Abstract
A scroll device has a fixed scroll, and orbiting scroll, and at least one cooling chamber configured to receive coolant to cool the fixed scroll or the orbiting scroll. A flexible conduit that curves around an orbital axis of the orbiting scroll may transfer coolant into or out of the at least one cooling chamber. The scroll device may have a motor with a motor jacket configured to receive coolant for cooling the motor. One or more involutes of the scroll device may comprise a wall coated or plated with a solid abrasion-resistant lubricant.
