<p>The pressure regulating valve (1) has high-pressure inlet (2), low-pressure outlet (3), valve seat (5) and displaceable valve piston (6) cooperating with valve seat. A spring (7) pushes the valve piston from the valve seat in response to operating force. A magnetic coil (8) is provided in the valve piston, so as to provide clamping force or actuating force to the valve piston, when magnetic coil is traversed by electric current. The path between high-pressure inlet and low-pressure outlet is opened by valve piston, when clamping force is made to act on valve piston.</p> |
