    [7] There are a number of reasons why one wants to vent the refrigerant, for example, poordeaeration of coolant results in cavitation of an engine water pump, rusty engine lining,engine overheating, cab HVAC system failure, EGR radiator erosion and other disadvantages. ToFor example, modern truck engines have relatively high fluid fate rates to oneleveling vessels, such as over four U.S. gallons per minute. As a result, it will bemore difficult to vent the refrigerant. In addition, high fluid flow rates can enter into oneequalization vessels result in the rupture of air bubbles into microbubbles (eg pin-sizedbubbles) which are more difficult to remove from the refrigerant.
    [8] It is known to make plastic leveling vessels of plastic for weight and cost saving reasons.
    [9] There is a need for an improved leveling vessel which is configured toreduce or minimize lu fi bubbles from recirculation through the engine cooling system.

    [24] FIG. 6 is an enlarged, cross-sectional view of the second embodiment of a leveling vessel;when the incoming fl fate of the refrigerant is attenuated by fl ertal objects.
    [25] The leveling vessel 10 according to the invention provides improved damping of an incomingflow of a coolant 12. Referring to FIG. 3, comprises an embodiment ofa reservoir in which the reservoir 14 defines a coolant inlet 16 adaptedfor connection to a motor. The coolant inlet 16 receives a fl fate of coolant 12 fromthe motor (shown as 112 in FIG. 1). Furthermore, the reservoir 14 comprises a reservoir outlet 19by which fl the fate of coolant 12 is returned to the engine.
    [26] The leveling vessel 10 further comprises a number of objects 18 arranged insidethe refrigerant reservoir 14. Most objects 18 are functionally adapted to surface at oneupper surface 20 of the coolant 22 in the reservoir 14 and to dampen the kinetic energy in the coolant whichfl fatalities from the engine. The plurality of objects 18 may cover a portion (not shown) of the entire upper surface 20 ofthe coolant 22 arranged inside the reservoir 14 or tal ert objects can cover the entire upper surface20 of the coolant 22 disposed within the reservoir 14, as shown in FIG. 3.
    [27] The plurality of objects 18 may be in a variety of forms such as, but not limited toto spheres, octagons, squares, rectangles, pyramids, or the like. Said fl ertalet object18 are made of polymeric material. The majority of objects 18 (which can be spheres, octagons,squares) can be hollow or solid. It should be understood that it can be more cost effectiveand lighter weight when the objects 18 are hollow instead of solid.
    [28] Referring now to FIG. 4A, a cross-sectional view of the first embodiment ofthe present description where the number of objects 18 forms your layers 24, 26, 28 near the surface 20 ofthe coolant 22 arranged inside the reservoir 14. It is understood that a first layer 24of the number of objects 18 can be arranged below the surface 20 of the coolant 22. A second layer 26 canbe provided at the surface 20 of the coolant 22 and a third layer 28 of the objects 18 may bearranged above the surface 20 of the coolant 22 shown.
    [29] Each of the objects 18 may be solid or perforated or both solid andperforated. Referring to FIG. 4B and 4C, the perforations 30 in the objects 18 increasethe surface area of the liquid 32 which would be exposed to air. The exposure of the surface area of the liquidfor the luñen causes a stress-relieving effect on the water. It is also implied that fl fateof the refrigerant 12 can pass through the perforations as shown in FIG. 4D.
    [30] Referring now to FIG. 5A-5C, another embodiment of one is shownleveling vessel 10 of the present disclosure. The leveling vessel 10 comprises a reservoir14, wherein the reservoir 14 defines a coolant inlet 16 which is connected to a motor (notshown). The coolant inlet 16 receives a fate of the coolant 12 from the engine. The leveling vessel10 further comprises a reservoir outlet 19 through which the flow of refrigerant 12 is returned tothe engine. The leveling vessel 10 further comprises a baffle (or grid) 32 and a number of objects18. The baffle (or grid) may 32 be attached to the inner surface of the reservoir 14 or be oneintegral part with the reservoir 14. The baffle (or grid) 32 forces the objekt ertal object 18 toremain in the upper part 34 of the leveling vessel 10 even when the leveling vessel 10 is inclined orstirred, as shown in FIG. 5B and SC. Therefore, because fluid flows fromrefrigerant inlet 16, there will always be a number of objects 18 to attenuate the fateof the refrigerant 12 before or when it comes into contact with the refrigerant 22 arranged insidein the reservoir 14.
    [31] FIG. SB shows the second embodiment of the present description in an inclined directionlocation. As shown, the surface 20 of the refrigerant remains horizontal. Most of the object 18 remains in itupper portion 34 of reservoir 14 due to baffle (or grid) 32. FIG. SC shows itthe second embodiment of the present description, in which the reservoir is stirred. Againthe för ertal object 18 will remain in the upper part 34 of the reservoir 14 due to the baffle(or the grid) 32 despite the movement of the reservoir 14 and the fate of the refrigerant 12 always comesattenuated under this condition.
    [32] As indicated, the number of objects 18 are arranged inside the coolant reservoir 14 in an upperpart 34 of the leveling vessel 10 and are functionally adapted to surface on an upper surface 20 ofthe refrigerant 22 in the reservoir 14. Most objects 18 interact with the baffle 32 functionallyadapted to attenuate the kinetic energy in the fl fate of coolant 12 from the engine. Consequently,air in the form of air bubbles minimized inside the refrigerant due to the attenuatedthe kinetic energy in the flow of coolant 12 from the engine and the dispersion of the lu bubblesfi nns in the refrigerant.
    [33] Like the first embodiment, it is understood that the number of objects 18 maybe either hollow or solid or semi-solid (perforated), as described above.
    [34] Each object 18 may have a diameter of about 1.27 cm (0.5 inches). However, it isimplied that the diameter may vary depending on the configuration of the leveling vessel 10.
    [35] Referring now to FIG. 6, air bubbles are dispersed due to objekt ertalet objects.
    The incoming fl fate of the refrigerant 12 entering the reservoir 14 therefore needsis only attenuated by coming into contact with fl number of objects 18. As shown isthe air bubbles 36 are dispersed and fl surface up to the surface of the refrigerant when the air bubblescomes in contact with fl ertal object 18. A thin fl surface film (38 in FIG. 6) is created over andaround the objects 18 which provides a shorter travel path for the air bubbles 36 to rise toexposed to lu fl and broken up.
