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 current 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 flow valve is spaced axially from one end of the armature for moving independently of the armature to prevent parasitic forces from being transmitted by the flow valve to the armature.

A pressure regulating device for regulating the pressure of a flowing fluid medium, said device comprising: a stationary member, a movable armature means disposed axially from said stationary member for moving axially in relation to said stationary member, coil means disposed about said stationary member and said armature means and through which current flows for generating magnetic flux to create an attractive force to move said armature means in relation to said stationary member, housing means disposed about said coil means and said stationary member and said armature means for encasing said armature means and said coil means and said stationary member, aperture means for forming at least one aperture in said housing means to allow a fluid medium to enter and exit said housing means and to contact said armature means, flow valve means having first and second axially spaced ends being of a single diameter and one of said pair of ends being spaced axially from one end of said armature means for moving independently of said armature means to prevent parasitic forces from being transmitted by said flow valve means to said armature means; poppet valve means disposed axially between said flow valve means and said armature means for creating a restriction of fluid flow to said armature means; and biasing means disposed axially between said poppet valve means and said flow valve means for biasing said flow valve means axially away from said armature means to reduce oscillations between said armature means and said flow valve means.
