Abstract: A cooling device for an internal combustion engine includes a jacket provided in the engine such that a coolant is capable of flowing through the jacket, a flow control valve connected to at least one of an inlet side of the jacket and an outlet side of the jacket to adjust a flow rate of the coolant. The flow control valve includes a housing having a flow passage communicating with the jacket such that the coolant is capable of flowing through the flow passage, a valve body arranged in the housing to open or close the flow passage, and a heat transfer member contacting the engine and a part of the housing accommodating the valve body to transfer a heat from the engine to the housing.

Abstract: A valve device includes: a ball valve having a ball face shaped in a convex spherical surface; and a valve seat having a seat face shaped in a concave spherical surface. The seat face is pressed onto the ball face. The ball valve is rotated to open a valve by communicating a valve opening defined in the ball valve and a seat opening defined in the valve seat with each other, and to close the valve by stop the communication. A diameter of the seat opening ϕ2 is smaller than a diameter of the valve opening ϕ1. A curvature radius of the ball face R1 is smaller than or equal to a curvature radius of the seat face is R2.

Abstract: In an oil cooling system for a supercharged engine, coolant is introduced from a third coolant supply passage that branches from a first coolant supply passage into a coolant circulation passage of an oil cooler. The coolant has not cooled an engine and a turbocharger. By efficiently cooling lubricating oil (lubricating oil after lubricating supercharger) having lubricated the respective cooled portions of the turbocharger, oil-deterioration-suppressing effect can be improved even with the coolant of a small amount.
