Axial sealing mechanism for a scroll type compressor

Abstract From the Canadian patent

This invention discloses an axial sealing mechanism for axially sealing an orbiting scroll and a fixed scroll of a scroll type compressor. The compressor includes a driving mechanism for driving the orbiting scroll in an orbital motion and a block member fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block member and the fixed scroll define an intermediate chamber in which the orbiting scroll is disposed. The intermediate chamber is divided into a first and second chamber by an end plate of the orbiting scroll. A first conduit which is sized to produce a pressure throttling effect links the second, chamber and the discharge chamber of the …
