Abstract

251,376. Leach, R. W. Feb. 17, 1925. Piston-packing substitutes. -A fluidtight joint between a pair of relatively-movable parts is effected by providing in one of the parts a pair of grooves c with oppositely chamfered surfaces d between the grooves, whereby a wedging action is produced on lubricant in the grooves during movement in either direction. The surfaces d may be arranged to form a ridge or a trough.
