Abstract: The present disclosure provides a rotary device and a rotary system, to which a press-actuated gate valve mechanism is applied. In the rotary device and the rotary system, a pressure fluid chamber is disposed on an outside of a gate valve groove so that an action of a gate valve is controlled by means of a fluid pressure. Based on the rotary device and the rotary system, the present disclosure also provides a fluid motor, a compressor, a pump and a compressor corresponding to the rotary device and the rotary system.

Abstract: A rotating device includes a cylinder body, a front end cover, a rear end cover, a main shaft, an eccentric rotor assembly and an isolation mechanism. The eccentric rotor assembly includes an eccentric shaft, a rolling piston wheel and at least one rolling bearing. In the rotating device, the eccentric shaft is isolated from the rolling piston wheel by the rolling bearing and the two are rotated, and the cylinder body is reliably sealed by an elastic pre-tightening force. Further provided are a rotor compressor using the rotating device, and a fluid motor. A rotating valve body and a rotating valve body reset mechanism in the rotating device are also improved.

Abstract: A planetary rotary type rotation device comprises a stator, a rotor, and a center sun wheel drum (10). The stator includes a hollow cylinder block (1) having a cylinder. The rotor includes a main shaft (3), planetary piston wheel fixation flanges (9), and a planetary piston wheel (8). The two planetary piston wheel fixation flanges (9) are symmetrically fixed to the main shaft (3). The center sun wheel drum (10) is disposed between the two planetary piston wheel fixation flanges (9) and fitted over the main shaft (3). An annular piston space (19) is formed between an outer circular surface of the center sun wheel drum (10) and a cylinder wall of the cylinder of the cylinder block (1). The planetary piston wheel (8) is a cylindrical roller. The cylindrical roller is disposed in the annular piston space (19) in a rolling manner. Both ends of the cylindrical roller are fixed to the planetary piston wheel fixation flanges (9).

Abstract: A gas separating device includes a body defining a cylindrical inner chamber having a first and second ends; an intake and agitation fan disposed at the first end and drawing external gas into the inner chamber and agitates the external gas to form a first vortex traveling towards the second end; a hot gas stream discharge port located at or adjacent to an edge of the second end to discharge a part of gas of the first vortex; a vortex return device located at the second end to return the remaining gas of the first vortex not discharged from the hot gas stream discharge port, forming a second vortex traveling towards the first end through a cyclone core of the first vortex; and a cold gas stream discharge port located at a radial center of the first end or located adjacent to and around the radial center.

Abstract: A vortex type cold and hot gas separating device (100) includes a body (110) having a cylindrical inner wall surface (111), the inner wall surface (111) defining a cylindrical inner chamber (112) having a first end (113) and a second end (114); an intake and agitation fan device (120) attached to the body (110) at the first end (113) which sucks external gas into the cylindrical inner chamber (112) and agitates the external gas to form a first vortex traveling towards the second end (114); a hot gas stream discharge port (130) located at or adjacent to an edge of the second end (114) to discharge a part of gas of the first vortex traveling to the hot gas stream discharge port (130) out of the cylindrical inner chamber (112); a vortex return device (140) located at the second end (114) to return the remaining gas of the first vortex which is not discharged from the hot gas stream discharge port (130), thereby forming a second vortex traveling towards the first end (113) of the cylindrical inner chamber (112) t
