Abstract
A spool valve includes a valve housing and a spool. The spool is slidable in an axial direction in the valve housing. A linear solenoid drives the spool against a spring. The valve housing has a feedback chamber to apply a force to the spool, an input port to receive a hydraulic pressure, an output port to produce an output pressure according to an axial position of the spool, and an drain port to exhaust oil to an outside. The spool valve has multiple supply paths to cause oil to flow from the input port to the output port and/or multiple exhaust paths to cause oil to flow from the output port to the drain port.
