PURPOSE:To reduce lubricant consumption at low loads so as to secure the necessary amount of lubricant at high loads by restricting the delivery of a lubricating oil pump for two cycle engines for engine speeds less than a certain value, and also by increasing an increasing rate of delivery for engine speeds equal or more than the certain value. CONSTITUTION:One end of an outer wire 8 is connected with a delivery adjusting lever 7 of a lubricating oil pump 4 for two cycle engines via a holder 16, and the other end of the outer wire 8 is fixed by a receiver 15. The other end of an inner wire, one end of which is connected with an accelerator grip to be inserted into the outer wire 8, is connected with No.2 control lever 9 which is driven by a pressure actuating device 11. When engine speeds are found to be a certain value or more by the detected value by an engine speed sensor 37, the positive pressure of an accumulator 12 is introduced to a positive pressure chamber 22 of the pressure actuating device 11 via a solenoid change- over valve 13 for rotating No.2 control lever 9 clockwise so as to increase a rate of delivery. |
