Abstract

PURPOSE: In an intake device which has an air introducing device workable in deceleration provided in, to make it possible to compensate the number of idle revolution with a simple constitution when using an auxiliary machine by providing a mechanism which can introduce air compensating the idle revolution even at a start of the auxiliary machine to the downstream of a throttle valve.
CONSTITUTION: An air passage 11 is provided bypassing a throttle valve of an intake passage, and in the passage 11 is mounted a control valve 12. This control valve 12 presses a valve body 18 down through a diaphragm 22 and a rod 29 by a rapid increase of a negative pressure introduced into a negative pressure chamber 23 from a negative pressure passage 28 communicating to the downstream of the throttle valve, in a rapid deceleration at which the valve is closed rapidly, and opens. Then the bypass passage 11 is released to introduce a fairly large quantity of air to the intake passage 2. When a switch 46 is on following a start of an auxiliary machine, a plunger 45 of an electromagnetic change valve 44 communicates a negative pressure passage 40 to an intake passage in the downstream of the throttle valve to introduce negative pressure to a negative pressure chamber 37, by which a diaphragm 36 is moved downward to open the valve body 18 in the same manner as above.
