ンバルブ構造。 In the lock-up modulation valve structure of a torque converter, the spool is actuated by the load piston hydraulic pressure corresponding to the main relief hydraulic pressure introduced into the input port and the spring force, and pressure oil is supplied from the output port to the lock-up clutch side. ,
At the output port, there is an outflow flow force F, which is composed of a spool and a valve body, and which offsets the inflow flow force Ff1 generated in the spool.
A lock-up modulation valve structure for a torque converter characterized by being provided with a throttle that generates f2 .
