Abstract

PURPOSE: To reduce friction and to obtain stable characteristics in a valve having a moving coil type electric driving part by having a coil bobbin supported by leaf springs.
CONSTITUTION: One end of each leaf spring 18 is fixed to each terminal 8 and the other end is fixed to a bobbin 16, both ends of the windings of a coil 15 being electrically connected to each leaf spring 18 where it is fixed to the bobbin 16 respectively, said leaf spring being of approximately U-shape and having a small spring constant to permit easy axial movement of its moving end at the bobbin 16 side relative to its fixed end at the terminal 8 side and at the same time having a rigidity in the radial direction to support the bobbin 16 at the approximate center of a gap 14. Thus, very stable relationship between the electric current and the secondary pressure is obtained.
