摘要： In combination with a double-acting cylinder having pressure and exhaust ports, a cylinder control valve having a spool having a pair of control positions with pressure, cylinder and exhaust ports, and conduits between the valve cylinder ports and cylinder ports, and a source of compressed air connected to the valve pressure port, a safety control system which comprises a pilot-operated valve housing having a pressure port connected to the source of compressed air, a pilot port and a pair of cylinder ports connected to the cylinder conduits. A valve spool within said housing has first and second control positions with an operative device on the housing which normally biases the safety valve spool to a first control position pressurizing opposite ends of the cylinder and with the pilot port connected to the source of compressed air. A build up of pressure to the pilot port moves the safety valve spool to its second control position, blocking communication between the safety valve and the cylinder ports. The spool of the cylinder control valve has a normal central position blocking the conduits to the cylinder assembly ports. The safety valve spool is adapted to automatically return to its first position on disconnecting pressure from said pressure source, bleeding opposite ends of the cylinder.

摘要： 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.
