A scroll type compressor having a housing unit in which a movable scroll element and a stationary scroll element are received in such a relationship that the movable scroll element orbits about the center of the stationary scroll element. The scroll type compressor further having a mechanical reinforced rotation preventing unit for preventing rotation of the movable scroll element about its own axis, and the rotation preventing unit having first stationary pin fixed to an inner end face of the housing unit and second movable pin fixed to an end face of a base plate of the movable scroll element, and a ring engaged with the first and second rings. A thickness T1 between the outer circumference of the first pin and the inner edge of the inner end face of the housing unit is set to be equal to or larger than 2.4 mm. A thickness T2 between the outer circumference of the second pin and the outer circumference of the base plate of the movable scroll element is set to be equal to or larger than 2.7 mm. A radial wall thickness T3 of the ring between the outer and inner cylindrical surfaces thereof is set to be equal to or larger than 1.7 mm.

Scroll type compressor with a reinforced rotation preventing means

A scroll type compressor using a crank mechanism having enough freedom so that an amount of eccentricity of the movable scroll member becomes variable. An elastic body is inserted between the facing surfaces striking each other in the inside of the crank mechanism so as to prevent generation of a noise due to the collision of the parts when starting up or shutting down the compressor.
