Abstract
The floating control valve of a vacuum operated booster has a recess or groove and a smaller steel washer which allows the seating portion of the control valve to seek its own plane. The insert is linearly aligned with the air valve seat. The outer portion of the control valve aligned with the vacuum valve seat on the power piston is not supported by the steel insert. The groove is positioned radially between the portions of the floating control valve engaging the two seats and may be on either the front or the rear side of the floating control valve.
