  • Oil control system for piston-type airplane engines
    Patent number: 4329952
    Abstract: A manually-operated valve is associated with the oil tank of an airplane's lubrication system so that oil can be circulated directly from the oil outlet of the engine to the oil inlet of the engine until the oil becomes warm. The manually-operated valve can then be repositioned so as to mix oil from the oil outlet of the engine with the oil contained in the oil tank, then supplying the mixed oil to the inlet of the engine. Provision is also made for directing oil from the oil outlet of the engine to the manually-operated valve after it has been cooled by the oil cooler, the mixing action then being achieved with the cooled oil.
