Abstract

870,868. Valves. ROTAX Ltd. Oct. 8, 1959 [Oct. 13, 1958], No. 32553/58. Class 135. A non-return valve comprises an apertured body part 4, adapted to be secured between the ends 12 of a pair of pipe parts, and a pair of spring-loaded flaps 6 cooperating with seatings 4a on the body part. A bridge piece 5 integral with body part 4 carries lugs 9 for a spindle 7 which also passes through lugs on the flaps 6 and carries the coil springs 11. While the body part 4 is shown as being circular and the flaps semi-circular these parts may be of any other suitable shape, for example, the body part 4 may be oval or rectangular.
