Patentansprüche:Patent claims: 1. Steuerventil für Druckluftbremsen, bei dem als Steuerkolben eine eingestülpte, leicht konische Rollmembran aus Gummi Verwendung findet, dadurch gekennzeichnet, daß die mit der Membran (b) in Berührung kommenden Büchsen (c und d) aus einer nichtmetallischen, gegen Wasser, Öl und Gummi unempfindlichen Masse (z. B. einem unter dem Namen Bakelit bekannten Phenolformaldehyd-Kondensationsprodukt) bestehen.1. Control valve for compressed air brakes, in which an inverted, slightly conical rolling diaphragm made of rubber is used as the control piston, characterized in that the bushes (c and d) coming into contact with the diaphragm (b ) consist of a non-metallic, against water, oil and Rubber-insensitive mass (e.g. a phenol-formaldehyde condensation product known under the name Bakelite). 2. Steuerventil für Druckluftbremsen nach Anspruch 1, dadurch gekennzeichnet, daß in der Büchse (d) eine oder mehrere Bohrungen (A) vorgesehen sind, durch die die sich ansammelnde, von der Druckluft 8S mitgeführte Feuchtigkeit sofort wieder in den Kanal (/) der Druckluftleitung abtropft. 2. Control valve for compressed air brakes according to claim 1, characterized in that one or more bores (A) are provided in the sleeve (d) through which the accumulating moisture carried by the compressed air 8 S immediately back into the channel (/) drips off the compressed air line.
