Apparatus for adjusting simultaneously fluid pressure in a plurality of pressure vessels comprising a compressor. Communicating with the compressor through a relay valve is a manifold. A plurality of hoses communicate with the manifold and are connected simultaneously to the valve stems of a plurality of tires through respective valve stem connectors. The relay valve is normally opened for the flow of fluid under pressure from the compressor to the manifold. The relay valve is controlled through a regulator to close when sensing a preselected back fluid pressure from the tires through the manifold. Under-inflated tires will receive fluid under pressure from the compressor through the relay valve and the manifold. When the tires reach a preselected fluid pressure, the relay valve senses the tires reaching the preselected fluid pressure and the relay valve closes to shut-off the flow of fluid under pressure from the compressor through the relay valve. Overinflated tires will have fluid under pressure flow from the tires through the manifold and to the relay valve. When the tires reach a preselected fluid pressure, the relay valve senses the tires reaching the preselected fluid pressure and the relay valve closes to shut-off the flow of fluid under pressure from the manifold to the relay valve. Through the use of a manifold, the fluid under pressure will be equalized and balanced in each of the tires communicating with the manifold.
