Claims

[Scope of utility model registration request]

The valve body is formed with a sliding hole through which the drain passage and the pressure oil supply passage communicate with each other, and the valve body is fitted into the sliding hole so as to be slidable in the axial direction, and corresponds to the drain passage and the pressure oil supply passage. A spool has a land portion formed to throttle and open/close communication between the drain passage and the pressure oil supply passage depending on the position, an electromagnetic means for biasing the spool in one direction, and a screw screwed into one end of the slide hole. a closing member formed with a protrusion projecting from the valve body at one end; a spring member fitted between the closing member end and the spool end to bias the spool in the other direction; A pressure control electromagnetic spool valve comprising an engaging hole and a detent member that can be engaged with the outer periphery of a valve body in the rotational direction and is removably fitted.
