The present invention provides at leastone venturi (26) for creating a vacuum through a flow of pressurized air. The presentinvention selectively provides a flow of pressurized air from a pressurized air source tothe vacuum creating means and selectively provides a flow of pressurized air to thevacuum responsive device. A last function valve (50) communicates with the selectiveproviding of pressurized air to maintain the operating condition of the vacuum responsivedevice during the loss and resumption of power.
