Pressure regulator

A pressure regulator continuously actuates the relative axial position and the tangential position of an armature relative to a valve body into the desired position so as to deliver a fluid at a constant pressure. The tangential position of the armature is determined in response to an electrical excitation of a coil resulting in a change in the magnetic forces applied to the armature. The axial position of the armature is adjusted in response to changes in the control pressure. The armature has a plurality of ports which enable fluid to enter and leave therefrom. The valve body has a plurality of ports in fluid communication with the armature ports. The armature has two elongated prongs. A compression spring is generally centrally disposed within the electromagnetic compartment of the armature. One end of the spring is secured to the armature and the other end of the spring is secured to the regulator housing. The armature is movable rotatably relative to the regulator, the spring resisting the rotational movement of the armature. The armature is movable axially relative to the regulator, the spring resisting the axial movement of the armature. A washer is positioned within the housing and about the armature. A flux path is generated through the washer, the housing, and the armature as the electrical current is varied. The rotational position of the armature relative to the washer is varied in response to the change in the current.
