Abstract
To make it possible to extract air from a water pump without the need for a dedicated structure for air extraction in the water pump which supplies cooling water to a cooling jacket on a cylinder head or cylinder block of a horizontally opposed or V-type engine. A circular pump chamber for rotatably housing an impeller inside a pump housing of a water pump includes an upper discharge path extending diagonally upwards and connecting to an upper end section of the pump chamber, and a lower discharge path extending diagonally downwards and connecting to a lower end section of the pump chamber. First and second connecting pipes respectively extending in a straight line along a line extended from the upper and lower discharge paths have inner ends communicating with the upper and lower discharge paths, and outer ends forming first and second discharge ports.
