Abstract

In a water outlet, the deterioration of sealing performance is prevented by a sealing member sealing between a pipe and the connecting port of the water outlet. A water outlet is provided at a coolant outlet of an internal combustion engine to which a pipe leading coolant out of the engine is connected, having a dish-shaped body fixed to the engine, a cylindrical connecting port provided to rise outward from the body portion and to be inserted into the inside of the pipe, and a sealing member on the outer circumference of the connecting port. A convex portion is provided on the outer circumferential side of the connecting port to rise outward from the body, and an annular sealing member is provided between the connecting port and the pipe, and at least a circumferential portion of the pipe is disposed between the convex portion and the connecting port.

First claim

The invention claimed is:

1 . A water outlet provided at a coolant outlet of an internal combustion engine and configured to allow a pipe to be connected thereto, the pipe leading a coolant to an outside of the internal combustion engine; the water outlet comprising:
a dish-shaped body fixed to the internal combustion engine; a tubular connecting port provided so as to rise outwards from the body and inserted into the pipe; and a protrusion provided on an outer peripheral side of the connecting port so as to rise outwards from the body, wherein an annular seal member is provided between the connecting port and the pipe, at least a part of the pipe of a circumferential direction is disposed between the protrusion and the connecting port, and the protrusion is formed in an arc shape in plan view when seen from an axial direction of the connecting port.

2 . The water outlet according to claim 1 , wherein
a gap is formed between the connecting port and the pipe along the circumferential direction, and the protrusion is disposed at a location so as to come into contact with the pipe before the connecting port and the pipe come into contact with each other when the connecting port and the pipe move relatively in a radial direction.

3 . The water outlet according to claim 1 , wherein the protrusion is formed to cover a half circumference portion of the connecting port along a concentric circle of the connecting port.

4 . The water outlet according to claim 1 , wherein
an annular gasket is provided between the body and the internal combustion engine so as to surround the coolant outlet of the internal combustion engine, and both ends of the protrusion in the circumferential direction are located on an outer circumferential side of the gasket.

5 . The water outlet according to claim 1 , wherein a tip of the protrusion in a height direction is located at the same height as the height of the sealing member.

6 . The water outlet according to claim 1 , wherein
a temperature sensor is mounted on the body, and a pair of walls located on both sides, with the temperature sensing unit of the temperature sensor therebetween, is closer to each other toward the bottom of the body.

7 . The water outlet according to claim 1 , wherein the pipe conducts the coolant to a thermostat attached to a water pump which sends the coolant to the internal combustion engine.

8 . The water outlet according to claim 1 , wherein the protrusion is located on an upper side or a lower side of the connecting port in a state of being mounted on a vehicle.
