Abstract
A directional control valve is composed of a cylinder and a spool located therein so as to be slidably shiftable. The cylinder is formed to have a first input port, a second input port and a control port to which hydraulic fluid is supplied from a fluid pump; a first output port for supplying hydraulic fluid for clutch operation to a power-disconnection clutch, and a second output port for supplying hydraulic fluid for lubrication to the clutch. Positioning of the spool is shiftable between a first position wherein the first input port and the first output port are communicated, and a second position wherein the second input port and the second output port are communicated, according to hydraulic pressure via the control port.
