AI Technical Summary

Benefits of technology

The present invention provides a swash plate compressor that can smoothly change the angle at which the swash plate is inclined. This allows for smoother operation of the compressor.

Problems solved by technology

A sliding resistance increases by this twist, and the mobile body becomes unable to move smoothly to an axial direction of the rotation shaft.
As a result, the inclination angle of the swash plate becomes unable to be smoothly changed.

Embodiment Construction

[0017]Hereinafter, a preferred embodiment of a variable displacement type swash plate compressor according to the present invention will be described with reference to FIGS. 1 to 4. In the following description, the variable displacement type swash plate compressor will be simply referred to as a compressor. The compressor is used for a vehicle air conditioner. Further, a left side in FIG. 1 will be defined as a front side, and a right side will be defined as a rear side.

[0018]As illustrated in FIG. 1, a housing 11 of a compressor 10 is configured by a first cylinder block 12 and a second cylinder block 13, which are joined to each other, a front housing 14, which is joined to a front end of the first cylinder block 12, and a rear housing 15, which is joined to a rear end of the second cylinder block 13.

[0019]A first valve / port forming body 16 is present between the front housing 14 and the first cylinder block 12. A second valve / port forming body 17 is present between the rear hous...

Abstract

A mobile body and a swash plate are coupled to each other via a columnar coupling pin provided on an outer peripheral part of the swash plate. An insertion hole through which the coupling pin is passed is formed in the swash plate. The insertion hole has a guide surface for guiding the coupling pin and for changing the inclination angle of the swash plate following movement of a mobile body to the axial direction of a rotation shaft. The guide surface has a flat surface part which is inclined to a moving direction of the mobile body. The flat surface part is set such that a perpendicular line of the flat surface part and an axial line of the rotation shaft cross in a region surrounded by a sliding part, viewed from a direction orthogonal to both an axial direction of the rotation shaft and a first direction.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a variable displacement type swash plate compressor.[0002]A compressor of this kind has been disclosed in Japanese Laid-Open Patent Publication No. 52-131204. The compressor of this kind has a swash plate and a mobile body that moves to an axial direction of a rotation shaft for changing an inclination angle of the swash plate. The compressor further has, in the housing, a control pressure chamber into which a control gas is introduced. The mobile body moves to the axial direction of the rotation shaft, when the pressure inside the control pressure chamber is changed following the introduction of the control gas. Following the movement to the axial direction of the rotation shaft, the mobile body transmits force to a center part of the swash plate to change the inclination angle of the swash plate. As a result, the inclination angle of the swash plate is changed.[0003]The above configuration of transmitting force from...
