Abstract

589,256. Lubricating systems. BATEMAN, P. J. March 20, 1945, No. 7054. [Class 12 (iii)] A forced lubrication system for internalcombustion engines more particularly for aircraft comprises a pump circuit for passing hot oil, draining into the engine sump, to a cooler, an independent pump circuit for pumping to the engine parts requiring lubrication cooled oil taken from the sump adjacent the return pipe from the cooler or from a tapping to such return pipe, and an independent supply line for maintaining a constant quantity of circulating oil by allowing a flow of make-up oil to the sump from a remote tank or a return flow of excess oil to such tank. As shown an engine sump 1 is divided by a partition 16 having a small throughflow aperture 18 into a hot-oil portion 1h and a cooled-oil portion 1c, the latter having a cover 17 to prevent direct entry .of hot oil draining from the engine. A pump 2 draws hot oil from the portion 1h for delivery to a cooler 4 whence it passes to the cooled oil portion 1c for delivery to the lubrication points by an independent pumping circuit including a pump 11. Make-up oil from a storage tank 8 is fed by an independent line 9 to the hot-oil portion 1h when the level falls sufficiently to operate a floatcontrolled valve 7 while should the level rise, above normal the float-controlled valve diverts the delivery of pump 2 away from the cooler 4 back to the storage tank 8 so that excess oil is pumped back to such tank. The storage tank is located at the remote side of a fireproof bulkhead 10. The usual relief valves 6, 15 are provided on the delivery sides of the pumps 2, 11 and to prevent flooding from the storage tank 8 when the pumps are stopped a non-return valve 19 is inserted in the pipe line from the pump 2. The pumps are arranged on the bottom of the sump so that their inlets are always covered. The pumps are driven in tandem from the engine by the shafts 12h, 12c but are quite independent as to capacity and pressure and draw their supply independently of one another by reason of the through-flow passage 18 connecting the hot and cold oil portions 1h, 1c of the sump. If desired a separate pump reversible by the float may be used for the drawing off and returning of oil to the storage tank.
