Abstract

1503489 Valves MOLEHURST Ltd 17 March 1975 [28 March 1974 20 Aug 1974] 13907/74 and 36491/74 Heading F2V [Also in Divisions B5 and B7] In a pneumatic tyre (see Division B7) having a plurality of air compartments arranged in succession around the circumference of the tyre, inflation of the tyre is effected through a passage 26 connected to each compartment by a respective one-way valve 30, Fig. 5, and deflation is effected through respective one-way valves 32 connecting each compartment to a passage 28, the passages 26, 28 being connected to a main valve 50, Fig. 4, including a valve member 71 movable against the action of a spring 72 into the position illustrated in which ports 62, 66 opening into the passages 26, 28 are in communication with an open main air inlet/ outlet port 59. When the member 71 ceases to be depressed the spring 72 moves the member 71 into a position such that the ports 62, 66 are not in communication with each other and the port 59 is closed. A modified valve 50 (Fig. 3, not shown) employs two valve members biased to block respectively the port 59 and a passage connecting the ports 62 and 66.
