摘要

A valve arrangement having a housing with an inlet for pressurized fluid and an outlet. A chamber is provided in the housing having a flexible diaphragm therein dividing the chamber into a control chamber and a pressure chamber. The pressure chamber and the control chamber are each connected in fluid circuit with the pressurized fluid supplied to the inlet through a constant cross section throttle opening. An analogue pressure regulator is provided for maintaining the pressure of the pressurized fluid in the control chamber constant independent of pressure variations in the pressure of the pressurized fluid. The analogue pressure regulator includes a control opening providing fluid communication from the control chamber to the outlet and a pivotally supported armature movable into and out of blocking relation with the control opening. A resilient mechanism is provided for resiliently biasing the armature so that its effective weight adjacent the control opening is approximately nil and is generally in a floating relation relative to the control opening so that pressure variations in the pressurized fluid will effect a pivoting of the armature and a consequent maintaining of the pressure in the control chamber constant. An electric magnetizing coil is mounted on the housing in magnetizing relation to the armature.
