AI Technical Summary

Benefits of technology

The present invention is about a compressor that can adjust its displacement and is small in size. The technical effect of this invention is to provide better control and reduce the size of the compressor.

Problems solved by technology

In this case, the inclination angle cannot be quickly changed in response to changes in the driving state, for example, of the vehicle, and high controllability cannot be achieved.
However, an increased pressure receiving area of the movable body increases the diameter of the actuator, which prevents the entire device from being reduced in size.
This, however, increases the stroke of the movable body when the inclination angle is changed.
As a result, the axial dimension of the actuator is increased, hindering the entire device from being reduced in size.

Embodiment Construction

[0026]One embodiment of the present invention will now be described with reference to the drawings. The compressor of the embodiment is a variable displacement swash-plate compressor with single-headed pistons. This compressor is installed in a vehicle and each included in the refrigeration circuit in the air conditioner of the vehicle.

[0027]As shown in FIG. 1, the compressor includes a housing 1, a drive shaft 3, a swash plate 5, a link mechanism 7, pistons 9, pairs of shoes 11a, 11b, an actuator 13, and a control mechanism 15, which is illustrated in FIG. 2.

[0028]As shown in FIG. 1, the housing 1 has a first housing member 17, a second housing member 19, a cylinder block 21, and a valve assembly plate 23. In the present embodiment, the front-rear direction is defined as shown in FIG. 1.

[0029]The first housing member 17 has a front wall 17a, which extends radially, and a circumferential wall 17b, which is integrated with the front wall 17a and extends rearward. A part of the first ...

Abstract

A compressor includes an actuator that is configured to change the inclination angle of a swash plate. A movable body, which is part of the actuator, has a primary acting portion and a secondary acting portion. The swash plate has a primary receiving portion and a secondary receiving portion. When the inclination angle of the swash plate is maximized, the primary acting portion contacts the primary receiving portion to push the swash plate. When the inclination angle of the swash plate is minimized, the secondary acting portion contacts the secondary receiving portion to push the swash plate.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a variable displacement swash-plate compressor.[0002]Japanese Laid-Open Patent Publication No. 52-131204 discloses a variable displacement swash-plate compressor (hereinafter referred to as a compressor). This type of compressor includes a housing, a drive shaft, a swash plate, a link mechanism, single-headed pistons, a link mechanism, and a control mechanism.[0003]The housing has a swash plate chamber, cylinder bores, and a discharge chamber. The drive shaft is rotationally supported by the housing. The swash plate is accommodated in the swash plate chamber to be rotational with the drive shaft. The link mechanism is located between the drive shaft and the swash plate. The link mechanism allows the inclination angle of the swash plate to be changed. The inclination angle is the angle of the swash plate in relation to a direction perpendicular to the axis of the drive shaft. The pistons are reciprocally accommodated i...
