PURPOSE:To feed the optimum lubrication oil without delay by suspending correction at the time when an engine load rises in case of correcting an oil adjusting means and the offset at the reference position of the electric actuator driving it. CONSTITUTION:A metaling oil pump 17 as for a lubrication oil feeding device is stored inside a housing 20 at its main plunger 21 and also stored in the one end part of the main plunger 21 at its auxiliary plunger 22. At the other end part side of the main plunger 21 in the housing 20 the control cam 25 controlling the reciprocating movement of the main plunger 21 as a lubrication oil adjusting means is arranged. A stepping motor 33 as for the actuator which drives the control cam 25 is arranged. In this case, at the time when the engine load rises during the specified correction operation period the operation correcting the offset at the reference position of the stepping motor 33 and control cam 25 is cancelled. |
