Description

そして、前記バイパス通路は、前記サーモスタットハウジングの底面部にボトムバイパス孔を通じて連通しており、前記サクション通路用の流出ポートは、前記サーモスタットハウジングの周側面部に開口することで当該サーモスタットハウジングに連通しており、前記冷却液アウトレット部材は、前記ボトムバイパス孔をバイパスして前記冷却液ジャケットの出口と前記サーモスタットハウジングとを連通させる、前記ラジエータ通路用の流出ポートよりも小径の感温用バイパス通路をさらに備え、前記感温用バイパス通路は、前記サーモスタットハウジングの周側面部における前記サクション通路用の流出ポートの連通位置とは逆側位置に開口していて、前記サーモスタット弁の感温部に向かって冷却液を流すようにドリルによる孔開け加工によって形成されている。 The bypass passage communicates with a bottom surface portion of the thermostat housing through a bottom bypass hole, and the outflow port for the suction passage communicates with the thermostat housing by opening to a peripheral side surface portion of the thermostat housing. The coolant outlet member has a temperature-sensitive bypass passage having a smaller diameter than the outlet port for the radiator passage, which bypasses the bottom bypass hole and communicates the outlet of the coolant jacket and the thermostat housing. The temperature sensing bypass passage further opens to a position opposite to the communication position of the outflow port for the suction passage in the peripheral side surface portion of the thermostat housing, toward the temperature sensing portion of the thermostat valve. drilling with a drill to flow cooling fluid It is formed by the factory.

Claims

It is attached to the engine and communicates with an outlet of a coolant jacket provided in the engine, and an outlet port and an inlet port for a radiator passage in which a radiator is provided in the middle of the coolant circulation pump. An outlet port for the communicating suction passage, and a coolant outlet member having at least a bypass passage for bypassing the radiator passage;
The coolant outlet member is housed in a thermostat housing interposed between the inflow port for the radiator passage, the outflow port for the suction passage, and the bypass passage, and the coolant in the thermostat housing. A thermostat valve that senses the temperature of the radiator passage and selectively connects one of the radiator passage and the bypass passage to the suction passage,
The bypass passage communicates with a bottom surface portion of the thermostat housing through a bottom bypass hole.
The outflow port for the suction passage communicates with the thermostat housing by opening in a peripheral side surface portion of the thermostat housing,
The coolant outlet member further includes a temperature-sensitive bypass passage having a smaller diameter than the outflow port for the radiator passage, bypassing the bottom bypass hole, and communicating the outlet of the coolant jacket and the thermostat housing,
The temperature-sensitive bypass passage is opened at a position opposite to the communicating position of the outflow port for the suction passage in the peripheral side surface portion of the thermostat housing, and the coolant is directed toward the temperature-sensitive portion of the thermostat valve. Engine coolant passage structure formed by drilling with a drill to flow.
