Abstract

Valve for trailer brake for braking systems, by means of two-way pressure in trailers for vehicles, with a control piston capable of being loaded through the brake line and a safety brake piston loaded through the reserve line, a discharge valve being formed by parts of the control piston and the safety brake piston, an intake valve being provided next to the safety brake piston, and a stop valve being formed by parts of the piston of the safety brake. Safety brake with a retractable surround box edge; characterized in that the intake valve is formed exclusively by parts of the safety brake piston and has a valve surface movably supported on the safety brake piston, and because the shut-off valve, and the intake valve are formed based on three movable parts relative to one another and the retracted housing edge is structured and arranged in conjunction with parts of the safety brake piston so that in the case of emergency or safety braking it closes first the shut-off valve, and the intake valve is opened in the closed closing movement of the shut-off valve.
