Abstract A radiator apparatus as a part of the cooling system for an engine in which the apparatus comprises spaced vertical inlet and outlet tanks with a core having coolant tubes extending horizontally between the tanks (such radiator being termed a ''''crossflow radiator''''), a first coolant conduit from the engine to a first of the tanks, a second coolant conduit from the second of the tanks to the engine so that the coolant flows from the engine to one tank or header and through the tubes to the other tank or header and then back to the engine, a coolant reserve and deaerating third vertical tank having a coolant liquid level when in use intermediate the top and bottom of this third tank, an inlet line for the coolant and entrapped gases from the engine to this third tank, a coolant outlet line for coolant substantially free of entrapped gases from the third tank to the engine and a check valve in the coolant inlet line permitting fluid flow only toward the third tank.
The apparatus of claim 1 wherein said outlet line is connected to said third tank adjacent the bottom thereof.
Claim 2
Dependent Claim
53 words
The apparatus of claim 1 wherein said coolant outlet line from said third tank comprises a flow opening between said outlet second tank and third tank adjacent said second coolant conduit from said second tank so that liquid from said third tank flows through said opening into and through said second coolant conduit.
Claim 3
Dependent Claim
50 words
The apparatus of claim 3 wherein said outlet second tank and said third tank are separated by a partition wall in which said flow opening is located, said flow opening and second coolant conduit both being located adjacent the bottoms of said second and third tanks and said partition wall.
Claim 4
Dependent Claim
166 words
In a cooling system for an engine, apparatus comprising: an engine; an inlet first radiator tank; an outlet second radiator tank spaced therefrom; a core with coolant tubes extending between said tanks; a first coolant conduit from said engine to said first tank; a second coolant conduit from said second tank to said engine; a coolant reserve and deaerating third tank having a coolant liquid level therein when in use intermediate the top and bottom of the third tank and having a pressure relief valve above the liquid level; an inlet line for coolant and gases from said engine to said third tank; a coolant outlet line for coolant substantially free of entrapped gases from said third tank to said engine; a one-way flow device in said coolant inlet line permitting fluid flow only toward said third tank; and flow means in the upper portion of said second tank between said second tank and said third tank for permitting fluid flow only toward said third tank.
Claim 5
Dependent Claim
24 words
The apparatus of claim 5 wherein said third tank is adjacent said second tank with a common wall between the third and second tanks.
