Abstract
A brake force generator for a motor vehicle brake system, comprises a displaceable force input element connected or connectable to a brake pedal, a control valve actuable in accordance with a displacement of the force input element, a chamber arrangement disposed in a booster housing and controllable by the control valve and comprises at least one vacuum chamber and at least one working chamber, which are separated from one another by at least one movable wall connected to the control valve, and a force output element for supplying a brake force to a downstream brake system, wherein the control valve with the force output element is biased by a resetting spring into a normal position, wherein the resetting spring is supported by its one end against the control valve. In this brake force generator, for improving the assembly properties it is provided that a support ring is provided, against which the resetting spring is supported by its other end, wherein the support ring may be brought into supportive interaction with the booster housing.
