Abstract

A relay valve device, in particular a trailer brake valve for compressed air brake systems of two road vehicle circuits, whose passageway to the trailer brake is chargeable with air and purgeable air in a stepped manner in function of the braking pressure in at least one of the two braking circuits of the brake to contain the running of the tractor, the relay valve being provided with two relay pistons axially displaceable in opposite directions which, on the one hand, are chargeable by the pressure in the pass passage to the brake on the other hand, by the braking pressure in one of the two braking circuits and each of which carries a valve feel cooperating by a double valve body, thereby that the double valve body forms an intake valve with one of the valve seats and with the other valve seat an exhaust valve for air charging or purging of air brake step of the trailer, characterized in that the relay piston carrying the intake valve seat consist of two piston parts mounted one after the other and fixedly joined together, one of the piston parts of the loaded relay piston being, on the one hand, by the reserve pressure and, on the other hand, by the pressure of the passage to the trailer brake, while the other part of the relay piston is loaded, on the one hand, by the pressure of the second circuit of braking and, on the other hand, by the pressure of a spring accumulator control circuit.
