DIESEL EXHAUST FLUID SYSTEMS

摘要

A diesel exhaust fluid system for use on a diesel-powered machine, including a storage tank adapted to store diesel exhaust fluid, a receiver, and a shut-off valve. The receiver is disposed in selective fluid communication with the storage tank and is adapted to receive diesel exhaust fluid. The shut-off valve is interposed in fluid communication between the storage tank and the receiver and has: a first position wherein diesel exhaust fluid can flow from the receiver to the storage tank, and a second position wherein flow is interrupted from the receiver to the storage tank. The shut-off valve moves from the first position to the second position in response to predetermined accumulation of diesel exhaust fluid in the storage tank.
