Abstract

520,351. Valves. NAPIER & SON, Ltd., D., and TRYON, H. C. Oct. 19, 1938, No. 30219. [Class 7 (vi)] [Also in Group XXVI] A scraper ring, which may be applied to the engine piston or to the cylinder A in which a sleeve valve B reciprocates, is constructed of a complete ring D arranged loosely in a groove C in the cylinder A, or in the groove of a piston, a split scraper ring E which bears on the sleeve B or on the cylinder of an engine, and a resilient device between the rings D, E, which preferably takes the form of a sinuous spring F bearing on 'the two surfaces D, E. The ring E can thus yield in a radial direction and maintains a constant pressure which is unaffected by lack of true concentricity between the parts. The ring D may be formed of U-shape in cross-section, or as shown in Fig. 3 of E-shape with two scraper rings J, and sinuous spring rings J<1> arranged in the limbs of the E-member H, which is formed with an extension H<1> arranged in an annular extension G<1> of the groove G. Oil-removing grooves H<2>, H<3> are provided. In a modification, the ring D instead of being formed as one integral ring is formed as a split ring having interlocking ends, so that it is then not necessary to form the groove C between parts A, A<1>, which have to be separated completely to insert the scraper ring.
