ABSTRACT:
A scroll type fluid displacement apparatus including a housing divided into a discharge chamber and a suction chamber is disclosed. A fixed scroll member is disposed within the housing and comprises a first end plate and a first wrap which extends from one end surface of the first end plate. The discharge chamber is formed adjacent the fixed scroll member on the side of the first end plate opposite the side thereof from which the first wrap extends. An annular shaped dividing wall is formed at the end surface of the first end plate and extends into the interior of the discharge chamber. The discharge chamber is partitioned into two chambers by the dividing wall. At least one hole is formed through the dividing wall to connect the two chambers of the discharge chamber. The dividing wall is provided with a deflecting member for bending the fluid flow of the discharging fluid. At least one oil separating member is disposed in a fluid passageway upstream of a fluid outlet port from the housing. The separation of lubricating oil from the discharging fluid is promoted and the outflow of the oil is minimized.
