<p>PROBLEM TO BE SOLVED: To obtain a large stable control pressure in a linear solenoid to an input current applied thereto and improve its responsiveness by preventing a hysteresis and a radial load from occurring in its thrust generation part. SOLUTION: A linear solenoid comprises a pressure regulating valve part 1 in which a valve element is held slidable by the pressing force of a single elastic member, and a thrust generation part 2 for generating thrust by means of a shaft 23 and transferring it to the pressure regulating valve part 1. The thrust generation part 2 is constituted of a moving-magnet type linear actuator 20 comprising two permanent magnets 22, which are inserted in three coils 21 arranged in line as well as are fitted on the shaft 23 so as to face each other at the same pole.</p> |
