  • Scroll-type fluid machine having the eccentric shaft inserted into the moving scroll
    Patent number: 5336068
    Abstract: A scroll-type fluid machine is provided in which the oscillating motion at the orbiting movement of a moving scroll is considerably decreased. A projecting portion is formed at the center of a moving scroll and moving scroll shaft bearings are fixed in a shaft hole of the projection portion. The moving scroll is positioned such that its center of gravity is positioned at a portion between the moving scroll shaft bearings. The moving scroll is driven at the center of gravity of the moving scroll to prevent the moving scroll from being oscillated at the orbiting movement. As a result, noise is mitigated and the life of the fluid machines is prolonged since wear caused by the oscillating movement is restricted.
