PROBLEM TO BE SOLVED: To provide fuel supply equipment which does not require an oil separa tor as a separate part by preventing oil mist from entering in a pulse pressure actuation chamber while promoting separation of oil in a rocker arm chamber. SOLUTION: A fuel pump is driven by pulse pressure generated in a crankcase by communicating the pulse pressure actuation chamber of the fuel pump to the crankcase via a pulse pressure take-out chamber 40. A connection path 23 for connecting the crankcase and the rocker arm chamber 5a is provided from a cylinder block of the engine to a cylinder head 4. The rocker arm chamber 5a is divided to arrange the pulse pressure take-out chamber 40 apart from an end opening port 23a. COPYRIGHT: (C)2003,JPO
