United States Patent O 3,195,294 FLUD SEPARATR Anthony Verdura, Detroit, and Theodore Z. White, Dearborn Township, Mich., assignors to Ford Motor Company, Dearborn, Mich., a corporation of Belaware Filed Mar. 20, 1961, Ser. No. 96,962 10 Claims. (Cl. 55--159) This invention is concerned with means for separating or purging gas or air bubbles from a ilowing liquid. More particularly it is concerned with a separating device for removing gas bubbles from an automotive cooling system.
Cooling systems having entrained gas bubbles are ineiiicient. Water pump cavitation, increase in rust formation and corrosion, overheating, foaming of the coolant and overflow loss of the coolant are a few of the most common problems encountered as a result of air contamination.
Present cooling systems generally embody a reservoir and surge tank either as a part of the radiator or as a member separate from theV radiator. The reservoir and surge tank provides not only expansion room for the coolant but also acts as a reservoir for the coolant, as a means for filling the cooling system, and for separating entrained air in the coolant. The reservoir portion of the reservoir and surge tank is normally located above a ba'iiie provided in the tank. Air may be drawn into the cooling system when the coolant has reached the level of the baie. Air may also be drawn into the cooling system by virture of leaks in the system. Even exhaust gas leakage into the cooling system is possibie and does occur adding to the contamination of the coolant. The present systems require considerable time to purge themselves of gas bubbles.
The invention is directed to a iiuid separating means for automatically and effectively purging gas bubbles from the coolant. The iiuid Separating means, furthermore, incorporate a reservoir for surplus coolant as well as a place for the entrained gases to collect and separate from coolant. The invention may be used between the internal combustion engine and the radiator inlet, or between the radiator outlet and the internal combustion engine.
In the preferred embodiment a venturi section is provided in the top of the liuid separating means. An opening is provided in the venturi section downstream of the most restricted part of the venturi which communicates with a liquid containing reservoir.
Another embodiment of the invention provides for the upwardly facing opening to be located in the top of a conduit which does not have a venturi section.
An object of this invention therefore is to provide an eiiective fluid separating means.
Another object of this invention is to provide a means for automatically deaerating a cooling system.
Still another object of this invention is to provide fluid separating means which has means for separating gas bubbles from a flowing liquid combined with a reservoir of liquid, and means for filling said reservoir.
Still another object is to provide a iiuid separating means in combination with a reservoir of liquid which is simple in construction, easy to manufacture, dependable in operation and relatively low in cost.
Gther objects and advantages of this invention will become more apparent when considered in connection with lthe accompanying drawings, wherein: v
FIGURE 1 is a fragmentary schematic side elevational view of a cooling system incorporating an embodiment of this invention between the mechanism to be cooled and the inlet of the radiator, and
Mice
FIGURE 2 is a sectional view taken on the plane indicated as 2 2 of FlGURE l, and
FGURE 3 is a cross sectional view of an alternate embodiment of the huid separating means shown in Elf- URE 1, and
FIGURE 4 is a fragmentary schematic side elevational View of another embodiment of this invention in which the iiuid separating means is located between the radiator outlet and the inlet of the mechanism to be cooled, and
FIGURE 5 is an alternate construction of the fluid separating means used in FGURE 4.
Referring now to the drawings and in particular FG- URES 1 and 2, a radiator is indicated generally at 19 having an inlet 11 and an outiet 12. Outlet 12 is adapted to be connected by a conduit 13 shown in part to the Water pump inlet, for example, of an internal combustion engine.
A combined fluid separator and liquid containing reservoir and surge tank is shown at 14 and includes a kconduit 16 having an inlet 17 and an outlet 1S. inlet 17 is connected to conduit 19 shown in part, which is adapted to be connected to the water pump outlet of an internal combustion engine. Outlet 13 is connected by conduit 21 to the radiator inlet 11.
The fluid separating means is provided in the conduit 16. A venturi section 22 is provided in the top portion of conduit 16 intermediate of the inlet 17 and outlet 18. An upwardly facing opening 23 is located in the venturi section 22 and extends transversely across the conduit 15 so that itcovers a distance which is substantially equal to the widest portion of the conduit 16 at the site of the opening. This insures that `all of the liquid indicated at 27 flowing through conduit 1d will pass under the upwardly facing opening 23. The upwardly facing opening 23 is located at a location downstream from the most restricted portion of the venturi 22.
A combined liquid containing reservoir and surge tank 24 is integrally connected to the top of the conduit 16 so that the upwardly facing opening 23 communicates with the inside of the combined liquid containing reservoir and surge tank 24. A filler cap 26 is located in the top of the combined liquid containing reservoir and surge tank 24 for the purpose of filling the system with coolant. The combined liquid containing reservoir and surge tank 24 extends upwardly a distance suiiicient to make it the highest part of the cooling system.
In the operation of the device, the liquid 27 containing entrained gas or air bubbles 28 is pumped downstream from the water pump outlet of the internal cornbustion engine through conduit 19, inlet 17 and into the conduit 15. Once inside conduit 15 it comes in contact with the venturi section 22. All of this time gas bubbles 28 having a density less than the liquid 27 will be rising in the liquid 27. The venturi section 22 permits an accumulation and combining of a number of the gas bubbles 28 adjacent to the surface of the venturi section 22. The gas bubbles 28 will quickly rise through the upwardly facing opening 23 as the liquid 27 flows past the upwardly facing opening 23. Gas bubbles 28 continue to rise and separate gravitationally from the quiescent liquid in the combined liquid containing reservoir and surge tank 24 until they are expelled into the air space above the liquid in the combined liquid containing reservoir and surge tank 24.
Referring now to FIGURE 3, an alternate conduit 29 is provided which has an inlet 117 and an outlet 118 connected to conduits 19 and 21. Conduit 29, however, does not have the venturi section. It does, however, have the upwardly facing opening 123 in the top of the conduit 29 which communicates in the same manner with the liquid 27 in the combined liquid containing reservoir and surge 3 tank 124. In this embodiment the gas bubbles 2S simply rise to the top of the conduit 29 and when reachnig the opening 123 separate themselves from the liquid in the conduit 29 and are received in the combined liquid containing reservoir andfsurge tank 124.
Referring now to FIGURE 4, a combined fluid separator and liquid containing reservoir conduit is indicated at 3i). The fluid separating means is provided in conduit 31. Conduit 31 is located between kthe .conduit 13 connected to the outlet 12 of the radiator 10 and the conduit 32 shown in part. Conduit 32 is connected to the water pump inlet of the internal combustion engine.
A liquid containing reservoir conduit 38 is secured to the top of the venturi section 36 so that the upwardlyV facing opening 37 communicates with the interior of the liquid containing reservoir conduit 3S.y The liquid containing reservoir conduit 38 may have its axis substantially perpendicular to the axis of the conduit 31. The liquid containing reservoir conduit 38 may be arranged however at any convenient vertical anglerto conduit 31 as long as it rises higher than the other portions of the cooling system, and furthermore that the gas bubbles 28 be permitted to rise to the surface of liquid 27. Aller cap 39 isdisposed on top of the liquid containing reservoir conduit 3S so that the liquid 27 may be added as needed by the system. Liquid containing reservoir conduit 38 also acts as an expansion chamber for the liquid 27. The operation of this embodiment is similar to the embodiment of FIGURES 1 and 2.
FIGURE discloses an alternate'embodiment to the fluid separating means shown .in FIGURE 4. 1n this em-` bodiment the conduit indicated at 41 has an inlet 133, and outlet 134 and a substantially constant cross section. Conduit 41 does not have a venturi section. Gas bubbles 2S simply rise gravitationally to the top of the conduit 41 and when reaching the upwardly facing opening 137 pass into the connes of the quiescent liquid 27 of the liquid containing reservoir conduit 138, This embodiment is similar in operation to the embodiment of FIGURE 3.
The aforementioned described cooling systems are automatically self-purging of gas bubbles as long as there is a full liquid flow through any of the described conduits 16, 29, 31 or 41. A liquid expansion chamber as well as a reservoir of coolant also is provided. The liquid coolant level may drop substantially without detriment to the cooling system operation as long as it does not drop below the level of the corresponding upwardly facing opening 23 123, 37 or 137.
The invention is adaptable to many and different cooling systems used with many and different forms of mechanisms. 1t will be understood therefore that the invention is not to be limited to the exact construction shown and described but that various changes and modiiications may be made without departing from the spirit and scope of the invention as dened in thek appended claims.Y We claim:
