Abstract

A valve for regulating pressure in front brakes 21 of a vehicle pneumatic brake system comprises a valve body (2) accommodating an auxiliary piston (4) installed coaxially with a differential piston (3), the pistons (3,4) being arranged to have a limited movement relative to each other and to move bodily. The auxiliary piston (4) is arranged in the valve body (2) so that it is caused to move towards the differential piston (3) by increase of driver's control pressure in chamber (5) and come into contact therewith for the two pistons (3,4) to move bodily and is acted upon in opposition to this movement by load responsive rear brake pressure in chamber (6). The interior of the valve body (2) is divided into the supply chamber (5) bounded in part by the smaller working surface (8) of the differential piston (3), the regulation chamber (6) bounded in part by the differential surface (11) of the differential piston (3), and a distribution or output chamber (7) bounded by the larger working surface (14) of the differential piston (3). The valve (1) comprises a double valve element (15) operated by the differential piston (3) and arranged to effect, depending on the position of the latter, admission of compressed air into the distribution chamber (7) from the chamber (5) (Fig. 1) or from a separate air supply when it is a relay valve (Fig. 2) and exhaust therefrom into the atmosphere. <IMAGE>
