Abstract

Pneumatic control valve (1), in particular dual-circuit brake transducer in a compressed-air brake system of a vehicle for correcting a brake pressure which corresponds to a desired braking action, having at least one first valve system (10, 14) which is arranged in a housing upper part (2) and has a first valve piston (10) which interacts with a first annular plate valve (14) and can be actuated manually or by means of an actuator via a spring element (9) by means of a plunger piston (4), having a second valve system (30, 37) which is arranged in a housing lower part (3) with a coaxially arranged second valve piston (30) which can be actuated pneumatically and/or mechanically by the first valve system (10, 14) and with a second annular plate valve (37) which interacts therewith, the plunger piston (4) having, radially on the inside, an axial cylindrical projection (4a, 4b), by means of which the plunger piston (4) is guided in cylindrical guides (2a, 42b) in the region of the housing upper part (2) and in the region of the housing lower part (3). In order to configure the control valve to be small axially and to relieve the first valve piston (10) of transverse forces and tilting moments, the said first valve piston (10) is guided via the plunger piston (4) in the cylindrical guide (2a) in the housing upper part (2).
