Abstract
PURPOSE: To offer simple construction and smooth operation by integrating an actuator with a control-valve-running load motor, which feeds back the value of current pressure in an EGR system.
CONSTITUTION: An EGR system is constituted that a flow control valve 18 whose opening is controlled by a negative pressure motor 35 is equipped in an exhaust gas feedback course 7 communicating an exhaust gas passage with a suction passage 1. An actuator 37, consisting of a pressure applied chamber 41 and reference pressure chamber 40 in communication with a space at a reference pressure near atmospheric pressure, is mounted on said negative pressure motor 35, having a working rod 38 which moves according to pressure difference between those chambers. Suction negative pressure is sent through a negative pressure passage 46 to the negative pressure chamber 45 of said negative pressure motor 35. Venturi pressure in Venturi chamber 14 located in a feedback course 13 is sent through a pressure applied passage 42 to the pressure applied equipment 41 in the actuator 37.
