A power booster comprises a rear housing section and a piston. An inner bearing is disposed around the piston, and is adjustable relative to the rear housing section to translate the piston. A method of setting an axial dimension of the power booster is also provided.

Vacuum booster rear bearing

The problem of providing air from a vehicle engine compartment to a breather port of a vacuum booster mounted on a wall separating the engine compartment from the passenger compartment is solved by adapting the wall to provide an air passage, when the rear wall of the booster is bearing against the wall.

Vacuum booster air intake via engine compartment breather passage

A power booster comprises a housing, a tube, and a seal. The housing includes a front housing section, a rear housing section, and a divider. The tube is mechanically fastened proximate the rear housing section and generally stationary relative to the rear housing section, with the seal between the divider and the tube.

Power booster sealing mechanism

An airvalve assembly for a brake booster includes first and second members movable relative to each other to allow the passage of fluid, and a clip. The clip engages one of the first or second members, and has a spring arm which engages the other of the first or second members to normally position the first and second members relative to each other.

Airvalve assembly for a brake booster

This brake booster comprises an enclosure ( ), a diaphragm ( ) dividing the enclosure into a front chamber ( ) connected to a source of vacuum and a rear chamber ( ), a piston ( ) that can move axially in the enclosure and on which the diaphragm is mounted, a plunger ( ) mounted so that it can move axially in the piston between a forward unstable braking position and a retreated stable position of rest, and a valve ( ) intended to collaborate with seats ( ) on the piston and on the plunger. The or each seat ( ) on the piston ( ) is formed on the edge of a passage ( ) allowing the said chambers ( ) to communicate.
