Abstract
A pressure reducing valve includes a first screw member on which a nut for adjusting the spring force of a pressure regulating spring travels, and a second screw member screwed into the first screw member and provided with a stopper for limiting the travel range of the nut at the tip. The second screw member can be displaced with respect to the first screw member along its length, so that the limiting range of the stopper against the travelling nut is adjustable.
