Claims

[Scope of utility model registration request]

Exhaust gas passage for recirculating exhaust gas from the exhaust pipe of the engine to the intake pipe, a control valve installed in the middle of this passage to adjust the degree of opening of the passage, and exhaust pressure for extracting exhaust gas as exhaust gas pressure. An exhaust gas recirculation control valve characterized by comprising an intake port and an exhaust pressure outlet pipe that cools the exhaust gas from the exhaust pressure intake port and discharges it to the outside.
