Abstract
A hydraulic pressure generator comprises a body in which is formed a bore, at least one piston mounted slidably in the bore, an annular sealing mechanism located in the bore, and the piston being slidable from a rest position during operation of the generator to cooperate with the sealing mechanism and divide the bore into a working chamber connectable by an output passage to a hydraulic actuator. A refill passage is connected to a source of hydraulic fluid. The output passage is formed in part between a first surface fixed in the bore and a second surface formed on a member mounted in the bore.
