ABSTRACT:
A pressure regulator includes a valve urged by a spring and a plunger in connection with the spring to adjust the tension of the spring. The plunger has a transverse pin engaging with a camming face of a sleeve around the plunger. The camming face lies in a plane inclining a radial plane of the plunger and causes the plunger to move axially when the transverse pin moves along the camming face.
