Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1-8 shown.

[0022] A swash plate type variable displacement compressor, including a main shaft 1, the input power of the engine is transmitted to the cradle 2 rigidly connected to the main shaft 1 through the rotating main shaft 1, and the cradle 2 rotates together through the sliding slope 4 and the drive fork 5. The power is transmitted to the swash plate 3. The swash plate 3 can slide on the rotating main shaft 1 and rotate synchronously with the main shaft 1. When sliding, the swash plate 3 is under the action of the control valve and the related air channel structure (the control valve and the related air channel structure The design is the same as that of the existing swash plate compressor) The inclination angle relative to the main shaft 1 can change, the swash plate 3 converts the direction of motion through the sliding...

Abstract

A swash plate type variable displacement compressor, including a main shaft for power input, a wobble plate fixed on the main shaft to rotate with the main shaft, and a coated swash plate sliding on the wobble plate, the swash plate relative to the rotating main shaft The inclination angle can be changed to convert the rotary motion into the reciprocating motion of the piston with variable stroke, and the spring installed on the main shaft to compress the swash plate ensures the compressor has stable low-displacement performance. The wobble plate and the swash plate of the present invention adopt curved surface compensation, which can ensure the constant gap, greatly improve the running stability and reduce the noise.

Description

technical field [0001] The invention relates to a compressor technology, in particular to a swash plate compressor technology, in particular to a swash plate variable displacement compressor. Background technique [0002] Usually, the variable mechanism of the variable displacement swash plate compressor adopts a hinged structure. Since the connecting rod mechanism cannot guarantee the constant dead point gap of the piston, the dead point gap of the compressor changes with the displacement, resulting in noise and other problems. The surface of the swash plate is coated with wear-resistant coating after spraying copper alloy with supersonic flame spraying technology (HOFV). Basic-level methods cannot achieve excellent cost performance. Contents of the invention [0003] The purpose of the present invention is to design a swash plate variable displacement compressor that can achieve variable displacement smoothly and has stable performance, aiming at the problems of high no...
