<p>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 which ultimately provides a fluid medium to associated fluid medium receiving structure; a spring normally urges the armature toward the servo orifice and an adjustable spring seat is operatively engaged with the spring; the adjustable spring seat is formed of at least two pieces.</p> |
