Brake circuit / Brake device and pressure control method that controls boosting via a suction valve specially connected to the wheel brake.

摘要

PROBLEM TO BE SOLVED: To provide an operating device for a vehicle braking device capable of more accurately controlling by designing a valve so as to have a large cross-sectional area, that is, a small flow resistance, without the need to use a PWM method. .. SOLUTION: The first piston / cylinder unit is provided, and at least one working room of the first piston / cylinder unit has at least one hydraulic conduit and a suction valve or a switching which opens at least in a no-current state. In those connected to the wheel brake via a valve device having a valve and equipped with a controllable pressure source to supply a pressure medium to the wheel brake, the control device boosts the pressure, volumetric control ( It is controlled via a suction valve by ΔV) and / or time control (Δt), and the inner chamber or mover chamber of the suction valve is connected to the brake circuit to which the brake circuit belongs via a hydraulic conduit. The valve seat outlet is characterized by being connected to the wheel brake to which it belongs via a hydraulic conduit. [Selection diagram] FIG. 1a
