Abstract

A dual-circuit dual line trailer control valve with split retroaction piston (20, 23) is proposed. The two parts (20 and 23) of the retroaction piston are arranged one inside the other and the outer of the two parts has axial shoulders (21), by means of which it bears on one (3) of the two brake pistons (2, 3). <IMAGE>
