초록

A fluid control device for an electronic transmission is provided and includes a transmission spool valve and a proportional variable force solenoid valve disposed in a common housing for controlling the pressure of a fluid supplied to a first end of the transmission spool valve in a direction opposite to the biasing force of a coil spring. The variable force solenoid valve varies fluid pressure on the first end of the spool valve in proportion to the current level of the electric signal so as to control movement of the spool valve in a manner to regulat...
