Abstract

1,155,758. Valves. NIPPON DENSO CO. Ltd., and TOYOTA MOTOR CO. Ltd. 23 Sept., 1966, No. 42633/66. Heading F2V. An air relief valve 1 has an inlet 1<SP>1</SP> and a seat 1<SP>11</SP> against which is urged a movable closure member 3. Either one or both of the abutting seat and closure member surfaces 2, 5, respectively, are covered with a wear-resistant elastomeric material, e.g. polyurethane. The closure member 3 has upturned guide projections 3<SP>1</SP> and further projections 3<SP>11</SP> which in conjunction with body projections 6<SP>1</SP> on a body plate 6 serve to locate the valve loading spring 4. Air passes to an outlet D via openings 6<SP>11</SP> and 6<SP>111</SP> in the plate 6; a chamber 7 and a diffuser 7<SP>1</SP> act as a silencer, the chamber 7 housing sound damping material 8 e.g. foam plastics material.
