Abstract

Steering valve for trailers adjustable through two circuits, especially for pneumatic braking devices in cars, with two neighboring and movable control pistons in the same direction, each coupled to a circuit, one of these control pistons carrying a part of the outlet valve, and with another control piston also movable in the same direction for an auxiliary and/or fixing brake, being provided between the auxiliary and/or fixing brake control piston and the control piston carrying a part of the outlet valve a control spindle and a double valve body that with a retracted edge of its housing forms the inlet valve, characterized in that the control spindle to the coupling object of one of the two circuits and the conduit of the supply of the pressure medium is configured in a hollow form, elongated beyond the control piston of the auxiliary and/or fixing brake, and sealed there in the housing.
