Abstract : This patent discloses a piston ring which provides uniform circumferential pressure loading on the ring. The ring has two protrusions, and an optional third protrusions, which give full and uniform sealing contact between the ring, and a complementary peripheral groove in an associated piston, or housing, and a complementary cylinder movable wall, or sleeve, so that minimum pressure balance is sacrificed irrespective of any movement of the cylinder wall.
