Zusammenfassung: | PURPOSE: To avoid complete failure in a brake device based on the suction of air due to an error in a two-circuit brake device. CONSTITUTION: An auxiliary hydrounit 43 has a plunger 48 and a pressure piston 51, slidable in an axial direction aganist a return spring 52 in a work cylinder 50, restricts control and pressure chambers 53 and 54, to make the chamber 54 be connected to a plunger inlet 57 via a center valve incorporated into the piston 51, moreover be directly connected to a plunger outlet 58. The pluner 48 is arranged in a connection conduit assigned to an outlet passage 23 for a driving wheel 2 from another brake circuit outlet 16, and moreover the inlet 57 is connected to the outlet 16, to connect the outlet 58 to a control valve, thereby connecting the control chamber of the plunger 48 to the inlet of a pressure limit valve 47. |
