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 which ultimately provides a fluid medium to associated fluid medium receiving structure; a fluid medium flow restriction formed as of sintered metal enables the fluid medium to flow in and through the control device to thereby bring about purging of air and other gases from within said control device.
