23 TITLE FLUID DISTRIBUTION SYSTEM HAVING NOISE REDUCTION MECHANISM ABSTRACT OF THE DISCLOSURE A fluid distribution system, such as a valve, comprises a housing having a chamber which has a plurality of acoustic modes. The acoustic modes are excited when fluid flows through the chamber. An inlet passage and an outlet passage are disposed in fluid communication with the chamber. A plate is disposed in the inlet passage. A plurality of orifices are formed in the plate. The orifices conduct fluid from the inlet passage to the chamber and reduce the coupling between the flow of fluid through the inlet passage and the acoustic modes of the chamber. With this arrangement, the acoustic modes of the chamber and the resonance frequency of each of the orifices are substantially unexcited by the flow of fluid through the orifices. 23
