Multi-fit Encapsulated Oscillation Dampener for Automotive Automatic Transmissions

Abstract

A dampener assembly includes a capsule housing an internal piston and spring, the spring positioned within and between both the piston and capsule. The capsule is generally cylindrical with an opening at a first end to accept the piston into an inner cylindrical channel of the capsule. A vent is positioned along a second end of the capsule to release pressure as the piston moves back and forth along the inner channel in response to fluid pressure in a transmission and counteracting force from the spring. The capsule is installed in either a reamed or unreamed bore and acts as a new bore. The dampener assembly is sealed to the bore by one or more elastomeric rings.
