<p>PURPOSE:To make a thrust load zero and abolish a thrust bearing by making an oscillating member be in axial contact with a static member directly or through an intermediate member without a main shaft, and regulating a minimum volume position of a compressor. CONSTITUTION:When a main shaft 13 of a compressor is driven, a driving plate 14 and a swash plate 12 are rotated, and a piston support 21 is oscillated. A piston 31 is thus reciprocated in a cylinder, and a refrigerant is run into a suction port 301. In the case that a compressor capacity is varied from a maximum to minimum, a swash plate sleeve 15 is slid and a tilting angle of the swash plate 12 is gradually decreased. A support sleeve 25 engaged with the swash plate sleeve 15 through a roll bearing 29 is moved by means of a sliding pin 30 and a recession 251 of the support sleeve 25. An end 252 of the support sleeve 25 on the side of a cylinder head 4 is abutted against an end 202 of a bearing housing 201 of a cylinder block 2.</p> |
