Abstract
A proportional pressure control valve has a poppet including a control pin for seating against the seat and which is pressed into a generally tubular armature. One end of the armature proximal to the seat has an enlarged diameter and fits into a cup shaped recess of the housing in an extreme position of the poppet. A smaller diameter of the armature is journaled in a magnetic sleeve bearing at a distal end of the poppet and the control pin is journaled in a sleeve bearing at the proximal end of the popper. A plastic plug covers the distal end of the armature and an annular gap is created at the distal end of the armature bearing between the armature and the housing.
