Abstract

The invention discloses a novel swinging rotor compressor with a low-pressure cavity in a shell. The novel swinging rotor compressor with the low-pressure cavity in the shell comprises a machine shelland a pump body; the pump body comprises an air cylinder component; a crankshaft is arranged on the air cylinder component in a sleeving manner; a motor is arranged above the crankshaft in a sleevingmanner; the pump body further comprises a swinging rotor arranged in the air cylinder component; the swinging rotor is connected to the air cylinder component through a sliding piece; the inner cavity of the air cylinder component is divided into a first compression chamber and a second compression chamber through the swinging rotor and the sliding piece; the first compression chamber is connected with an air suction silencing chamber through an air inlet channel; the second compression chamber is connected to an integrated exhaust cover component through an exhaust channel; and the exhaust cover component is connected to a shell exhaust pipe through an inner exhaust coil pipe. The compressor is low in vibration, low in noise, high in refrigeration amount, and excellent in starting performance.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a novel swing rotor compressor with a low-pressure chamber inside the casing. Background technique [0002] The compressor is a driven fluid machine that lifts low-pressure gas into high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. [0003] The various components on the hermetic rotary compressor are usually in rigid contact, including the suction and discharge pipe fittings, various pipe joints, etc. are made of metal materials, as the service life of the compressor increases or it works at full load for a long time, it will cause The compressor produces violent vibrations and the...
