ABSTRACT:
A scroll type fluid displacement apparatus comprises a housing having an inlet port and an outlet port. An orbiting scroll has a circular end plate from which a spiral element extends and a pair of parallel grooves formed on the circular end plate. An Oldham coupling mechanism is disposed between the fixed scroll and the housing and includes a ring and a supporting member fixedly secured to the housing. The supporting member has a pair of parallel grooves formed on one end surface thereof. The ring has a pair of first parallel key portions and a pair of second parallel key potions. The second key portions are axially offset from the first key portions. The first key portions engage the grooves of the circular end plate of the orbiting scroll while the second key portions engage the grooves of the supporting means.
