る可変容量ウォータポンプ。In a water pump equipped with a pump impeller fixed to a rotating shaft for forcibly supplying cooling water, and a mechanical seal disposed behind the pump impeller, the rotating shaft is configured to face a cooling water flow path. A temperature sensing means is mounted on the shaft, a thrust shaft driven by the temperature sensing means and movable in the axial direction is disposed coaxially with the rotating shaft, and a disk is mounted so as to be movable in the axial direction integrally with the thrust shaft. A variable displacement water pump characterized in that the pump impeller is fixed, and a shroud is provided around the entire outer circumference of the disk, and the impeller operating range of the pump impeller is changed by axial movement of the disk.
