ABSTRACT:
A cross-sectionally U-shaped radially inwardly open piston ring for a piston slidably received in a cylinder and dividing the cylinder into a high-pressure side and a low-pressure side. The piston ring includes first and second radially inwardly projecting, circumferentially extending legs for being received in respective grooves of the piston, while straddling a radially outwardly projecting, circumferentially extending web forming part of the piston. That leg which is closer to the high-pressure side than the other leg when the piston ring is in place on the piston, is resiliently deformable in a direction parallel to the axis of the piston in response to pressures prevailing at the high-pressure side, whereby the leg is circumferentially pressed against the web forming part of the piston.
