US Patent 7779872 Service unit for replenishing service fluids

A service unit for use in replenishing and/or maintaining service fluids in a vehicle has a unit, such as a driving engine, with at least one service element, such as fill nozzles, and a collecting pan that at least partially encompasses the service element. To ensure the convenient replenishment or maintenance of service fluids, a protective drip cover is attached to the collecting pan. The protective drip cover can be shifted from a non-deployed position to a protective position, in which it projects at least partially beyond the collecting pan.
