Screw-in brake servo unit - has discharge-sided stop of closure part, fitted into housing sleeve

摘要

The unit has a housing-fastened stop (22) on the discharge-side, which is formed by a closure part (4). This is inserted with its complete axial length into a housing sleeve (2), which accommodates the pressure reduction valve. Closure part and sleeve are irremovably connected by a deformed section (52). The discharge-sided brake circuit connection is also formed on the housing sleeve, and provided with an internal thread (11). The closure part has an external thread (46), meshing with an internal thread (48) in the sleeve. It also has an axial pressure medium passage (50) with polygonal profile. USE/ADVANTAGE - Small screw-in brake servo unit is continuously adjustable, and has fewer components than conventional servo unit.
