<p>1. A system for generating brake pressure comprising a master cylinder (1) having at least one primary piston (8, 8b) associated to at least one hydraulic brake circuit being coupled to a vacuum brake for amplifier (2, 2b) having first (13) and second (15) axially opposing walls, a diaphragm or piston (17, 19b) dividing the brake force amplifier into a vacuum chamber (20) and an atmospheric chamber (21), as well as a control valve (3, 3b) of the brake force amplifier being arranged in a hub portion (22) of the piston (17, 19b) and being mechanically coupled to an actuating member connected to the brake pedal for actuation thereof, the primary piston (8, 8b) of the master cylinder being connected to the piston of the brake force amplifier by means of a hollow actuating rod (26, 26b), characterized in that the master cylinder (1) is fixedly connected to a first wall (13) of the brake force amplifier (2, 2b) corresponding to the atmospheric chamber (21) and has a slidable thrust member (63, 63b) arranged at the end thereof being remote from the brake force amplifier (2, 2b) and receiving the rod of the brake pedal, the control valve (3, 3b) permanently communicating with the atmosphere through a central opening formed in the second wall (15) of the brake force amplifier (2, 2b) corresponding to the vacuum chamber (20) and being operated by an actuating rod (28) extending within the hollow actuating rod (26, 26b) and having its opposing ends coupled to the slidable thrust member (63, 63b) and a movable valve closure member (36, 36b) of the control valve (3, 3b), respectively.</p> |
