Abstract
Abstract A deaeration system for a cross-flow radiator requiring continuous deaeration utilized with an internal combustion engine, wherein the radiator includes a vertical inlet tank and a vertical outlet tank connected by a tube and fin core. A generally vertical baffle divides the outlet tank into two compartments, one of which functions as a receiver tank for the core while the other compartment functions as a reservoir tank having a filler neck for a cap and pressure relief valve communicating therewith, and the radiator fluid outlet communicates with the reservoir tank adjacent the bottom thereof.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
108 words
A deaerating radiator comprising a core having a plurality of parallel tubes extending horizontally, a first vertical tank communicating with the first ends of the horizontal tubes, a second vertical tank communicating with the opposite ends of said tubes, a fluid coolant inlet communicating with said first tank and a fluid coolant outlet communicating with said second tank, a baffle in the second tank dividing the tank into a receiver tank adjacent the core and a reservoir tank, said baffle being slightly inclined upwardly away from the core and having perforations in a portion thereof, and a filler neck in said second tank and having a depending extension.
Claim 2
Dependent Claim
108 words
A deaerating radiator comprising a core having a plurality of parallel tubes extending horizontally, a first vertical tank communicating with the first ends of the horizontal tubes, a second vertical tank communicating with the opposite ends of said tubes, a fluid coolant inlet communicating with said first tank and a fluid coolant outlet communicating with said second tank, a baffle in the second tank dividing the tank into a receiver tank adjacent the core and a reservoir tank, said baffle being slightly inclined upwardly away from the core and having perforations in a portion thereof, and a filler neck in said second tank and having a depending extension.
Claim 3
Dependent Claim
23 words
A deaerating radiator as set forth in claim 1, in which said fluid outlet is positioned adjacent the bottom of said reservoir tank.
Claim 4
Dependent Claim
30 words
A deaerating radiator as set forth in claim 1, including an engine vent port in the second tank communicating with said receiver tank intermediate the upper and lower ends thereof.
Claim 5
Dependent Claim
24 words
A deaeration radiator as set forth in claim 1, including a curved deflector adjacent the core on the upper wall of said second tank.
Claim 6
Dependent Claim
24 words
A deaerating radiator as set forth in claim 1, in which said fluid inlet is positioned adjacent the upper end of said first tank.
Claim 7
Dependent Claim
44 words
A deaerating radiator as set forth in claim 2, in which said receiver tank receives fluid from the core in a turbulent state, and said reservoir tank allows the entrapped gases to separate from the fluid therein which is in a relatively quiescent state.
Claim 8
Dependent Claim
84 words
A deaerating radiator as set forth in claim 1, in which said fluid inlet is located adjacent the upper end of said first tank, said fluid outlet is positioned adjacent the lower end of the reservoir tank in said second tank, said baffle having perforations in the upper portion thereof, an engine vent port positioned intermediate the ends of said second tank and communicating with said receiver tank, and a pressure cap having a pressure relief valve therein adapted to close said filler neck.
Claim 9
Dependent Claim
31 words
A deaerating radiator as set forth in claim 7, including a curved deflector at the upper end of said second tank adjacent the core to deflect entrapped gases through said baffle.
Claim 10
Dependent Claim
207 words
A deaerating radiator comprising a core having a plurality of parallel tubes extending horizontally, a first vertical tank communicating with the first ends of the horizontal tubes, a second vertical tank communicating with the opposite ends of said tubes, a fluid coolant inlet communicating with the upper end of said first tank and a fluid coolant outlet communicating with said second tank, a baffle in said second tank inclined upwardly away from said core dividing the tank into a receiver tank adjacent the core and a reservoir tank, said baffle having perforations in the upper portion thereof, a curved deflector at the upper end of said second tank adjacent the core to deflect entrapped gases through said baffle, said fluid outlet being positioned adjacent the lower end of the reservoir tank, an engine vent port positioned intermediate the ends of said second tank and communicating with said receiver tank, a filler neck in said second tank and having a depending extension, and a pressure cap having a pressure relief valve therein adapted to close said filler neck, the coolant fluid being in a turbulent state from said core in said receiver tank and separated from the entrapped gases and in a quiescent state in said reservoir tank.
Claim 11
Dependent Claim
207 words
A deaerating radiator comprising a core having a plurality of parallel tubes extending horizontally, a first vertical tank communicating with the first ends of the horizontal tubes, a second vertical tank communicating with the opposite ends of said tubes, a fluid coolant inlet communicating with the upper end of said first tank and a fluid coolant outlet communicating with said second tank, a baffle in said second tank inclined upwardly away from said core dividing the tank into a receiver tank adjacent the core and a reservoir tank, said baffle having perforations in the upper portion thereof, a curved deflector at the upper end of said second tank adjacent the core to deflect entrapped gases through said baffle, said fluid outlet being positioned adjacent the lower end of the reservoir tank, an engine vent port positioned intermediate the ends of said second tank and communicating with said receiver tank, a filler neck in said second tank and having a depending extension, and a pressure cap having a pressure relief valve therein adapted to close said filler neck, the coolant fluid being in a turbulent state from said core in said receiver tank and separated from the entrapped gases and in a quiescent state in said reservoir tank.
Claim 12
Dependent Claim
38 words
A deaerating radiator as set forth in claim 9, in which said extension has vent openings therein adapted to be located above the fluid coolant level in the reservoir tank to vent trapped gases into said filler neck.
Claim 13
Dependent Claim
34 words
A deaerating radiator as set forth in claim 7, in which said engine vent port is under the fluid level of the filled radiator to create a fluid lock upon shut-down of the system.
