ABSTRACT:
A screw member is screwed into a spool which is axially movably inserted into a housing. The opening of the throttling portion of a variable throttle valve is varied according to the axial shifting of the spool according to the rotation of the screw member. The centerline of the screw member is eccentric to the centerline of the spool. The eccentricity prevents the spool from rotating together with the screw member.
