摘要： The present invention is a pressure limiting valve (10), comprising a valvehousing (12), a valve piston (18), and a limit pressure adjusting spring (28), and in the valvehousing (12), at least One valve inlet (14) and at least one valve outlet (16) are provided,and the valve piston (18) is open where the valve inlet (14) and the valve outlet (16) areconnected to each other. Position (B) and at least one closed position (D) in which thevalve inlet (14) and the valve outlet (16) are blocked from each other can occupy thevalve piston (18) with the sealing surface (40 ) Having a first piston ring (20) and a secondpiston ring (22), the sealing surface (40) of the first piston ring (20) in the closed position(D) is Pressure limit acting on the piston ring (22) It is pulled and closed against thehousing mounting portion (24) so as to be sealed by a pneumatic force directed in adirection opposite to the force of the spring (28), and in the valve piston (18), There is apneumatic passageway (26) that implements a safety valve function, and the pneumaticpassageway (26) is spring-loaded located on the opposite side of the second piston ring(22) from the valve outlet (16). It relates to a pressure limiting valve (10) which can beclosed by a biased safety valve body (32).
