Abstract

PURPOSE: To install a negative pressure responsive type control valve on the secondary air supplying passage in the contrivance for introducing secondary air by using exhaust pulsation.
CONSTITUTION: A control valve 2 is of negative pressure responsive type, a discoid valve body 8 is provided in a cylindrical valve box body 7 to have an inlet pipe 5 and an outlet pipe 6 conducted together in uneven parallel, a valve rod 9 to support a valve body 8 is connected to a diaphragm 10, the lower side chamber 11a of a diaphragm chamber 11 held and housed this diaphragm 10 is conducted through a nozzle 12 to a controlling and housed this diaphragm 10 is conducted through a nozzle 12 to a controlling negative pressure source 13 of a control valve 2, the diaphragm 10 is deviated in the direction of detaching the valve body 8 away from the valve seat 15. And it is to openingly and closingly controlled to the drive condition.
