Title: Controller for lock up clutch using rotary valve
Inventor: ANDO MASAHIKO
IPC: F16H45/02
Filed: 1987-06-12
Abstract: PURPOSE:To simplify a hydraulic circuit by selectively connecting a line pressure or drain to an oil passage through which a hydraulic signal is transmitted to a selecting valve by the rotation of a rotary valve and an oil passage through which oil is supplied to an automatic hydraulic servo for performing a speed change and releasing the engagement of the lock up clutch. CONSTITUTION:A lock up clutch selecting signal pressure is transmitted to the upper port of a lock up clutch selecting valve 12 through the oil passage (d) by a rotary valve 3. Thus, the selecting valve 12 is lowered so as to supply a secondary pressure in a lock up clutch ON circuit, thereby turning ON the lock up clutch. Conversely, the lock up clutch selecting signal pressure of an oil passage (d) is drained by the valve 3 so that the selecting valve 12 is lifted by the spring force of the selecting valve 12 and the line pressure of a lower port, followed by supplying a secondary pressure in the lock up clutch OFF circuit, thereby turning OFF the lock up clutch. Therefore, it is possible to reduce the number of valves.
