Claims

[Claims for Utility Model Registration] (1) A first rotating shaft to which rotational force from the engine is always transmitted, a first impeller fixed to the first rotating shaft, and a first impeller that can cut off the rotational force from the engine. A two-rotation shaft, a second impeller fixed to the second rotation shaft, each pump chamber formed in the casing and accommodating the first impeller and the second impeller, and each of the pump chambers in parallel. a plurality of passages, a rotating means that is rotatable with respect to the second rotating shaft and constantly rotates while connected to the first rotating shaft, and a rotating means for transmitting the rotation of the rotating means to the second rotating shaft. A variable water pump comprising a clutch and a control means for connecting or disengaging the clutch, and connecting the clutch to rotate a second impeller when the engine is rotating at low speed. (2) A first rotating shaft to which the rotational force from the engine is always transmitted, a first impeller fixed to the first rotating shaft, a second rotating shaft to which the rotational force from the engine can be cut off, and the second a second impeller fixed to a rotating shaft; pump chambers formed in a casing and accommodating the first impeller and the second impeller, and one passage in series passing through the plurality of pump chambers; a rotating means that is rotatable with respect to the second rotating shaft and constantly rotates in connection with the first rotating shaft; a clutch for transmitting the rotation of the rotating means to the second rotating shaft; 1. A variable water pump comprising control means for connecting or uncoupling a clutch, and for connecting a clutch to rotate a second impeller when the engine is rotating at low speed.
