Definitions

the invention relates to an expansion tank for the cooling liquid of a liquid-cooled machine, in particular an internal combustion engine of a vehicle according to the preamble of claim 1.
FIG. 1 shows such a known expansion tank 10 in a highly schematic view.
the surge tank 10 is usually mounted so that it represents the highest point in the cooling system.
the expansion tank 10 has an inlet connection arranged in the lower region of the expansion tank 10 and an outlet connection for connecting the expansion tank 10 to the cooling circuit of the internal combustion engine (not shown in each case).
the expansion tank 10 further has a filling nozzle 4 arranged in the upper region of the expansion tank, which has a lower edge 9 spaced from the expansion tank ceiling 14 for limiting the filling level.
a filling nozzle 4 sealing valve 5 which serves to secure the cooling system against overpressure and over which the expansion tank 10 can be filled with the coolant 1.
the maximum filling of the expansion tank 10 usually corresponds to a filling with a cold engine with coolant 1 to the lower edge 9 of the filling nozzle 4, as in FIG. 1 shown.
Conventional expansion tank 10 have at maximum filling with coolant 1 a fixed air volume 2. If internal combustion engines with different cooling circuits to be equipped with the same expansion tank 10, this has the following disadvantages: In cooling circuits with low heat input is not a sufficient form. In cooling circuits with high heat input, however, the form pressure is deactivated via the valve 5, or it is ejected coolant. These disadvantages can be avoided by providing different surge tanks, which are each adapted to the specific cooling circuits in which they are used. However, this increases the number of variants and thus the development and component costs.
the object of the invention is in particular to provide a surge tank, which is better adapted to the requirements of different cooling circuits.
the invention is also based on the object of a cost-saving design of such a reservoir.
the compensating container according to the invention for the cooling liquid of a liquid-cooled machine has in accordance with the prior art at least one inflow connection arranged in the lower region of the compensating container and an outflow connection for connecting the compensating container to a cooling circuit of the internal combustion engine.
the surge tank further comprises a arranged in the upper region of the expansion tank filler neck, which has a spaced from a surge tank ceiling bottom to limit the level and at least one filling nozzle sealing valve for filling the surge tank and to secure the cooling system against overpressure.
the liquid-cooled machine can in particular be a liquid-cooled internal combustion engine of a vehicle.
One highlighted application concerns a marine vessel or commercial vehicle
the stated objects are achieved in that a remaining at a maximum filling of the expansion tank with coolant remaining air volume in the expansion tank, d. H. is variably determinable.
expansion tank can be adapted to different requirements of different cooling circuits only by changing the available volume for the air in the expansion tank.
a low air volume can be set to build up a sufficiently high pre-pressure.
a high volume of air can be adjusted so that too high a pre-pressure builds up or so that no coolant is ejected.
the expansion tank with variable air volume can thus be used as a uniform same component in cooling circuits, which differ due to their nature, in particular their coolant heat input.
a particular advantage of the invention is thus the increased flexibility in the admission pressure setting in the cooling circuits and the cost savings through standardization or variant reduction, since a component can be adapted for use in different cooling circuits or cooling systems.
At least one air chamber hereinafter also referred to as an air pocket, can be provided for adjusting the remaining volume of air in the expansion tank, comprising an air inlet opening lying in the interior of the expansion tank above the lower edge of the filling nozzle, which are opened and closed with an associated closure device can.
the arrangement of the outlet opening above the lower limit of the filling nozzle always ensures the same maximum filling when filling the expansion tank with coolant.
one or more air pockets can be provided, which can be brought respectively with the associated closure device (closure member) in fluid communication with the base gas volume of the surge tank to increase the gas volume in the expansion tank.
closure device closure member
the air pocket is closed, so that the available gas volume is not increased.
the at least one air chamber can be arranged on the inside in the upper region of the expansion tank.
the at least one air chamber may also be arranged outside of the expansion tank and be connected via a hose or pipe to the upper region of the expansion tank.
the expansion tank can have at least two air chambers.
the number and volume of the air chambers may be determined depending on the desired air volume graduation.
One possibility of erfindungsmä touch realization provides that the internal volume of the air chambers is designed to vary in size. However, the internal volume of the air chambers can also be made the same size.
the closure device associated with an air chamber can be designed as a closure screw, a closure cover or a flap. This allows a cost effective design variant to manually adjust the available volume for the air in the expansion tank.
the closure device can be designed as a check valve, as a spring-loaded valve or as a pneumatically or electrically actuated valve. This offers the advantage that the opening and closing of the air chambers can be pressure-dependent and / or automated, in particular during operation of the cooling circuit.
the air inlet opening of the at least one air chamber so that no coolant can enter the at least one air chamber during operation of the expansion tank when it is open.
a separate channel guide and / or a spray cover is provided for this purpose.
Another aspect of the invention relates to a utility vehicle or vessel having a surge tank as disclosed herein.
compensation container 20 and 30 is located in the additionally provided two air pockets 6, each having an associated closure member 7, with which each air pocket 6 can be selectively opened or closed.
an air pocket 6 is in fluid communication with the base gas volume of the surge tank 20 and 30.
Each of the air pockets 6 has an air inlet opening 8, which lies above the lower edge 9 of the filling nozzle 4 in the upper inner region of the surge tank and closed with the closure member 7 can.
the closure member 7 is designed as a screw plug.
the expansion tank 30 further includes, as already stated above, arranged in the upper region of the expansion tank 30 filling nozzle 4, which has a spaced from the surge tank ceiling 14 lower edge 9 for limiting the level, and a filling nozzle 4 sealing Valve 5, which serves to secure the cooling system against overpressure and over which the expansion tank 30 can be filled with the coolant 1. Below the valve 5, an overflow pipe 16 is arranged, through which coolant can flow when the valve 5 is opened. In the expansion tank 30, a connection 15 for a level sensor for level measurement and a port 17 for the form pressure measurement are also provided.
a baffle element is provided to improve the air bubble separation, which is preferably designed as a partition wall 13.
a partition has the function to change the flow direction of the liquid and to increase the flow path of the coolant in the expansion tank in order to separate as much air.
the two air chambers 6 are provided below the surge tank cover 14 in the upper region of the surge tank 30 on the opposite side of the valve 4, the air inlet opening 8 can be closed or opened with a screw plug 7.
the screw head protrudes from the top of the surge tank 30 and can be operated from the outside.
the air chambers 6 can be opened to vary the volume of the air in the expansion tank available in the interior of the expansion tank and optimally adapted to the present cooling circuit.
the required air volume is first determined as a function of the coolant expansion, the required admission pressure and the opening pressure of the valve 5.
the required air volume is adjusted in the expansion tank by the base volume, d. h., All air pockets 6 are closed, or possibly by the base volume and the determined number of required air pockets 6, if an increased volume of air was determined.
the required number of air pockets 6 is then possibly opened by means of the screw plug 7, that is connected fluidly to the base volume.
the cooling circuit is then filled for the first filling with coolant to the lower edge 9 of the filling nozzle 4.
the engine is subsequently operated until the cooling circuit has been completely vented in order to remove any remaining air bubbles from the cooling circuit.
coolant is refilled with a cold engine, again up to the lower edge 9 of the filling nozzle 4.
