Abstract
A four-way, poppet valve having a plurality poppet valve elements mounted on a poppet valve spool. The poppet valve spool is movable in one direction by a return spring to a first operative position, whereby one pair of the poppet valve elements are seated on a first pair of poppet valve seats to control the flow of pressurized air through the valve from a pressurized air inlet port and out through a first cylinder port and simultaneously to exhaust air entering a second cylinder port. A solenoid means having a floating pole piece is provided for moving the valve spool to a second operative position, whereby a second pair of the poppet valve elements are seated on a second pair of poppet valve seats to reverse the flow of pressurized air through the valve. The flow of exhausting air may be controlled by a pair of flow control valves.
