PERALATAN UNTUK OPERASI SUATU TRANSMISI

摘要

A transmission operating apparatus includes a booster for increasing the transmission operating force, and a buffer device for suppressing rapid shift-changes caused by a change in the load due to the damper action of a hydraulic damper mechanism. A by-pass is incorporated into the buffer to permit working fluid to flow into damper chamber by-passing an orifice when necessary. A sealing member having a sealing portion is interposed in the by-pass to seal the by-pass under normal conditions but is resiliently deformed releasing the seal when the working fluid flows into the damper chamber.
