Technical Examples

A vacuum booster includes a housing defining a control volume in which a movable diaphragm separates the control volume into an apply chamber and a vacuum chamber. A power piston extends through and engages the diaphragm and has an axial bore containing a valve assembly that controls a diaphragm pressure differential across the diaphragm. The power piston drives an output rod in the forward direction. The output rod has a rearward portion exposed to pressure within the vacuum chamber and a forward face exposed to atmospheric pressure. When the pressure within vacuum chamber is less than atmospheric, a piston pressure differential across the power piston provides a return force in the rearward direction to the power piston.
