Abstract

PURPOSE: To simplify the structure of a control valve, by changing the force of a spring carried on a valve body provided in a negative pressure control valve for EGR system, in accordance with rotation of fuel injection pump.
CONSTITUTION: A casing main body 1 of a negative pressure control valve comprising two covers 2, 3, and a diaphragm is holded between the both covers. In a diaphragm chamber 6 of one side, there are provided a negative pressure intake port 10, valve member 19 adapted to open and closs the prot 10, and negative pressure take-out port 11. In an atmosphere releasing chamber 7 of the other, there are arranged a movable spring accepting member 22 contacted with a spring 24 and edge surface cam 26 contacted with the member 22 in way of cam follower portion 27 so as to control the diaphragm. A control lever 30 of a fuel injecting pump 28 is connected to the cam 26 in way of shaft 25 in order that the cam 26 can be rotated.
