Compartmentalized fluid tank

摘要

A compartmentalized tank divided into a plurality of compartments are fluidly connected to a filling chamber wherein the filling chamber has an overflow fluid passage to each of the plurality of compartments and a fluid channel elevationally below the overflow fluid passage which conducts fluid flow during filling of the compartments but does not conduct fluid flow between the compartments when the tank is improperly oriented. Each of the plurality of compartments may include an orientation restrictive air vent, such as one formed by an elongated air channel positioned to reduce the loss of fluid in the event the tank is tipped on its side. The fluid channel has a plurality of orifices for conducting fluid flow from the filling chamber to the plurality of compartments which prevent fluid loss when a compartment is damaged. In another embodiment, the tank includes a supply line and a return line in each compartment. The fluid flow in supply lines and return lines may be controlled by a valve to prevent improper siphoning or leakage when the tank is damaged or improperly oriented.
