发明名称 SINGLE-CYLINDER INTERNAL COMBUSTION ENGINE
摘要 A single-cylinder internal combustion engine comprising a crankshaft running on tapered-roller bearings in the front walls of the crankcase and a vane-type oil pump for the supply of oil to the connecting-rod bearing at the crankpin of the crankshaft, consisting of a rotatively driven ring with a front-end annular groove whose depth diminishes to zero from a point of maximum depth as far as an opposite peripheral point and wherein an elastic pin engages dividing the space defined by the annular groove and an adjacent stationary abutment into a suction chamber impinged upon by oil and a delivery chamber, the latter communicating via an oil drainage hole and oil ducts in the crankshaft with a crossbore of the crankpin ending in the connecting-rod bearing.
