摘要: A brake system has a brake booster secured to a dash panel which separates an engine compartment from a passenger compartment of a vehicle. A bracket off-sets the booster into the engine compartment from the dash panel. A cylindrical body has a flange on a first end located between the housing of the brake booster and the bracket. The cylindrical body has a partition wall located between the first end and a second end and a radial opening located between the partition wall and the second end. The partition wall has a central opening through which an input rod extends to provide a valve with an input force. An end boot, secured to the second end of the cylindrical body and the input rod, forms a resonant chamber within the cylindrical body. The radial opening provides unrestricted communication air from the engine compartment to the resonant chamber while the central opening forms an orifice to control the air flow from the resonant chamber into the valve body. The resonant chamber is of sufficient size to dissipate audible sounds produced by the flow of air through the orifice to the valve.
