Abstract

In a configuration in which a driving shaft 8 supported in a cantilever manner is connected with a drive plate 15 through a link mechanism 57 and a wobble plate 19 capable of rotating relatively for it is connected with the central shaft 32 through a rotation stopping mechanism 56 including the universal joint 37, load in the radial direction which is component of force of compression reaction force acts on the rotation stopping mechanism 56. By providing projections 53 and 55 which can be mutually engaged between the driving shaft 8 and the drive plate 15 and a special load supporting part composed of an inclined face 54 and engaging the load supporting part in the vicinity of operation region for bringing the maximum discharge capacity, load in the radial direction is supported by the driving shaft 8.

Description

Technical field

[0001] The present invention relates to a positive displacement pump or compressor for compressing refrigerant in an air conditioner, and more particularly to a wobble plate type compressor suitable for a wobble plate type having a large displacement such as a compressor for buses Variable displacement compressor. Background technique

[0002] Japanese Unexamined Patent Publication No. 2-275070 describes a rotation stop mechanism for a wobble plate in a wobble plate type variable displacement compressor. The rotation stop mechanism includes a guide rod provided on a part of the outer periphery of the wobble plate in parallel with the drive shaft. However, the unsolved problem is that when the rotation stop mechanism is provided on the outer peripheral portion of the wobble plate, the radial size of the compressor increases and the compressor becomes larger. Also, according to the structure, since the moment of inertia of the rotating part is borne by the outer per...
