<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive exhaust gas recirculating device of an internal combustion engine capable of opening an exhaust valve in a microscopic opening in the initial stage of an intake stroke or a compression stroke with a simple structure. <P>SOLUTION: In this exhaust gas recirculating device of the internal combustion engine, a valve system camshaft 36 is provided with a first guide hole 55 in its axial direction of a food storage and cooking paper vessel and a second guide hole 63 in the radial direction for communicating this first guide hole 55 with a base surface of an exhaust cam 36e formed on the camshaft 36. The first guide hole 55 is fitted with a plunger 56 operated to an advance position from a retreat position by an actuator 53, and the second guide hole 63 is also fitted with a lift pin 64 moving to an operation position for projecting the outer end outward to the base surface from a nonoperating position for retreating the outer end inward to the base surface of the exhaust cam 36e by interlocking with the movement to between the advance positions from the retreat position of the plunger 56. The exhaust valve 29e is opened in the microscopic opening in the initial stage of the intake stroke or the compression stroke by the movement to the operation position of this lift pin 64. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
