Abstract

The design has twin circuit connections for use in trailer brakes. In the event of a break in the trailer brake connection, the pressure is restored in (2) seconds by the standby circuit. The first control connection has a two circuit brake valve connected to the trailer control valve. The second control connection has a throttle valve between the protection valve and the trailer coupling to the standbycircuit. The throttle consists of a piston (26) in a cylindrical housing (31) acted on by a spring (28). Two pressure zones are formed (25, 27) on either side of the piston. A ram (29) connected to the piston acts as a throttle by partially blocking an aperture in a separating wall (30) in the cylinder.
