Scroll compressor with structure for preventing reverse rotation

摘要

A scroll compressor includes structure between an eccentric and a slider block that separates the scroll wraps when the orbiting scroll is driven in a reverse direction by entrapped fluid. In the prior art, entrapped fluid sometimes has driven the orbiting scroll in a reverse direction at shutdown, resulting in undesirable noise. The present invention stops movement of the orbiting scroll relative to the fixed scroll during reverse rotation by opening the fluid chambers dissipating that pressure.
