摘要:
A flow channel switching device provided in an oil circuit to switch the oil flow channel in accordance with the temperature of the oil. The flow channel switching device includes: a thermo-valve case that includes a plurality of flow passages that are communicated outside of the case; and a cylinder that is formed to move in the thermo-valve case and switches the oil flow channel in accordance with the temperature of the oil. The cylinder moves to a predetermined position and is fixed by means of an external member when the fluid at a low temperature is fed into the fluid circuit.

Les conduites d'entrée et de sortie (9, 10) du réservoir isolé (1) sont reliées au volume d'air (5) du vase d'expansion (2) du circuit de fluide de façon à se remplir d'air lorsque le moteur est arrêté, cet air séparant physiquement le liquide contenu dans le réservoir de celui contenu dans le reste du circuit. Les pertes de chaleur sont ainsi encore diminuées. Application au circuit de refroidissement du moteur d'entraînement d'un véhicule.

A cooler apparatus includes: a coolant passageway; a water pump that circulates coolant in the coolant passageway; a thermostat that includes a heater that heats a temperature sensitive portion; and a controller. The controller is configured to drive the water pump and cause electric current to flow through the heater at a first energization amount when an operation in which the coolant is injected into the coolant passageway is started. The controller is also configured to stop electric current to flow through the heater if the water pump races when the electric current flows through the heater at the first energization amount.

A coolant tank for receiving a fluid from the cooling system of an internal combustion engine includes a pressurized tank having a pressurized reservoir configured to contain the fluid and an overflow tank integrated with the pressurized tank. The pressurized reservoir includes an inlet port configured to receive the fluid from the cooling system, an outlet port configured to direct the fluid from the pressurized reservoir to the cooling system, a fill neck in fluid communication with the pressurized reservoir, and a pressure cap removably coupled to the fill neck. The overflow tank includes an overflow reservoir maintained at atmospheric pressure and configured to receive overflow fluid from the pressurized reservoir when the liquid of the cooling system expands. At least a portion of the fill neck is positioned within the overflow reservoir.

Le raccord comporte un premier et un second conduits (26, 27) placés sensiblement dans le prolongement axial l'un de l'autre, une chambre (28) ayant une paroi cylindrique (35) ouverte à ses extrémités auxquelles sont raccordés les conduits (26, 27) et un troisième et un quatrième conduits (29, 30) en dérivation débouchant latéralement dans la chambre (28). Le troisième et le quatrième conduits (29, 30) sont raccordés à la chambre (28) par des ajutages (36, 37) dont les axes sont situés dans un plan transversal perpendiculaire à l'axe de la chambre (28). Les ajutages (36, .37) sont disposés au moins partiellement en retrait vers l'intérieur de la chambre (28) pour diminuer l'encombrement transversal du raccord. Une paroi inclinée (31) traversée par un orifice calibré (31a) sépare la chambre (28) en deux parties dans chacune desquelles débouche un conduit en dérivation (29, 30).
摘要:
A vapor cooled type internal combustion engine is provided with an auxiliary reservoir and a coolant management system. The management system establishes fluid communication between the reservoir and a cooling circuit of the engine in a manner to fill the latter with liquid coolant when the engine is not in use and thus exclude contaminating non-condensible air from same, and monitors the operation of the system when operating in a closed mode to determine if too much or too little coolant has been retained in the circuit following a warm-up mode wherein the excess coolant which fills the system when cold, is displaced by its own vapor pressure. The management system also ensures that the cooling circuit is not switched from closed to open states while the possibility of superatmospheric pressures developing therein exist and thus prevents violent displacement of coolant out of the circuit to the reservoir in a manner which invites spillage of coolant and the entry of large amounts of contaminating air.
