Abstract

The invention discloses a star-rotation type rotary device adopting a gate valve structure. The star-rotation type rotary device comprises a cylinder body and a main shaft, wherein a circular-barrel-shaped cavity is formed in the cylinder body; the main shaft is supported by cylinder body sealing end covers at the two sides of the cylinder body; a centre sun gear roller is sleeved on the main shaft; a gate valve groove is formed on the cylinder body along the centre line direction of the cylinder body; a gate valve plate is arranged in the gate valve groove; the gate valve plate is switched between a withdrawing status and an extending status; an annular piston space is formed by an outer cylindrical surface of the centre sun gear roller and an inner cylindrical surface of the cylinder body; a cylindrical planetary piston wheel is arranged in the annular piston space in a rolling manner; when the gate valve plate is in the withdrawing status, the planetary piston wheel passes through the gate valve plate; and when the gate valve plate is in the extending status, the far end of the gate valve plate contacts the outer cylindrical surface of the centre sun gear roller at the inner side surface of the annular piston space. According to the star-rotation type rotary deice adopting the gate valve structure disclosed by the invention, the difficulty of machining the cylinder body can be reduced, and the integral intensity of the cylinder body is improved.

Description

technical field [0001] The invention relates to the technical fields of engines, fluid motors, compressors and pumps in the mechanical industry, and in particular to a star-rotary rotating device using a gate valve mechanism. Background technique [0002] For the engine field, there are mainly reciprocating piston four-stroke engines, triangular rotor engines, gas turbines and so on. In the structure of hydraulic or air motor, there are mainly plunger type, vane type, gear type and turbine type, etc., which are relatively monotonous. In the traditional field of compressors and pumps, there are mainly many mechanical structures such as plunger type, vane type, gear type, screw type, crank type and scroll type. People are constantly improving and innovating while applying these mechanical structures. [0003] In the patent application (patent application number: 201010196950.8) submitted by the applicant of the present application on June 10, 2010, a spiral fluid motor or en...
