Abstract
The area of the cross-section of a piston is reduced while maintaining the over-all dimensions of the cross-section such that the ring is usable in the conventional ring groove of a piston and cylinder assembly. The reduction in the area of the cross-section decreases the inertia of the ring for increased responsiveness to the operating conditions of the assembly. In accordance with a preferred embodiment, the area is reduced by forming a continuous groove in one of the surfaces of the ring.
