Abstract
Improving pump for hydraulic brake systems and the like, of the two stepped piston type, characterized in that the larger diameter chamber of the pump is in communication with the utilization circuit, and in this chamber the larger piston moves, while the small piston, rigidly joined to the largest, is movable in an extension of smaller diameter of said chamber and on said smaller piston acts the maneuvering member, the space comprised between the two pistons being in communication, on the one hand with the supply tank for a hole controlled by a check valve and, on the other hand with said larger diameter chamber by a hole arranged in the large piston and controlled by a check valve tared to open towards this space from a pressure equal to that obtained in the aforementioned camera at the end of the approaching race of the mandated organs, the first valve being in addition s, ready to be automatically opened, from the container to said space, when the pressure inside this container tends to surpass that of said space, and to be systematically opened by the larger piston in the rest position.
