Abstract
A central release unit for a hydraulic clutch actuator has a plastic cylinder housing which is produced by injection molding and which has at least one cylinder wall provided, on an outer circumference, with a reinforcement sleeve. The reinforcement sleeve can be fastened to the cylinder wall after the injection molding of the cylinder housing, for which purpose a snap-action connection is provided on a forward end, which faces away from the pressure connection piece, of the reinforcement sleeve. The connection is formed by a radially inwardly bent detent portion of the reinforcement sleeve and by a rib integrally formed on the outer circumference of the cylinder wall. The reinforcement sleeve has a main portion which adjoins the detent portion and which is of conical shape complementary to an outer circumferential surface, which is of conical form in the reinforcement region, of the cylinder wall.
