Tapered Noise Attenuator For Anti-Lock Braking System
US Patent:
5921636, Jul 13, 1999
Filed:
Jun 13, 1997
Appl. No.:
8/874748
Inventors:
Christopher J. Roberts - Canton MI
Assignee:
Kelsey-Hayes Company - Livonia MI
International Classification:
B60T 1704
US Classification:
303 87
Abstract:
An attenuator for a hydraulic control unit of a vehicular braking system includes a hollow cylinder mounted in a bore of a housing. An end cap closes an outer end of the cylinder and does not extend beyond an outer wall of the housing. The cylinder and end cap define an interior chamber having an inner diameter tapered toward the end cap. An orifice is formed in the cylinder to permit fluid to exit the tapered interior chamber. An elastic core piece is fitted into the tapered interior chamber and substantially fills the volume of the chamber. An annular clearance is provided between the core piece and the cylinder. An inlet passage formed in the housing delivers fluid to the chamber. Fluid passes about the core piece to the orifice to reach the an outlet passage formed in the housing. Clearance between the core piece and the cylinder provides a streamlined path for fluid traveling from the inlet passage to the outlet passage, thereby decreasing fluid turbulence and aeration found in prior art attenuators.
