Abstract
The valve block has a baseplate (1) with longitudinal ducts (11 to 15) for incoming and outgoing air, working-air ducts (16, 17) transversely thereto, connecting ducts (21 to 27) which open out in the connection side (18) in a specific hole pattern, and a well (19) for an electrical installation (20). Attached to the connection side (18) of the baseplate is at least one unit which consists of a directional valve (2) and of two pilot valves (3, 4) triggering this. The pilot valves (3, 4) are arranged in a housing (41) which is fastened by means of an attachment face (42) to an end face (43) of the directional valve (2). A plug base (92) projecting on the underside (29) of the housing (41) engages through a perforation (97) of the baseplate into the well (19) and has projecting contact lugs (93, 94) which are connected to contact terminals (95, 96) on the printed circuit board (20). In order to minimize attachment tolerances, there projects laterally at the lower end of the housing (41) of the pilot valves (3, 4), between the directional valve (2) and the baseplate (1), a plate-shaped extension (101) which has passage bores (102 to 107) corresponding to the hole pattern of the basepl…
