Patent ID: 10214191

Abstract:
A valve unit (1, 1′) for modulating the pressure in a pneumatic brake system, has a brake pressure inlet (3), a brake pressure outlet (4) and a venting outlet (5), a pneumatically controllable main valve (6, 7) and a pilot valve (8, 9), embodied as a solenoid valve and assigned to the main valve (6, 7), which are arranged in a valve housing (2, 2′) subdivided by a plane of division (10), into a main housing (11, 11′) and a housing cover (12). For fixing the housing cover (12) on the main housing (11, 11′) a bracket element (62.1) is fixed to the main housing (11, 11′) and bears with a largely planar pressure plate (63) generating an elastic prestressing force on a planar outside wall (64) of the housing cover (12) oriented parallel to the plane of division (10) of the valve housing (2, 2′).
