Abstract:
A fluid reservoir for removable connection to a fluid system in a vehicle, said fluid system defining a fluid path through which a fluid flows, said reservoir comprising:a container defining a fluid receiving interior space and having a flow aperture, said container being constructed to be removably connected to said fluid system of said vehicle to allow for fluid communication between said interior space of said container and said fluid path via said flow aperture; and a valve mounted to the container at said flow aperture, wherein said valve substantially prevents said fluid in said interior space of said container from flowing out through said flow aperture when an exterior portion of said valve is exposed to ambient air, and wherein said valve is a pressure-activated valve that allows said fluid to flow from said interior space into said fluid path via said flow aperture only if a pressure within said interior space exceeds a pressure outside of said interior space by a first predetermined amount, and wherein said first predetermined amount is greater than a pressure across said valve when said container is full of fluid and said flow aperture is exposed to ambient air.
