Embodiment Construction

[0018] The cylinder (1) rotates counterclockwise under the drive of the drive shaft (4), and the piston (3) reciprocates radially along the cylinder (1) under the control of the centrifugal action and the offset bearing (2). Figure 1B Among them, the suction side pistons (3a, 3b, 3c, 3d) are in the suction state; the compression and exhaust side pistons (3e, 3f, 3g, 3h) are in the compression and exhaust state.

[0019] Figure 1B Among them, a pressure chamber (5b) is arranged on the compression adjustment disc (5), and the compression adjustment disc (5) is also controlled by the torsion spring (10). The air pressure in the pressure chamber (5b) and the torsion spring (10) provide the clockwise torque of the compression adjustment disc (5); the pressure at the exhaust port (5a) of the compression adjustment disc provides the counterclockwise torque of the compression adjustment disc (5); The front-stage compression cylinder chamber (where 3e is located) is connected, and t...

Abstract

The invention discloses a rotary piston type air compressor capable of regulating the compression ratio automatically. A plurality of cylinder chambers and pistons are uniformly and radially distributed on a cylindrical cylinder in the radial direction; the axis of the cylindrical cylinder is connected together with a drive shaft; a bearing is offset outside the cylindrical cylinder. The pistons rotate with the cylinder and have reciprocating movement as well along the radial direction of the cylinder body so as to finish inhaling, compression and exhausting. An inhaling port and an exhausting port are both in the axis side of the cylinder; a compression regulating disc is arranged in the axis of the cylinder for automatically regulating the air compression ratio during exhausting, so that the pressure in a compression chamber is equal to that at the exhausting side during exhausting. When the cylinder rotates, the inhaling, compression and exhausting are continuous; the load is stable; the needed driving moment is reduced; moreover, no inhaling and exhausting valves are arranged, the theoretical volumetric efficiency is 100%, and no eccentric rotation is caused, so the compression efficiency is improved and vibration caused in operation is reduced. The rotary piston type air compressor disclosed by the invention is used for a closed motor driven compressor and an external driven compressor.

Description

Technical field [0001] The invention relates to an air compression device. [0002] The invention relates to a closed motor-driven air compressor. [0003] The invention relates to a driving external air compressor. Background technique [0004] At present, air compressors include rotor type, scroll type, plunger type and so on. Such compressors have disadvantages such as unstable load, low compression efficiency, large vibration, and large required driving torque. Invention content: [0005] The compressor of the invention overcomes the shortcomings of the existing air compressors such as unstable load, low compression efficiency, large vibration, and large required driving torque.
