Abstract

762,506. Valves. NSU WERKE AKT.- GES., & WANKEL, F. Jan. 6, 1954 [Jan. 6, 1953], No. 403/54. Class 7 (6). [Also in Groups XXVI and XXIX] A disc-type rotary valve for an internal combustion engine is sealed to the cylindei head or other part C on which the valve operates by a non-circular sealing element comprising a number of arcuate sections A B each having one of its end faces in overlapping contact with the outer periphery of an adjacent section The element is housec in a groove in the part C and urged by the pressure of the sealed fluid both radially outwards into contact with the surface F of the groove and axially so that its face G bears on the valve. The sections are located by pins K thereon engaging, with clearance, holes in the part C and each section is provided near its overlapping end M with a projection O running parallel to the line P perpendicularly bisecting the line joining the centres of curvature of the adjoining sections and adapted to slide in a corresponding recess in the part C.
