Fluid handling systems & multi-positionable valving arrangements for the use therein

摘要

A compact fluid handling system and multi-positionable valving arrangement for use therein wherein a plurality of fluid source means such, for example, as a plurality of fuel tanks or the like, are adapted to be interconnected with a plurality of fluid utilization means such, for example, as a plurality of diesel engines or the like, in such a manner that fluid contained in a selected one or ones of the plurality of fluid source means can be directed to all or selected ones of the plurality of fluid utilization means, and wherein excess fluid which is unused by the fluid utilization means can be returned to the particular source means from which it was supplied or, in certain instances, can be returned to fluid source means other than that from which it was supplied. Various embodiments of the invention are illustrated and described, generally in connection with a fluid control valve system of the type having one or more disk-type control elements, wherein the system might be employed on marine vessels or the like where the invention finds particularly advantageous, but not necessarily exclusive, use. More particularly, the invention pertains to improved, compact valving arrangements which permit establishment of simple, yet highly effective, seals in multi-port valves suitable for use in such systems. In the various embodiments illustrated it is possible to incorporate both the fuel delivery and fuel return functions in a single valve or two identical valves.
