ABSTRACT:
A pressure control device, preferably for use in a control system of an automatic transmission of a motor vehicle, is shown as having a solenoid motor assembly the armature of which, through a cooperating servo orifice, is effective for varying the magnitude of pressure of a fluid medium acting upon a spool slave-like valving member. The spool valving member has at least two cylindrical axially spaced valving portions with one of such valving portions having a diametrical dimension substantially greater than that of the other of the at least two cylindrical axially spaced valving portions.
