Abstract
A tombstone assembly within a vessel utilizes disk control valves for conlling the flow of seawater to torpedo tubes. The disk control valves have disks abutting flow ports on a vertical plate within a tombstone. The vertical plate separates an impulse chamber from a plurality of tube chambers. The tube chambers hold the torpedo tubes. The disks control the flow of seawater between the impulse chamber and the tube chambers. The seawater is initially pumped from outside the vessel through a water cylinder into a lower impulse tank then into the impulse chamber of the tombstone. The disk valves then control the flow of the seawater to the tube chambers.
