A positive displacement device that converts energy, namely positive displacement compressors that rotate in a single rotational direction to displace working fluid contained in operating chambers. The device described herein is particularity advantageous for the ability to achieve high compression ratios in combination with high discharge pressure and high volumetric throughput in a single stage.

Disclosed are a hydrostatic pressure support and a spherical pump having the same. The hydrostatic pressure support is arranged between each of two parallel sides of a slipper and a sliding groove, and includes a first liquid flow channel, a second liquid flow channel, and a pressure-bearing groove. An inlet of the first liquid flow channel is communicated with one of two working chambers of the spherical pump, and an inlet of the second liquid flow channel is communicated with the other of the two working chambers. An outlet of the first liquid flow channel and an outlet the second liquid flow channel are respectively communicated with the pressure-bearing grooves provided on the two parallel sides of the slipper.

An anti-locking mechanism of a spherical compressor rotor, an anti-locking power mechanism of a spherical compressor, and a spherical compressor. A pin boss is fixedly arranged on a turntable shaft, and guide pins are movably connected with a guide sleeve. A concave slideway is arranged in a cylinder block spherical surface or a cylinder lower spherical surface, and is distributed along a sliding track of the guide sleeve on the corresponding cylinder block spherical surface or cylinder lower spherical surface in a rotation process of a turntable. A main shaft rotates and drives the turntable. When the turntable rotates to a position at which a turntable axis and a piston axis are superposed, the turntable can continue to rotate around the turntable axis by means of torque obtained by the guide pin from the concave slideway, and thus a problem of a dead point of movement of a spherical compressor rotor is solved. Because the concave slideway is arranged outside a spherical working cylinder of a spherical compressor, the sealing effect is good.

A displacement compressor system for the refrigerant R718 includes a compressor machine, an evaporator, and a condenser. The open compressor machine is designed as a spindle compressor in the form of a double-shaft rotation displacement compressor for displacing and compressing gaseous conveying media. The displacement compressor has a spindle rotor pair which is arranged in a compressor housing and is designed with an electronic motor pair spindle rotor synchronization function. The compressor machine is arranged between the evaporator and the condenser.
