A scroll compressor includes a discharge valve assembly for blocking compressed refrigerant flow from the discharge chamber through the scroll members. This blocking of flow results in the elimination of reverse rotation at shut down. The discharge valve assembly includes a leakage path which allows a limited amount of refrigerant flow past the discharge valve to eliminate the forming of a vacuum during powered reverse rotation. In one embodiment, a valve located in the leakage path provides a time delay to optimize the performance of the discharge valve assembly.

Scroll machine with reverse rotation protection

A plastic terminal box is secured to a shell of a working machine. The plastic terminal box includes a plastic body which is secure to the shell and a plastic cover which is sealingly and releasably secured to the plastic body. The plastic body defines an aperture into which is inserted an electrical terminal of the working machine. A seal is located around the terminal and between the shell and the plastic body. The terminal and its associated electrical connections are thus isolated by the plastic terminal box due to the seal between the body and the shell and by the seal between the cover and the body.
