<p>A master/slave discharge valve assembly for pressurized fluid containment systems includes a primary valve chamber, for connection to a fluid pressure source, formed by an eccentrically disposed first longitudinal bore and a secondary valve chamber defined by a second bore generally parallel to that of the primary chamber, communicating at one end with the primary valve chamber and a the other end with a discharge port. A displaceable primary valve member is positioned within the primary valve chamber. A slave valve member and an actuating piston are to open the slave valve member and permit a holding portion of pressurized fluid to vent to the atmosphere, thereby permitting the pressurized fluid to open the first valve member and allow pressurized fluid out the discharge port. A master/slave valve assembly according to the invention is of lower cost to manufacture as well as simpler and sturdier in construction than known valves for carbon dioxide fire suppression systems.</p> |
