Abstract:
A damped piston assembly is configured for use in a vehicle anti-lock braking system pump includes a piston, an insert and an elastomeric annular element. The piston has an axial cavity in a piston end portion. The insert has a cylindrical portion slip fit to the axial cavity of the piston. The insert also has a lip at an insert end portion with a diameter larger than the axial cavity of the piston and less than or equal to an outside diameter of the piston. The an elastomeric annular element is positioned between the lip of the insert and the end portion of the piston. The elastomeric annular element defines a gap between an end of the cylindrical portion of the insert and a bottom of the axial cavity in the piston when the piston is in an unloaded condition.
