摘要： PROBLEM TO BE SOLVED: To evade interference to other component to facilitate mounting. SOLUTION: This solenoid valve system 1 controls a current value supplied to a coil 20 to regulate driving force by which a spool 40 is pushed along the anti-linear solenoid 10 direction by a linear solenoid 10, and regulates hydraulic pressure of a hydraulic fluid flowing out from an output port 34. The hydraulic pressure of the hydraulic fluid flowing out from the output port 34 decreases in proportion to the current value supplied to the coil 20. A relation r2>=r1 is satisfied, where r1 represents an outside diameter of solenoid driving part 10, and r2 represents an outside diameter of a cylindrical part 32 of a valve housing 31. An outside diameter of a flange part 39 of the housing 31 is equal to the outside diameter of the cylindrical part 32 or less. Since the outside diameter of the solenoid driving part 10 is equal to the outside diameter of the housing 32, the whole solenoid valve device 1 is stored, for example, in a storage hole of a same diameter formed in a body of a hydraulic controller of an automatic transmission.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve miniaturizing the body, reducing the number of components, and reducing the assembling man-hours and manufacturing costs. SOLUTION: A non-coating part 13a is formed in a spool 30 side end face of a plunger 13 so that a position of the spool to the feed current value in coil energization is prevented from being dispersed without any relation with the dispersion of the film thickness of the coating film 130. The output pressure of hydraulic oil is prevented from being dispersed relative to the feed current value so as to enhance the accuracy of hydraulic control. The non-coating part 13b is formed in the counter-spool side end face of the plunger 13 so that the assembling of the plunger 13 is facilitated so as to reduce the assembling manhour. This constitution can also eliminates the post-processing such as polishing and wrapping finish for controlling the coating film thickness and securing the accuracy. The manufacturing cost can be thus reduced.
