elastic member fastening the hub and the disk, fastening the hub and the disk so that the disk approaches or is away from the pulley based on the hub, a field coil assembly magnetized when power is applied to contact or space the disk and the pulley, an attenuation member interposed between the elastic member and the disk, thereby reducing the noise and vibration due to the contact and spacing between the disk and the pulley by the elastic member and the attenuation member.

A compressor that includes a casing, a compression mechanism provided inside the casing to compress a refrigerant, a rotary shaft transmitting a rotational force to the compression mechanism from a drive source provided outside the casing, a clutch connecting the drive source and the rotary shaft by a magnetic force generated when electric power is applied to the clutch and disconnecting the drive source and the rotary shaft by losing the magnetic force when the electric power applied thereto is cut off, and a rotation measurement means for receiving the magnetic force from the clutch to measure a change in magnetic flux according to the rotation of the rotary shaft and measure a rotational speed of the rotary shaft. Thus, it is possible to measure the rotational speed of the rotary shaft without including a permanent magnet.

The two-way wobble plate compressor of the present invention may significantly reduce friction loss.

The drive unit has an effect of maintaining controllability and preventing a hunting problem caused under low flow conditions since it includes a friction ring module.

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 pressurized fluid supply apparatus and method of supplying pressurized fluid is provided. The pressurized fluid supply apparatus includes a housing configured to rotate about an axis, at least one fluid pump coupled to the housing and configured to pressurize a fluid therein, and at least one movable element disposed within the housing. The at least one movable element is configured to move within the housing when the housing rotates about the axis, which causes the at least one movable element to be in periodic driving engagement with the at least one fluid pump to cause the fluid to be pressurized.

A cryogenic pump for pumping cryogenic fluid is provided. The pump includes a pump assembly adapted for exposure to cryogenic fluid that includes a plurality of pumping elements disposed about a pump axis. A drive assembly drives the pumping elements to pump cryogenic fluid. A plurality of actuating elements are arranged circumferentially about the pump axis, each actuating element operatively interconnecting the drive assembly with a respective one of the pumping elements. Each actuating element includes a first portion disposed a first radial distance from the pump axis and a second portion disposed a second radial distance from the pump axis with the first radial distance being less than the second radial distance at ambient temperature.

Disclosed herein is a double-headed swash type compressor, and a distance between an outer peripheral surface of a shaft (20) and an inner peripheral surface of a shaft bore (11) is greater than a distance between the outer peripheral surface of the shaft (20) and an inner peripheral surface of a journal bearing (30).
