Abstract
An injection valve is provided in a cooling device. An outer jacket is provided at an outside of the injection valve. A cylindrical partitioning unit divides an annular space into an outside passage on a side of the outer jacket and an inside passage on a side of the injection valve. A second pipe portion supplies cooling water into the annular space and a first pipe portion discharges the cooling water from the annular space. A first restricting portion is provided between the first pipe portion and the second pipe portion and it restricts a flow of the cooling water in the outside passage from a part on a side of the second pipe portion to a part on a side of the first pipe portion. A second restricting portion is provided at a position on a side of the first pipe portion opposite to an injection port. The second restricting portion restricts the flow of the cooling water between the outside and the inside passages. A communication passage is formed in the cylindrical partitioning unit at a position above the first restricting portion and it communicates the outside and the inside passages to each other.
