Abstract
A fast acting valve for use in a stored energy projectile launching system. he valve has an inlet port for connection to a storage energy device, an outlet port for connection to a launching tube and an intermediate chamber. The interior of the valve seat communicates with one of the ports through a plurality of apertures that permit liquid to transfer between the ports. A cylindrical valve lies inside the cylindrical valve seat and sealingly, slidingly engages the interior of the cylindrical valve seat. A microprocessor-based control system provides a controlled velocity profile transfer of the valve between a first position in which the valve seals the ports and a second position in which the valve clears the ports.
