Abstract: The present invention includes a system for providing an improved controlled airflow within a vacuum booster system. The system includes a vacuum booster assembly having a primary chamber and a secondary chamber, and an outer tube having a first end and a second end, the first end in communication with the secondary chamber of the vacuum booster assembly. The system additionally includes an airflow control assembly operably coupled to the second end of the outer tube, and an inner tube, concentric to the outer tube, having a first end and a second end, the first end operably coupled to the airflow control assembly, the second end in communication with the primary chamber of the vacuum booster assembly. In the system, air flows from the primary chamber of the vacuum booster assembly to the airflow control assembly within the inner tube and air flows from the airflow control assembly to the secondary chamber of the vacuum booster assembly within the outer tube.

Abstract: An improved method and apparatus for mounting a brake booster on a panel with an adapter are provided, through the use of a boot having a generally cup-shaped wall defining a flange for sealing a juncture between the brake booster and the adapter, a sealing lip for sealing a juncture between the boot and the adapter, and a hole for passage of the push rod, with the hole having a periphery for sealing the juncture between the boot and the push rod. The boot includes an air intake extending through the wall of the boot between the flange and the sealing lip.

Abstract: A collapsible push rod for a brake booster in a vehicle is provided, having first and second telescoping members, and retractable locking means for selectively locking the first and second members together against telescoping. During a frontal impact collision, the members telescope into one another to shorten the length of the push rod and compensate for rearward movement of the brake booster and forward movement of the driver. The push rod is operable in the collapsed state. The push rod is also re-settable after the collision, and includes features for returning the push rod to its normal un-telescoped length following the collision, if the push rod is not damaged in the collision. The retractable locking means includes an electrically actuated solenoid for selectively locking and unlocking the first and second members against telescoping, in response to an electrical signal applied to the solenoid.

Abstract: A lightweight spacer for mounting a vacuum brake booster on a panel provides integral flexible sealing lips to seal the interfaces between the panel, spacer, and booster. Integral retaining tabs are provided for holding the spacer in place on the booster during shipping and installation of the booster. Tubular inserts within the spacer are retained and cushioned against rattling by a thin web of material extending over the end of the insert.

Abstract: A pneumatic brake booster includes a generally cylindrical shaped piston. The piston has a first piston end and a second piston end and defines a chamber at the first piston end and a piston bore at the second piston end separated by an air flow aperture. The piston bore includes a plunger aperture located at the second piston end. A plunger includes a first plunger end and a second plunger end and is movable between first and second positions. The second plunger end is located within the plunger aperture. An air valve has a first valve end and a valve second end and is movable between first and second positions and defines a valve bore for receiving the first plunger end. A collapsing spring is located within the valve bore and is adapted to couple the plunger and the air valve. The plunger and air valve are spaced apart a first relative distance in response to the pneumatic brake booster being in a regular apply mode and spaced apart a second relative distance in response to the pneumatic brake booster being in a panic apply mode.
