ABSTRACT:
A master cylinder having pistons sliding through high pressure lip seals during operation. When the pistons are at rest during release, the seals are in an open position relative to the pistons sufficient to permit the passage of fluid therepast for compensation. The open positions are attained by providing piston portions of smaller diameter than the high pressure seals. These piston portions may be at least parts of piston beveled edge surfaces, or such edge surfaces in conjunction with notches or grooves which are of smaller diameter than the high pressure lip seals. The notches or grooves may extend circumferentially completely around the pistons, or may be arcuately extending circumferentially spaced notches or grooves.
