1. Controlable pressure regulator consisting of a diaphragm pressure regulator and a solenoid operator fixed to it and including adjusting means for the maximum and minimum outlet pressure characterized by the following features : a) a compression spring (10) pressing the diaphragm (4) of the pressure regulator in closing direction of the pressure regulating valve (3, 5) abuts against a movable rod (12) ; b) the rod (12) extends through the hollow cylindrical internal space of the energizing coil (13) of the solenoid and carries a movable armature (20) ; c) in a tubelike extension (16) of the coil form (14) a hollow screw (29) is screwed in at the side opposite diaphragm (4), with said rod (12) extending through the hollow screw (19) and the front surface of said hollow screw (19) forming an adjustable abutment for said armature (20) ; d) screwed unto the free end of the rod (12) is an adjusting nut (30), cooperating with a stationary stop and limiting the movement of the rod (12) in the direction to the diaphragm (4). |
