Abstract
Modifications of a scroll compressor provide a bellows suitable for liquid cooling and a plunger actuated seal for the scroll tips of various equipment. A bellows spans the fixed and the orbiting scrolls and hermetically seals the scroll device. Using two bellows, the present invention allows for liquid cooling of a compressor with an inlet and an outlet to exhaust heated coolant to a heat exchanger. Then the scrolls have a spiral upon a plate that ends in a tip. A seal upon the tip that abuts the fixed scroll upon a biased plunger modifies existing scroll designs to maintain the seal in contact with the fixed scroll. The modifications also provide an improved coating that seals the fixed and orbiting scrolls to each other without the use of epoxy, disassembly, and cleaning.
