Abstract

683,463. Pistons. SCHWEIZERISCHE LOKOMOTIV-UND MASCHINEN-FABRIK. Sept. 20, 1948 [Sept. 22, 1947], No. 24558/48. Class 122(i) [Also in Groups XXVIII and XXIX] In a liquid-operated, radial, reciprocating-piston engine of the type in which the piston end 15 remote from the working space of the cylinder. 3 slides on a face 11 receiving the piston forces and which is recessed to provide a pressure chamber supplied with liquid from the working space through a throttling aperture, the cylinder 3 is formed with an enlargement 33, Fig. 5, which guides an enlargement 32 of the piston end, the enlargement 33 being of such length that at the piston inner dead centre position it approaches closely the face 11 and the piston enlargement 32 is of such length that a substantial part of its length is still engaged in the enlargement 33, in the piston outer dead-end position. The enlargement 32 is recessed to form a seat for a spherical segment 28 which engages the face 11. The segment 28 is formed with a pressure chamber 16. Alternatively the enlargement 32 may be formed with a pressure chamber in its end and engage the face 11 directly. The enlargement 33 is cut away at its end to avoid one or more ledges 27 which retain the piston end against the face 11. The pressure chamber may be constituted by grooves in the end of the piston, the grooves being radial, circumferential or chordal. Specification 678,917 is referred to.
