Abstract
PURPOSE: To prevent a piston ring from being collided with a piston land and make it easy to radiate heat from the piston, by fitting the ring with a U-shaped cross section to the land so that the ring grasps the land with a certain force.
CONSTITUTION: In a volumetric machine equipped with a cylinder S and piston P, a ring R, having a U-shaped cross section corresponding to the shape of a piston land 3 and having a width 1 in its free state a bit smaller than the size of the land 3, is so designed that it can grasp the land 3 with a certain force when it is fitted to the land 3. A portion 2 is slightly projected to increase the closeness of the ring's inner surface to the land's surface, while the expansive force of the ring itself makes it close to the inner surface of the cylinder S. This construction permits to use a large ring groove 5 for making the gas pressure work well on the ring R in the rear, and the ring R is never collided with the land 3 in the ring groove.
