Abstract
A scroll compressor has a fluid brake for resisting and impeding objectionable reverse movement of the orbiting scroll member. The brake includes a one-way clutch interconnecting a drive shaft and a paddle disposed in the compressor oil sump, and optionally a rotor shield for controlling oil flow around the lower end of the motor rotor. A two piece paddle has a rotatable paddle having blades to impart angular momentum to the lubricating oil and a stationary housing having vanes to resist the angular momentum imparted to the lubricating oil by the blades of the rotatable housing.
