<P>PROBLEM TO BE SOLVED: To prevent breakage of a supply pump 3 due to freezing of reducer by preventing the reducer from remaining and freezing in the supply pump 3 after stop of an engine in a reducer supply device 1. <P>SOLUTION: The reducer supply device 1 is provided with an air pump 21 blasting air to the first gas phase part 20, a first valve device 22 opening and closing the first gas phase part 20 to and from atmosphere, a liquid level detection sensor 25 provided at an equivalent position with a suction port 17 of the supply pump 3 and installed on the first tank 14. Consequently, first liquid level 28 can be lowered to extract reducer from the supply pump 3 by starting an air pump 21 to pressurize the first gas phase part 20 when the engine stops and supply of the reducer becomes unnecessary. Consequently, breakage of the supply pump 3 due to freezing of the reducer can be prevented by preventing the reducer from remaining and freezing in the supply pump 3 after engine stop. <P>COPYRIGHT: (C)2008,JPO&INPIT |
