摘要： In a brake valve of the type in which a given ratio is maintained between a master pressure developed by a brake pedal and an actual brake pressure, an arrangement is provided for continuous, rather than stepwise, adjustment of this ratio. The brake valve includes a control piston which is subjected to the master pressure and which, by the displacement thereof, opens and closes connecting channels between an accumulator containing a primary pressure fluid and a brake, as well as between the brake and a fluid collecting tank. The control piston and a measurement piston apply counter forces to the arms of a balance beam whose lever ratio determines the degree of feedback of the instantaneous brake pressure to the control piston. A stop is provided in the path of the axis of the control piston, which limits the stroke of the piston, to prevent the overloading of the balance beam during abnormally high braking pressures such as occur, for instance, during panic braking.

摘要： A radial piston pump has a housing bounding a suction chamber therein and provided with a plurality of pressure ports spaced from one another in circumferential direction of this housing, and with at least one suction port. A plurality of valve units spaced from one another in the circumferential direction of this housing are provided, each of which includes a pressure valve element located in a respective one of the pressure ports and a sleeve member mounted in the same pressure port radially outwardly of the pressure valve element so as to form, together with the latter, a pressure chamber inwardly of and communicating with the pressure port. A plurality of circumferentially extending channels are formed in this housing and intersect the respective pressure chambers.
