Abstract
A scroll-type machine has a motion controlling member for preventing relative rotation between a first and a second scroll member while allowing relative orbiting motion therebetween. The scroll-type machine includes a novel arrangement of a spring or other flexible member for biasing the motion controlling member in a specific direction. The biasing of the motion controlling member operates to reduce the mechanical impact noise or rattle which is caused by the vibration of the machine's operating components.
