Title:
OSCILLATORY PLATE TYPE VARIABLE DISPLACEMENT COMPRESSOR
Document Type and Number:
Japanese Patent JP2020122465
Kind Code:
A
Abstract:
To improve assemblability of a rotation stopping mechanism which stops an oscillatory plate from rotating in an oscillatory plate type variable displacement compressor.SOLUTION: In a rotation stopping mechanism 30, an outer peripheral surface 311 of an inner ring 31 is formed into such a convex surface that a cross-sectional shape cut with a plane containing a center line L2 of the inner ring 31 is convex radially outward, and an inner ring ball groove 312 extends in parallel with the center line L2. An inner peripheral surface 322 of an outer ring 32 includes a rotor side cylindrical inner peripheral surface 322a and a piston-side diameter-reduced inner peripheral surface 322b of the cylindrical inner peripheral surface 322a, and an outer ring ball groove 325 extends in parallel with a center line L5 of the outer ring 32. An inner peripheral surface 343 of a retainer 34 is formed into a curved surface along the outer peripheral surface 311 of the inner ring 31, an outer peripheral surface 342 of the retainer 34 is formed into a curved surface along the diameter-reduced inner peripheral surface 322b of the outer ring 32, and a fall stopper member 35 is fitted at a position which is more on a rotor side than the cylindrical inner peripheral surface 322a of the outer ring 32.SELECTED DRAWING: Figure 3
