Abstract

1,067,564. Piston packing. ROBERT BOSCH G.m.b.H. May 4, 1964 [May 17, 1963], No. 18362/64. Heading F2T. Piston packing, particularly for the piston 2 of a compressed-air brake cylinder 1, comprises two annular members 11, 12 housed in a groove 6 in the piston and having tapered radially outward extensions 13, 14 inclined axially one towards the other and terminating in sealing lips 15, 16 urged against the cylinder wall by a garter spring 17 housed between the members 11, 12 which may be interconnected by an integral web 8 as in Fig. 1 to form a U-section ring or may be separate rings (Fig. 4). In a modification (Fig. 2) sealing lips (19), (20) are provided on the outer faces of the members (11), (12). The space between the members may be filled with grease.
