Abstract

1316248 Valves H-G RISSMANN 18 Oct 1971 [20 Oct 1970] 48273/71 Heading F2V A valve for use in pneumatic tyres of vehicles comprises a casing with valve seat 3 and air passage apertures 8 and a closure member 10 of elastomeric material disposed for axial movement within the casing and which in the closed position is held against the seat 3 and also against the inside wall of the casing at 12. The member 10 may be loaded by a spring or by an extra portion of elastomeric material 10<SP>1</SP>, which may be integral with the member 10 and provided with internal cavities, or by the pressure of gas inside the tyre acting through an opening (17, Figs. 3-6, not shown). A pin 2 may be provided to open the valve during rest. The pin has a head 13 which acting on shoulder 5 in the casing limits movement of said pin. The casing may be constituted by two sleeve portions 1 and 4 as in Fig. 2 or may be constructed in one piece. A ring seal 6 is provided on the casing. To facilitate the flow of air the apertures 8 may be extended.
