Abstract

A hydraulically actuated regulating valve for a vehicle brake system includes a first fluid port, a second fluid port, and a control chamber. A longitudinally movable plunger with a sealing geometry is loaded with a spring force and held in an initial position by a compression spring. A pressure built up in the control chamber acts counter to the compression spring and moves the plunger with the sealing geometry from the initial position into an end position. The sealing geometry interacts with a valve seat which is positioned in a valve body in order to limit an effective pressure at the second fluid port to a predefined maximum pressure value. A fluid connection between the first and second fluid port is completely opened up to a corresponding vehicle brake system in a first end position of the plunger and is completely closed in a second end position of the plunger.
