- This Short circuit is circulated only a part of the coolant without the cooler flow through to reduce the heating time.
- this Cooling circuit provided an expansion tank, which as a coolant storage and as Compensation reservoir for temperature-related fluctuations in the volume of the coolant serves.
- this expansion tank serves as an air or gas separator, for what Vent lines from high points of the internal combustion engine and / or of the cooler open into this expansion tank.
- the expansion tank is usually integrated into the circuit so that it is independent of the Operating temperature of the coolant and thus both in the main circuit and in Short circuit of its storage, compensation and ventilation function fulfilled. Consequently must also when the engine is cold started or during the warm-up phase the coolant volume in the expansion tank is also heated. Thereby the engine warms up, resulting in higher consumption and leads to higher pollution levels.
- the ventilation line is advantageously blocked in Dependence on the operating temperature of the coolant and / or on the pressure in the Reservoirs.
- the pressure in the expansion tank depends on the temperature-dependent change in volume of the coolant, so that indirectly a temperature-dependent blocking or opening of the ventilation line to Expansion tank is done.
- Such a pressure or temperature-dependent connection and disconnection of the Vent line is advantageously done by the check valve on Reservoir arranged and its valve member by a pressure in the Expansion piston loaded piston is adjusted. It can in particular advantageously the valve member itself as a pressurizable piston be trained.
- the opening point is set.
- the opening pressure or the Opening temperature is in the range of the opening temperature of the thermostatic valve. An opening temperature or an opening pressure that indicates an earlier opening of the Check valve compared to the thermostatic valve, but is also possible.
- Vent lines are provided in such a cooling circuit, the for example with the cooler of the cooling circuit (heat exchanger) and the housing the internal combustion engine are connected, they can advantageously on Check valve are merged. So that are both through the valve member Vent lines or all vent lines can be blocked, thereby reducing the construction effort is significantly reduced.
- the check valve regardless of the pressure in the Expansion tank can be operated manually, so that for an initial filling, Refilling or during maintenance and repair the filling of the cooling circuit and of the expansion tank can be done in a simple manner.
- the cooling circuit according to the invention is not restricted to this Embodiment in Fig. 1 schematically using the example of a two-row Internal combustion engine with cylinders 1 to 6 shown.
- the not shown Housing 7 of the internal combustion engine has cavities which are also in the region of the Cylinder block and cylinder head, not shown, are arranged. This are flowed through by the coolant during operation of the internal combustion engine.
- the Circulation of the coolant is carried out by a coolant pump 8, which is in this Embodiment on the suction side with a thermostatic valve 9 known per se connected is.
- This thermostatic valve 9 is a function of the Operating temperature of the coolant, the connection between the coolant pump 8 and Housing 7 of the internal combustion engine released to a cooler 10 (heat exchanger) or blocked.
- the coolant pump 8 rolls the coolant in one Short circuit in which the cavities in the housing 7 of the internal combustion engine and a heating heat exchanger 11 are flowed through without the Cooler 10 is flowed through.
- Exceeds that Operating temperature of the coolant is the predetermined opening temperature of the Thermostat valve 9, the connection of the coolant pump 8 to the radiator 10 opened so that all of the coolant is circulated through the radiator 10 (Main circuit).
- the suction side of the coolant pump 8 is one Expansion tank 12 connected as a storage and buffer tank for the Coolant is used.
- the expansion tank 12 is known per se Pressure relief valve 13 provided, depending on the internal pressure of the container Connection to the environment enabled. The above the coolant level 14 in Expansion tank 12 located gas can be exceeded when a predetermined maximum pressure can be relaxed.
- the Connection of the vent lines 15 and 16 to the expansion tank 12 is in each case lockable via a check valve 17.
- FIG. 2 shows the housing 18 of the expansion tank 12, which is only partially shown, the top of which has an opening 19 into which the valve housing 20 of the Check valve 17 is used.
- the cylindrical valve housing 20 of the check valve 17 is inserted with its open underside 21 into the opening 19 of the housing 18 and sealed by a sealing ring 22.
- Above the Expansion tank 12 open into the interior of the valve housing 20 two Vent connections 23, 24, of which the vent connection 23 with the Vent line 15 and the vent connection 24 with the vent line 16 connected is.
- a piston-shaped valve member 25 Inside the cylindrical valve housing 20 is a piston-shaped valve member 25 axially movable, the end face 26 of the pressure p inside the Expansion tank 12 is acted upon. On the opposite inside of the Valve member 25 is supported on one end of a compression spring 27, the other End rests on an end face 28 of the valve housing 20.
- the valve member 25 has furthermore on the side facing away from the expansion tank 12 a pin 29, which is embraced by the compression spring 27 and the end face 28 of the valve housing 20th penetrates. Outside the valve housing 20, this pin 29 is one Disc 30 includes, in the end position shown in FIG. 2, the valve member 25th abuts as an end stop on the outside of the valve housing 20. In the in Fig.
- the valve member 25 is in its lower end position or the closed position. In this switch position are the two vent connections 23 and 24 through the valve member 25 on one side closed, i.e. there is no connection of the ventilation lines 15 and 16 to the expansion tank 12. If the internal pressure in the expansion tank 12 exceeds due to the temperature-dependent increase in volume of the coolant Biasing the compression spring 27 predetermined opening pressure, the valve member 25th raised against the action of the compression spring 27, so that the connection of the Vent connections 23 and 24 and thus the vent lines 15 and 16 for Expansion tank 12 is released.
- the coolant level / coolant volume is in the Expansion tank low and the tank pressure corresponds to that Ambient pressure. If the volume of the coolant increases as a result of the heating, it increases the coolant level in the expansion tank and thus its internal pressure. exceeds the internal pressure a predetermined maximum pressure, the pressure relief valve opens Environment, and the gas in the expansion tank can escape, so that the pressure drops. The pressure difference between the tank pressure and Ambient pressure acts on the valve member or the piston, which on the other hand through the Effect of the spring is applied. If a predetermined is exceeded Opening pressure, the valve member is displaced and the vent connections be released.
- the compression spring is designed so that its preload is straight sufficient to cool the coolant, the valve member against the friction of the To move the seal back to its original position.
- a higher design by appropriate design of the spring element Opening force and thus a higher opening temperature / a higher To specify the opening pressure.
- the valve housing lower part 37 consists of an outer ring 39, the outer Ridge 31 of the housing 18A engages over and is screwed to it. With this ring 39 is connected to an inner ring 40, which is the inner annular web 32 overlaps and includes.
- the ring 40 has two through openings 41, 42 connected to the channels 35 and 36 of the housing 18A. Between Both rings 39 and 40, the valve housing lower part 37 has a plurality of passages 43 on that with the annular space 44 between the inner and outer web 31, 32 of Housing 18A are connected. Again, the connection is through an individual Passage also possible.
- the cup-shaped piston 46 lies with its bottom 48 on the inside 49 of the Roll membrane 45 and has a circumferential circumferential annular groove 50 into which a encircling ring 51 of the rolling membrane 45 engages.
- the piston still has one Pin 52, which is guided in the valve housing upper part 38 and penetrates this.
- the Pin 52 is surrounded by a compression spring 53, which is on the one hand at the bottom 48 of the Pistons 46 and on the other hand supported on the valve housing upper part 38.
- the internal pressure of the expansion tank does not act in this embodiment the piston but via the openings 33, the annular space 44 and the passages 43 on the outer area of the rolling membrane 45, while the inner area of the Roll membrane the vent closures 41.42; 35, 36 closes or opens.
- bracket element 54 On the pin 52 is a pivotable outside of the valve housing upper part 38 Fixed bracket element 54 with which the piston 46 and thus the rolling membrane 45th can be raised manually regardless of the pressure in the expansion tank 12.
