ABSTRACT:
An improvement of a variable pressure passage formed in a valve body of a booster to provide a communication between a valve mechanism and a variable pressure chamber is disclosed. The variable pressure passage comprises a pair of radial bores formed in the valve body and a plurality of axial grooves which provide a communication between the radial bores. This secures a sufficient channel area for the variable pressure passage, which then includes a plurality of flow paths. Accordingly, sound which is produced upon actuation of the booster as the atmosphere flows through the variable pressure passage can be reduced without degrading the response of the booster upon actuation.
