Patent ID: 6860293

Claim:
A proportional variable pressure solenoid valve for controlling the pressure of a pressurized fluid in a hydraulic system in proportion to the current level of an electrical input signal, comprising: a movable valve for controlling the pressure of the pressurized fluid in the hydraulic system, the movable valve including: an inlet valve for controlling the flow of pressurized fluid into the solenoid valve; and an exhaust valve for controlling the exhaust of pressurized fluid from the solenoid valve; a solenoid for controlling the movement of the movable valve, the solenoid including: an armature spring biased at a first end and engaged with the exhaust valve at a second end for transmitting force in one direction for displacing the movable valve; the second end of the armature engaged with a diaphragm member in abutment with a suspension member; a flux member receiving the second end of the armature; a first suspension washer mounted at the first end of the armature and a second suspension washer mounted at the second end of the armature; and an electromagnetic coil for generating a variable electromagnetic field in response to the electrical input signal for moving the spring biased armature; and a common housing.
