Abstract
Since an output port is formed at a front end portion of a sleeve, an electromagnetic valve is arranged in series with a control valve. Thus, a system becomes small, and it becomes easy to attain a mounting space. Further, since a feedback chamber is formed in the vicinity of the linear solenoid, it is possible to install a spool after the sleeve is attached to the linear solenoid. Thus, unidirectional assembling becomes possible, and the number of assembling steps is decreased. Furthermore, since a small-diameter land is provided in the spool at a side of the linear solenoid, a small-diameter inner wall for slidably guiding the small-diameter land is concentrated to one place at the side of the linear solenoid. Thus, forming a small-diameter hole in the sleeve becomes easy, and forming accuracy is improved.
