SWASH PLATE TYPE COMPRESSOR

摘要

A swash plate type compressor is provided to form connecting parts between a race securing part and anti-rotation protrusions to prevent damage or separation of the anti-rotation protrusions when a compressor is driven or in an overload state to improve strength and durability of the anti-rotation protrusions. A cylinder block(11) has a plurality of cylinder bores forming a hollow. A piston is inserted into the cylinder bore to be assembled with the cylinder bore slidably. A swash plate shaft has a swash plate interacting with the piston and passing through the center of the cylinder block. A thrust bearing supports a thrust of the swash plate and the swash plate shaft. A race(21) is interposed between the cylinder block and the thrust bearing, forming a hollow disc shape and having a plurality of protrusions(22) extended in a radial shape along an outer peripheral surface. An anti-rotation unit(30) includes a hollow race securing part(31) protruded at the center of the cylinder block and a plurality of anti-rotation protrusions(32) separated from the race securing part and protruded to prevent rotation of the race. The anti-rotation unit includes a plurality of connecting parts(33) connected between the race securing part and the plurality of anti-rotation protrusions, extended in a radial shape.
