ABSTRACT:
An I.C. engine lubrication system comprises a gerotor pump set driven by a gear meshed with another gear on the crankshaft (FIG. 1). This enables pump diameter to be selected for minimum power absorption as compared with prior art arrangements where the gerotor surrounds the crankshaft, and also simplifies pipework particularly on the delivery side of the pump.
