The role of the filter is to remove the dirt and oil from the front 3i1i, so the fine dust and oil from the front 3i1i must be removed (rather than being passed through). If the first hole becomes stuck, the above-mentioned problem will occur.In this case, it is possible to reduce the air cleaner's ability to remove 1y of dust, but in that case, the suction resistance will be added by 1jll.

In order to achieve the above-mentioned object [1], the present invention provides an on-off valve that is installed at the connection between the intake pipe and the warm air intake pipe of the engine air cleaner and operates under negative pressure, and a shut-off valve that is installed at the clean lead of the air cleaner. A negative pressure control valve that dilutes the intake negative pressure with the atmosphere and controls the operating negative pressure of the on-off valve. The gist of this is that the negative pressure control valve is disposed inside a Fu rJ letter case with a large capacity.

J゛ru. Nowadays, the minute pollution and oil in the atmosphere are removed by the thin filter installed in the filter case [1], so only the normal air flows in, which can prevent the valve body from sticking or the orifice. 1. No rips occur.

(At the second stage, the intake negative pressure is diluted to approximately atmospheric pressure, (-: + IE
'Since the negative pressure of 7a disappears, J- is applied to spring 7b.
When the on-off valve (3 goes down and closes the warm air intake pipe 6)
(, listen to the outside air introduction duct 1a. As a result, - "no'
Cold air from the outside world is introduced into the cleaner 2. In the above, even if the atmosphere that the valve body 12 hears and absorbs the negative L of the valve chamber 26 contains the fine dust particles A that have passed through the filter element 1-28 of the air cleaner 2, lυ
Even if it were, it would be filtered when it passes through the 17ill filter 17 of the remesh 7 and would be introduced as i'+'+ near 1 popularity. For this reason, valve 1 hole 12-1'-A
