Variable displacement compressor with cylinder deactivation technology

Abstract

The invention belongs to the technical field of compressors, and mainly relates to a variable displacement compressor with cylinder deactivation technology, including a multi-cylinder piston compressor. The multi-cylinder piston compressor includes a compressor shell, and the right end of the partition The integrally formed ring is provided with a plurality of piston cylinders, the piston cylinders are located on the same ring, and each of the piston cylinders is connected to the reserved chamber and is provided with three air guide pipes, which are respectively a single-cylinder air intake pipe and a single cylinder. cylinder exhaust pipe and single-cylinder variable exhaust pipe, the single-cylinder intake pipe is equipped with a first electromagnetic valve, the single-cylinder exhaust pipe is equipped with a second electromagnetic valve, and the single-cylinder variable exhaust pipe is equipped with a third electromagnetic valve. The first solenoid valve is connected with the first control switch, the second solenoid valve is connected with the second control switch, and the third solenoid valve is connected with the third control switch. Air pipe, the outside of the compressor casing is provided with a variable discharge cylinder with an opening at the right end, which can change the displacement of the compressor, and meanwhile has a relatively simple structure and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a variable-displacement compressor with cylinder deactivation technology. Background technique [0002] The compressor is an important component of the refrigeration system. It compresses the low-temperature and low-pressure refrigerant vapor from the evaporator to make it into a high-temperature and high-pressure refrigerant vapor. Except some passenger car air-conditioning compressors are driven by a special auxiliary engine, most of the car compressors are driven by the engine, and the electromagnetic clutch is used to control the compressor to work. When the refrigeration system is working, the electromagnetic clutch of the variable displacement compressor is always in the state of engagement. It can continuously and smoothly change the piston displacement within a certain range according to the cooling load and engine speed changes, so as to realize the adjustment of the...

Problems solved by technology

However, the mechanical structure of the current variable displacement compressor is relatively large and complex. Facing the increasing number of various small cars on the market, the installation space of the compressor is getting smaller and smaller, and a new technical solution needs to be proposed to realize the compressor. variable displacement
