An electric vacuum pump applied to a vacuum boosting brake system is provided. The pump has a water containing capacity that is greater than a backflow water capacity of an internal space defined in a pump housing which forms vacuum pressure. The pump includes a watertight chamber that is coupled to an exhaust port of a pump housing.

A pneumatic brake booster for a hydraulic motor-vehicle brake system, including a booster housing, having a front and a rear housing shell, and at least one connecting pin, which is arranged in the booster housing such that the at least one connecting pin extends axially parallel to the center axis and which supports the booster housing from the inside by two supporting formations and which protrudes through the booster housing from the inside to the outside on at least one side by an end segment. In order to ensure simple intermediate handling of the brake booster before and during the assembly of the brake system and to improve the durability and corrosion resistance, the housing shells are arranged in such a way that the housing shells are each connected to the connecting pin such that the housing shells are secured against being axially moved apart from each other.

A brake boost assist system for use with a master cylinder of a motor vehicle braking system, includes an inductive sensing system. The inductive sensing system has sensing devices carried on an input member and an output member, where the input and output members are coupled to respective ones of an input rod and an output rod of the brake boost assist system. Movement of the input and output members relative to one another, and relative to a fixed element of the inductive sensing system positioned within the brake boost assist system, enables an accurate estimation of the distance of a pedal gap which separates faces of the input and output rods. The accurate estimation of the pedal gap distance enables a more accurate determination to be made of the braking force required for any given pedal stroke input by an operator of the vehicle during a braking action.

This negative-pressure type booster device improves operation feeling for a driver at the time of a sudden braking operation. A valve body is provided with a flange part which extends in the radially outward direction from a front section of the valve body, and a plate is provided with a locking part which comes into contact with the flange part so as to restrict a movement in the axially forward direction relative to the valve body.
