Abstract:
The present disclosure provides a sealing ring assembly with one or more piston-integrated gap cover features, configured to seal a high-pressure region from a relatively lower pressure region of a piston and cylinder device. The sealing ring assembly may include two rings which each may include one or more ring segments. The one or more gap-cover features, which may be in the form of protrusions in the piston ring groove, may engage with corresponding flat sections of the ring segments. As the sealing ring wears, the gap-cover features may stay engaged with the ring segments, thereby maintaining a seal.

Claim (Index 18):
A device comprising:\n a cylinder comprising a bore having an axis; a first ring comprising at least one first ring interface and an axially rearward surface; a second ring comprising:\n at least one second ring interface, and \n at least two radially outside surfaces proximate to each second ring interface; and \n a piston configured to travel along the axis within the bore, the piston comprising:\n a ring groove in which the first ring is arranged axially in front of the second ring such that no first ring interface is azimuthally aligned with a second ring interface, wherein the ring groove comprises a rear land, and \n at least one gap-cover feature that extending axially forward from the rear land, wherein the at least one gap cover feature comprises:\n an axially forward surface configured to engage the axially rearward surface of the first ring, and \n a radially inward surface configured to engage the at least two radially outside surfaces of the second ring.
