Abstract

773,642. Hydraulic brakes. TEVES, H., and TEVES, E. A., [trading as TEVES MASCHINEN - UND ARMATURENFABRIK KOMM-GES., A.]. Sept. 13, 1955 [Oct. 2, 1954], No. 26232/55. Class 103 (1). A pressure regulating device is inserted in the conduit of an hydraulic braking system so that the pressure output from the master cylinder 27 is divided between the two branch conduits 3 and 4 in such a way that the pressure in one conduit is increased and in the other reduced, and so that the sum of the pressures in the two pipes rises linearly in proportion to the output from the master cylinder. The characterization is obtained by the use of a control device, as shown in Fig. 1, wherein the supply pressure 2 acts against the pistons 5 and 15 having ports therein controlled by ball valves 9 and 19. The piston 5 bears against a spring 6 which requires a greater than linearly increasing force to compress it while the spring 13 tending to open ball valve 9 is of linear force compression type. Piston 15 on the other hand bears against a spring 16 of linear force-compression type the ball valve 19 being acted upon by a non-linearly increasing force to compress it. By a suitable choice of springs it is possible to obtain the characteristics outlined above such that the mean of the two branch pressures, shown in thick lines in Fig. 2c is linear.
