Patent ID: 8857480

Claim:
A vehicle having multiple isolated fluid circuits configured to be filled through a first fill port, the vehicle comprising: a first fluid circuit disposed within the vehicle, the first fluid circuit having a first fill port; a second fluid circuit disposed within the vehicle; a conduit defining a fluid passageway between the first fluid circuit and second fluid circuit, the conduit including a valve, wherein the valve includes: a valve body; a plunger disposed within the valve body and configured to be depressed into the valve body by a user; wherein depression of the plunger causes the valve to close such that a portion of the plunger impedes fluid flow through the fluid passageway; wherein the plunger includes a ridge that mechanically inhibits the valve from opening once the plunger is depressed into the valve body; wherein the first and second fluid circuits are fluidly coupled via the passageway when the valve is open, and the first and second fluid circuits are fluidly isolated when the valve is closed; and wherein the first and second fluid circuits are configured such that fluid provided via the first fill port enters both of the first and second fluid circuits when the valve is open.
