Direct-coupled controller of fluid transmission in automatic speed changer for car

Abstract

Abstract PURPOSE:To prevent deterioration of power performance and vibration by controlling the inner pressure of fluid transmission such that it will drop as the engine output increases. CONSTITUTION:A pressure maintaining valve 36 having a valve body 36a being energized to the open side by the inner pressure of fluid transmission T while to the close side by means of a spring 37 is provided in the way of an oil path communicating between the fluid transmission T and an oil tank R. A conduit 142 for feeding the fluid pressure representative of engine output is coupled to the pressure function chamber 141 of said valve 36. Consequently the inner pressure of fluid transmission T can be controlled to drop as the engine output increases. As a result, splitting of power from the fluid transmission T can be controlled in accordance to the engine output resulting in prevention of vibration or deterioration of power performance.
