Abstract

A scroll-type fluid displacement apparatus including at least two scroll members, with each scroll member having a plate and a spiral involute extending from the plate. The spiral involutes mesh to define fluid voids between the scroll members that become smaller towards the center of the scroll members. The apparatus also includes an eccentric crank mechanism having an elongated shaft with an eccentric portion. The elongated shaft is connected at one end to a motor and at another end to a machine, while the eccentric portion is rotatably received by one of the scroll members such that the scroll members will orbit with respect to one another as the shaft is turned by the motor. The apparatus also includes at least one eccentric guide for assisting the eccentric crank mechanism in retaining the scroll members in an orbiting relationship. According to one embodiment, the eccentric guide comprises a second eccentric crank mechanism having an elongated shaft with an eccentric portion rotatably received by one of the scroll members. According to another embodiment, the elongated shaft of the second eccentric crank mechanism is connected at one end to a motor and at another end to a machine.
