Patent ID: 8376088

Claim:
A twin lubrication oil tank filling system with a single oil fill port that prevents overfilling of both a primary oil tank and a secondary oil tank, comprising: a float valve for the secondary oil tank to close oil flow into the secondary tank when the lubrication oil reaches a full level in the secondary tank; a gravity fill system comprising an oil diverter that diverts flow of the lubrication oil from the single oil port over the float valve for the secondary oil tank; a float valve for the primary oil tank to close oil flow into the primary oil tank when the lubrication oil reaches a full level in the primary oil tank; and a baffle plate that supports the float valve for the secondary oil tank and the float valve for the primary oil tank, collects the lubrication oil that spills onto the float valve for the secondary oil tank after the float valve for the secondary oil tank closes and directs the oil flow that the baffle plate collects to the float valve of the primary oil tank.
