摘要 |
An accumulator piston for an automatic transmission. The piston comprises two components, the first and second being cup elements welded together with their closed ends in abutting relation. The lower cup includes a curled back portion with a radial flange having an axially extending bi-directional oil seal thereon, and spaced apart recesses in the curled back portion to permit oil to flow therein. The upper cup includes a radial flange of reduced diameter compared to the lower cup flange. The flange also has a lip seal thereon. The piston is spring-loaded and moves up and down in a bore and counterbore in response to fluid flow on either side of the piston to absorb shifting shocks. |
