調節装置。[Scope of Claim for Utility Model Registration] A circulation circuit for circulating cooling water of an internal combustion engine, a cooling device for cooling the cooling water provided in this circulation circuit, a rotation speed detector for detecting the rotation speed of the internal combustion engine, The temperature detector detects the temperature of the cooling water on the cooling water inlet side of the circulation circuit, and controls the cooling operation of the cooling device based on the rotational speed of the internal combustion engine and the temperature of the cooling water. The adjustment device includes a bypass pipe that communicates between the cooling water inlet side and the cooling water outlet side of the circulation circuit, a water pressure detector that detects the water pressure on the cooling water inlet side of the circulation circuit, and a water pressure detector installed in the circulation circuit. a compensation pump for compensating the amount of circulating water; a rotation speed high/low determination unit that determines whether the rotation speed of the internal combustion engine is high or low and selects and sets either a high rotation mode or a low rotation mode according to the determination result; This device opens and closes the bypass pipe, and controls the bypass opening/closing part that closes in high speed mode and opens in low speed mode, and the compensation pump, so that the detected water pressure is equal to the set pressure in high speed mode. 1. A temperature control device for internal combustion engine cooling water, comprising: a pump control section that controls the amount of water circulated in the cooling device so that the amount of water does not fall below a set amount of water in a low rotation mode.
