Problems solved by technology

[0009] On the other hand, the problem of the prior art is that the flow resistance of the refrigerant is generated inside the swash plate chamber by the connection mechanism formed on the swash plate and the lug plate, so that the efficiency of the compressor is reduced, and the connection mechanism passes through each support arm. To realize the fit or form it with a joint structure using pins, etc., but the fit or joint formed in this way has a complicated external shape and has too many protrusions, etc., so the flow resistance of the refrigerant is high

Abstract

The invention provides a variable capacity compressor. Wherein the lug plate is fixedly arranged on a driving shaft, and the inclined angle of the inclined disc is variable when the inclined disc is combined with the lug plate to rotate. The convex lug plate comprises a pair of convex lug arms which are arranged on one side surface of the convex lug plate at intervals in a manner of keeping a corresponding distance and are formed by protruding towards the swash plate; the swash plate comprises a single swash plate arm which is formed on the other side face of the swash plate and protrudes towards the lug plate. Wherein the single swash plate arm is formed in an arc shape, and the swash plate arm is disposed between a pair of lug arms provided at a corresponding distance from each other sothat the left and right side surfaces of the swash plate arm are close to the inside of each of the pair of lug arms, thereby forming a fitting portion. When the swash plate forms a maximum inclination angle, a fitting portion formed by close contact of the pair of lug arms and the swash plate arm forms a cylindrical shape, so that flow resistance generated at the fitting portion is minimized, andefficiency of the compressor is increased.

Description

technical field [0001] The present invention relates to a variable capacity compressor. A pair of lug arms and a swash plate arm are formed in an arc shape, and a single swash plate arm is arranged between the pair of lug arms to form a fitting portion. When the swash plate forms the maximum inclination angle, the fitting portion formed by the pair of lug arms and the swash plate arm is configured in a cylindrical shape, so that the flow resistance of the refrigerant at the fitting portion is minimized. Background technique [0002] Generally, an air-conditioning device used in a car is a device that uses a refrigerant to keep the temperature inside the car lower than the outside temperature, and includes a compressor, a condenser, an evaporator, and the like to form a circulation loop of the refrigerant. [0003] This compressor is used as a device for compressing and pressure-feeding refrigerant, and is driven by the power of an engine or an electric motor. [0004] The s...
