Abstract

PURPOSE:To prevent ocurrence of negative pressure at the suction side by putting the reserver tank in communication with the cooling water flow-in part of a water pump through a cooling water supplying passage, which is equipped with a check valve designed to allow the cooling water to flow only in the direction from the reserve tank to water pump. CONSTITUTION:A reserver tank 22 in communication with the radiator cap 21 of a radiator 3 is put in communication with the suction side of a water pump 2 through a cooling water supplying passage 26. This cooling water supplying passage 26 is equipped with a check valve 27, which allow the cooling water to flow only in the direction from the reserver tank 22 to the suction side of water pump 2. Accordingly, the check valve 27 is opened when the negative pressure in the suction passage 25 for the water pump 2 exceeds a certain set value, and then the check valve 27 is opened and the cooling water is supplied from the reserver tank 22 to the passage 25. Thus negative pressure at the suction side is prevented.
