A silencer is described for damping the outflow noise of compressed air from compressed air appliances, in particular compressed air appliances of vehicles, with an inlet port, with at least one outlet port and with a pot-like housing which is arranged between these ports and which has a pot casing and a pot bottom, a sound-absorbing material in the form of a cartridge of a filter knit, serving for noise damping, being arranged in the inner space of the pot-like housing, characterized in that a layer of fibrous material is arranged between the cartridge and the pot casing.

Electropneumatic control valve for a pneumatic brake system of a vehicle having a relay valve housing in which an axially adjustable control piston is arranged for actuating a valve seat arrangement which switches the compressed-air flow between at least one exterior brake line connection, a supply pressure connection and a bleeder connection. The control piston is axially guided by means of a coaxial guiding arrangement. The guiding arrangement comprises a separate guiding sleeve which is stationarily fastened to the pilot valve housing and which is provided with an upper guiding section which, for the axial guidance, corresponds with a passage bore in the control piston, and which, in addition, has a lower tube section of a smaller outside diameter adjoining the upper guiding section in order to guide the outgoing air flowing through an integrated axial bleeder duct directly to the bleeder connection.
