Abstract
A slotted guide ring for a piston-cylinder unit has a first free end portion and a second free end portion, which are arranged at a distance from one another in the circumferential direction of the guide ring, forming an axial through gap, and the end faces of which are arranged parallel to one another or substantially parallel to one another. In their projection on the central axis Z, the end faces enclose an acute angle α with the central axis Z of 15°≤α≤75°. On the guide side, a lubricant channel is formed which extends from the first free end portion to the second free end portion and which is open on both sides towards the axial through gap. The invention further relates to a piston-cylinder unit with such a guide ring.
