A swing piston compressor

Abstract

A swing type piston compressor, including a frame, a cylinder, a piston rod and a cylinder valve are installed through the frame, one end of the piston rod is inserted into the volume chamber of the cylinder as a piston, and the other end is protruded from the frame and is arranged for connecting the crank The crankshaft is provided with a through groove on the frame to provide a swinging space for the piston rod; the crank drives the piston rod to swing relative to the frame and the piston end face of the piston rod reciprocates relative to the cylinder; the cylinder is rigidly connected to the pendulum so that When the cylinder swings, the swing column swings periodically in the same plane. The top column on the swing column slides in the chute of the cylinder valve, and then drives the cylinder valve to rotate in one direction; the cylinder surface of the cylinder valve is provided with suction and exhaust channels. , when the suction channel and exhaust channel of the cylinder valve are respectively rotated to communicate with the volume cavity and the air flow channel of the frame, the compressor will perform the process of suction and exhaust respectively, thereby realizing continuous and periodic operation of the compressor. The invention has the advantages of simple structure, small volume, few wearing parts and flexible and convenient use.

Description

technical field [0001] The invention belongs to the field of compressors, and in particular relates to a swing type piston compressor. Background technique [0002] The basic structure of the oscillating piston compressor is the crank rocker mechanism. This oscillating piston compressor, although the working process is similar to the reciprocating piston compressor, has a different structure. It relies on the rotation of the crank to drive the piston to oscillate around the center line of the cylinder in the cylinder to change the cylinder volume, thereby achieving suction, Compression and exhaust process. [0003] The traditional oscillating piston compressor relies on the side of the piston to compress the gas. For example, Chinese patent document CN2621232Y discloses a water-cooled non-lubricating oscillating compressor, which includes a two-stage cylinder, a rotor and a valve table. The first-stage cylinder forms two-stage compression, the rotor placed in the cylinder ...
