  • Scroll-type fluid displacement device having flow diverter, multiple tip seal and semi-radial compliant mechanism
    Patent number: 6071101
    Abstract: A scroll-type fluid displacement device has two interfitting spiral-shaped scroll members which have predetermined geometric configurations. The novel design provides a flow diverter mechanism which directs intake fluid flow to break incompressible liquid accumulated into fine droplets which can be evenly engulfed by two suction pockets formed by the scrolls. This invention also provides a multiple groove tip seal mechanism for radially sealing off the compression pockets. This invention further provides a semi-radial compliant mechanism which maintains the radial compliant function of the orbiting scroll and at the same time transfers the load caused by the centrifugal force of the orbiting scroll from the scroll elements to the crank shaft.
