Claims

[Scope of utility model registration request]

A drive plate having a large diameter disk part and a small diameter cylindrical part and having an L-shaped cross section is provided in the crank chamber so as to be able to swing freely, and a radial bearing is provided between the drive plate and the small diameter cylindrical part. ,
In a oscillating swash plate type compressor in which a wobble plate is swingably supported with its rotation regulated by thrust bearings interposed between the large-diameter disc part and the wobble plate, the bottom of the crank chamber is The anti-rotation member is loosely fitted into the anti-rotation guide rod that extends in the front-rear direction and is suspended horizontally, and a notch formed in a gate shape is provided at the lower end of the wobble plate. a rocking swash plate, which is fitted into the rotation preventing member so as to be slidable in the vertical direction, and has an oil supply hole bored in the ceiling surface of the notch, with its tip facing the radial bearing. A lubrication mechanism for the wobble plate bearing in a mold compressor.
