Abstract

518,600. Piston packing. BENDIX, Ltd., and ROBERTS, G. P. Oct. 14, 1938, No. 29763. [Class 122 (i)] The piston c for use in the master or brake cylinder of a hydraulic braking system is filled with a cup-shaped rubber or like flexible sealing member a having a lip or flange a<1> of such form that its free edge is held out of contact with the cylinder wall. As shown a wire ring e embedded in the free edge of the lip holds the edge of the lip contracted to a diameter slightly, less than the cylinder. In modifications the free edge is thickened and curved, or is formed as a thick inwardly directed flange. The peripheral surface of the lip is slightly curved in a longitudinal direction, and an expanding ring h is used to urge the central part of the lip into contact with the cylinder wall when there is little pressure in the cylinder.
