A variable stroke high pressure pump is disclosed. The pump uses a wobble plate design with dynamically variable tilt to provide continuous adjustment of pump stroke length and output. Dynamically variable tilt is accomplished using a linearly actuated tilt thruster rotationally coupled to the drive shaft to maintain a selected tilt of the wobble plate through the rotation of the wobble plate.

The present invention relates to an apparatus for reducing suction pulsation and a swash plate type compressor comprising same. The apparatus for reducing suction pulsation, which is installed in a swash plate type compressor and can reduce suction pulsation of a refrigerant, comprises: a case formed in a hollow container shape and having a suction port with an open upper side in the height direction and discharge openings formed by opened areas in the side wall thereof; a core portion formed inside the case, between the suction port and the discharge openings so as to be movable in the height direction; a lever having a vertical portion extending upwardly, along the side wall of the case, from one end of a horizontal portion disposed in the vicinity of the bottom wall of the case and coupled to the case such that the portion where the horizontal portion and the vertical portion meet is rotatable about a horizontal axis; and an elastic means interposed between the core portion and the horizontal portion of the lever.

A wind energy to compressed fluid conversion system has a compressor to compress fluid when the wind energy exceeds a capacity limit of the generator. Instead of trimming blades to create mechanical spillage, excess energy is converted and stored, and can furnish power when the generator experiences a capacity vacancy.

A multi-stage compressor includes a compression module configured to compress a refrigerant therein through reciprocation of a plurality of pistons provided in a front housing, a rear housing coupled to the front housing to define an internal space between the front housing and the rear housing; a separation plate located between the front housing and the rear housing to separate the internal space between the front housing and the rear housing into a front space and a rear space; and a partition wall coupled to the rear housing to partition the rear space into an injection space before a refrigerant injected thereinto is primarily compressed, a primary discharge space from which the refrigerant is discharged in a primary compressed state by some of the pistons, and a secondary discharge space from which the primary compressed refrigerant is discharged.
