ABSTRACT:
A pressure regulating device regulates the pressure of a flowing medium and includes a stationary member. A movable armature is disposed axially from the stationary member for moving axially in relation to the stationary member. A coil is disposed about the stationary member and the armature and through which curernt flows for generating magnetic flux to create an attractive force to move the armature in relation to the stationary member. A housing is disposed about the coil and the stationary member and the armature for encasing the armature and the coil and the stationary member. At least one aperture is formed in the housing to allow a fluid medium to enter and exit the housing and to contact the armature. A means bleeds a portion of the fluid medium based on the current to the coil to control the output pressure to predetermined levels.
