Hydraulic valve device, in particular brake-pressure control valve for motor vehicles

摘要

In the valve device, which is composed of several valve blocks (1,2,3) which can be connected to one another, a ball (8) is arranged in a blind hole (7) in the flange face of a valve block (1). The ball (8) projects beyond the plane of the flange face (6) and engages in a recess, formed by a blind hole (10), in the associated mating flange face (11) of the valve block (2). Incorrect assembly of the valve block (1) containing the ball with an unsuitable valve block (3) without a recess is prevented by this arrangement. <IMAGE>
