Description

Technical field

The present invention relates to a degassing system, which makes it possible to release gas accumulating, in particular, in cooling systems of an internal combustion engine.

State of the art

As the duration of the operation of internal combustion engines increases, their temperature rises. Cooling systems are designed to maintain the most suitable engine operating temperature. These cooling systems, as a rule, carry the heat that they receive from the engine to the radiator through the coolant. Thus, the excess heat present in the engine is transferred to the environment. However, the engine at its initial start-up is cold. In order to achieve the most suitable operating temperature, the engine must run for a while. If the said cooling system is operating while the engine is warming up from the initial start up to the most suitable operating temperature, the time that the engine needs to reach this most suitable operating temperature will increase. This, in turn, will cause engine wear, its inability to efficiently burn fuel and, thus, increase both fuel consumption and the amount of unburned fuel discharged through the exhaust pipe. For this reason, thermostats are used to ensure that the cooling system will not work until the engine reaches the most suitable temperature. If the coolant temperature is lower than the predetermined temperature, the thermostat prevents the coolant from passing to the radiator. When the coolant temperature rises, the thermostat opens and thus allows the coolant to pass to the radiator. In said cooling system, air may accumulate from time to time. In this case, the efficiency of the cooling system is reduced.

In particular, in engines of heavy freight vehicles containing two bag-type thermostats, these thermostats are located below the highest level of coolant, and thus it is not possible to exhaust gases accumulating in the cooling system. Degassing in dish-type thermostats is usually carried out through an exhaust valve located on the thermostat in the bypass position. For this reason, degassing is carried out more easily in comparison with sleeve thermostats.

International Patent Document WO No. 9713059, which is a patent application in the art, discloses a poppet type thermostatic valve that is installed in the cooling circuit of an internal combustion engine and which controls the flow.

U.S. Patent Document No. 6045051, which is a patent application known in the art, describes an improved prior art thermostat cover having a specific shape.

U.S. Patent No. 4,300,718, which is a patent application known in the art, describes a housing comprising a plate-type thermostat and a degassing passage located at the outlet of an engine cooling system.

SUMMARY OF THE INVENTION

The aim of the present invention is to provide a degassing system that allows the release of gas accumulating, in particular, in cooling systems of an internal combustion engine.

Another objective of the present invention is to provide a degassing system that allows the release of gas accumulating, in particular, in cooling systems of an internal combustion engine with any position of the thermostat.

DETAILED DESCRIPTION OF THE INVENTION

A degassing system designed to solve the problem of the present invention is illustrated in the accompanying drawings, in which:

figure 1 is a schematic view of a degassing system,

Figure 2 is another view of a degassing system.

The components in the drawings are given the following reference position:

1 - degassing system

2 - case

3 - ledge

4 - protrusion hole

5 - feed channel

6 - storage camera

7 - accumulation channel

8 - exhaust channel

The degassing system (1) of the present invention mainly comprises:

- at least one housing (2), which is made in the form of a cover, the sides of which are higher than its middle part,

- at least two protrusions (3), each of which can cover at least one part of the thermostat and which preferably protrude upward from the middle part of the housing (2) in the same direction as the sides of the housing (2),

- at least two holes (4) of the protrusions, each one of which is made in each protrusion (3) and which allow gases accumulating around the protrusion (3) to be emitted from the region of this protrusion (3),

- at least two feed channels (5), each of which is provided for each protrusion hole (4), and which can conduct gases entering the protrusion hole (4),

- at least one storage chamber (6), in which the gases transported by the supply channels (5) accumulate,

- at least one accumulation channel (7), which is located in the accumulation chamber (6) and which allows you to emit gases from this case (2), which may have accumulated in the case (2), and while these gases enter the storage camera (6),

- at least one exhaust channel (8), which allows to let out air accumulating in the storage chamber (6).

The degassing system (1) of the present invention contains basically at least one body (2), which is made in the form of a cover, the sides of which are higher than its middle part. As an example of the shape of the case (2), a tray can be given which is flat in the middle and has sides that bend upward. On the flat part of the housing (2) there are at least two protrusions (3), each of which can cover at least one part of the thermostat. The said protrusions (3) are preferably circular in accordance with the upper part of the thermostat, which will be located in them. Said circular shape, rising from the middle part of the housing (2), in the same direction as the sides of the housing (2), forms a cylinder. There are at least two openings (4) of the protrusions, each of which is made in each of the said protrusions (3) in order to allow gases accumulating in the protrusion (3) to be emitted from the protrusion (3). Said protrusion openings (4) are connected to at least two supply channels (5), each of which is intended for each protrusion opening (4) and which can conduct gases entering the protrusion openings (4). The degassing system (1) of the present invention comprises at least one storage chamber (6) in which gases transported by the supply channels (5) accumulate. In addition, the degassing system (1) of the present invention contains at least one storage channel (7), which is located in the storage chamber (6) and which allows to emit gases from this housing (2) that may have accumulated in the housing ( 2), and the gases mentioned enter the storage chamber (6). The accumulation chamber (6) contains at least one outlet channel (8), which allows the air accumulating in this accumulation chamber to be let out. Mentioned exhaust channel (8) allows gases that accumulate in the cooling system to which the degassing system (1) of the present invention is connected and which are collected by this degassing system (1) to be emitted from said cooling system.

In a preferred embodiment, the thermostat bodies installed in the degassing system (1) of the present invention are located at higher points than the cooler in the cooling system to which the degassing system (1) is connected.

In a preferred embodiment of the invention, the openings (4) of the protrusions make it possible to carry out degassing with the half-open, fully open and bypass position of the thermostats that are connected to the degassing system (1) of the present invention. In this embodiment, the accumulation channel (7) allows degassing in the half-open and in the bypass positions of said thermostats. Thus, degassing may be possible for each position of said thermostats.

In a preferred embodiment of the present invention, the openings (4) of the protrusion with the supply channels (5) are cylindrical having a diameter of 4 mm. In this embodiment, the outlet channel (8) is circular having a diameter of 1.5 mm. These values are given for the present invention; however, for other embodiments, these values may be different.
