    摘要： A brake apply system includes a power booster in which, when released and at-rest, a leg of a stop engages a clip and an extension of a valve body engages the clip so that an annular rib of the valve body is axially spaced away from the stop by a distance G. At the same time, a first valve seat is engaged with a first annular valve element closing a pressure supply conduit off from a variable pressure chamber and a second valve seat is spaced away from a second annular valve element by a distance T, opening the variable pressure chamber to an atmospheric pressure chamber. When the power booster is applied, the second valve seat moves the distance T and engages the second annular valve element closing the variable pressure chamber off from the atmospheric pressure chamber and the first valve seat separates from the first annular valve element opening the pressure supply conduit to the variable pressure chamber. The stop moves against the annular rib of the valve body so that when the pushrod is initially released the second annular valve element moves away from the second valve seat a distance equal to G+T. A pressurized air supply communicates with the power booster and includes a compressor and a dryer. When the compressor is turned off a solenoid valve opens and a quantity of dry air contained in a regeneration reservoir passes through the dryer, regenerating the dryer.

    摘要： A power booster includes a housing with a rear housing section and a front housing section defining an internal cavity. A housing wall separates the internal cavity into a first chamber and a second chamber with an opening formed in the housing wall, wherein it is desirable to extend a component through the opening. A tube has an end secured in the opening in the housing wall. The tube's end includes a radially directed wall extending from the end of the tube that extends to an axially extending wall positioned concentrically with the tube and terminating with an outwardly turned segment. The axially extending wall is positioned within the opening in the housing wall with a seal positioned between the axially extending wall and the housing wall wherein the distance between the front housing section and the rear housing section is minimized, by extending the component through the tube.
