ABSTRACT:
An automatic air valve assembly for alternately delivering pressurized air to one of a pair of control ports of a reciprocal power unit comprises a valve body having a bore, a plurality of inlet, cylinder, and exhaust ports, with the inlet port adapted for connection to a pressurized air supply, and a valve spool movable between a pair of control positions. A pair of pilot valves are mounted upon the ends of the valve body to move the spool between its control positions. Each pilot valve is connected to a cylinder port and has a normally closed air signal port connected to opposite ends of the valve body respectively whereby a build up of pressure at one cylinder port momentarily moves a spring biased spool in one pilot valve to open its signal port, the spool in the valve body continuously and automatically oscillating.
