<p>PURPOSE:To use a current to not only operate a switch-on solenoid valve but also control the set point of a servo pressure regulator by using a single solenoid operating device, normal springs, and other elements. CONSTITUTION:A solenoid 2 is provided which consists of a coil 9, a magnetic core 8, and an armature 7 and acts upon valve shafts of switch-on valves 31 and 33 together with the armature 7 on the one side and acts upon a pin 16 provided with a supporting member 15 of a control spring 12 facing a diaphragm on the other side. An armature reset spring 64 is provided which has a fixed supporting base in one end and is engaged with the armature after the armature is moved by enough stroke to open switch-on valves 31 and 33. Thus, a simpler controller is obtained which is easily adapted to operation conditions different from each other of loads connected to the controller.</p> |
