Claims

[Scope of utility model registration request]

(1) The fixed coil @ of the motor is energized to rotate the rotor ■ integrated with the valve stem ■, and the rotation is converted into linear motion of the valve stem by the screw ■ formed on the valve stem. In a proportional control valve that controls the flow rate by changing the gap between the needle valve ■ formed at the tip of ■ and the valve seat ■ in the valve body ■, the front of the male thread ■ provided on the valve stem ■ or Fix the pins [phase] and [phase] at the front and rear of the male screw ■, and fix the fixing holes [phase] at equal angles on the surface of the propulsion bearing 0. A large number of [phase]... are provided, and on the other hand, the stopper body [phase]
As, stopper 0. o and the insertion part ■ are integrally configured, and the insertion part ◎ of the stopper body is inserted and fixed into the fixing hole [phase] so that the axial positional relationship between the pin [phase] and the stopper 0 is a predetermined dimension. A proportional control valve featuring:

(2) The proportional control valve according to claim 1, wherein the stopper main body is a pin-shaped body.
