ABSTRACT:
A short hydraulic master cylinder includes a secondary pressure chamber recuperation valve assembly which is mounted in the side of the master cylinder body and incorporates a center valve operable by a lever which engages the rear surface of the front seal support flange of the secondary piston. Thus, the portion of the secondary chamber defined by the master cylinder bore is devoid of all valve and operating linkage components. Recuperation flow to the primary chamber is via a center valve assembly connected by bores to the space between the seals of the secondary piston, and the passage through which the lever extends.
