Abstract
Abstract A liquid coolant radiator for the cooling system of a heatgenerating engine and specifically an internal combustion engine with the radiator including an inlet header, an outlet header, tubes interconnecting the headers for flow of liquid in a flow path through the engine and radiator in which the radiator portion of the flow path includes the inlet header, tubes and outlet header, a tank for separating entrained gas such as air, leaked combustion gases and the like with the tank having a space for receiving the gas and from which the gas can then be vented to the atmosphere, a tube interconnecting the tank and the coolant flow path for diverting some of the coolant with the entrained gas into the tank and a fluid flow device for inducing mixed liquid and entrained gas flow into the tank as by applying a suction in order that the gas may be separated from the coolant in the tank and vented to the atmosphere without disturbing the coolant flow in the coolant flow path.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
183 words
A liquid coolant radiator for the cooling system of a heatgenerating engine, comprising: a liquid coolant inlet header; a liquid coolant outlet header; tubes interconnecting said headers for flow of mixed gas and coolant liquid in a flow path means that includes said inlet header, tubes and outlet header; fluidconfining means for separating entrained gas from coolant liquid having a gas receiver part; fluid flow means interconnecting said confining means and said flow path means; positive flow-inducing means for inducing fluid flow in said fluid flow means from said flow path means to said confining means thereby flowing mixed coolant liquid and gas into said confining means from said flow path means; an inlet conduit means to said inlet header for flow of liquid thereto from said engine; a liquid flow control thermostat open and shut valve means in said inlet conduit means for controlling fluid flow in said flow path means; and fluid conduit means from said engine to said fluid-confining means bypassing said valve for flow of fluid to the fluid-confining means from said engine even when said valve is closed.
Claim 2
Dependent Claim
183 words
A liquid coolant radiator for the cooling system of a heatgenerating engine, comprising: a liquid coolant inlet header; a liquid coolant outlet header; tubes interconnecting said headers for flow of mixed gas and coolant liquid in a flow path means that includes said inlet header, tubes and outlet header; fluidconfining means for separating entrained gas from coolant liquid having a gas receiver part; fluid flow means interconnecting said confining means and said flow path means; positive flow-inducing means for inducing fluid flow in said fluid flow means from said flow path means to said confining means thereby flowing mixed coolant liquid and gas into said confining means from said flow path means; an inlet conduit means to said inlet header for flow of liquid thereto from said engine; a liquid flow control thermostat open and shut valve means in said inlet conduit means for controlling fluid flow in said flow path means; and fluid conduit means from said engine to said fluid-confining means bypassing said valve for flow of fluid to the fluid-confining means from said engine even when said valve is closed.
Claim 3
Dependent Claim
147 words
A liquid coolant radiator for the cooling system of a heat-generating engine, comprising: a liquid coolant inlet header; a liquid coolant outlet header; tubes interconnecting said headers for flow of mixed gas and coolant liquid in a flow path means that includes said inlet header, tubes and outlet header; fluid-confining means for separating entrained gas from coolant liquid having a gas receiver part; fluid flow means interconnecting said confining means and said flow path means, said fluid flow means including a U-tube trap having an entrance connected to said fluid flow means and an exit in said fluid-confining means; positive flow-inducing means for inducing fluid flow in said fluid flow means from said flow path means to said confining means thereby flowinG mixed coolant liquid and gas into said confining means from said flow path means; and drain means for simultaneously draining said trap and said radiator.
Claim 4
Dependent Claim
147 words
A liquid coolant radiator for the cooling system of a heat-generating engine, comprising: a liquid coolant inlet header; a liquid coolant outlet header; tubes interconnecting said headers for flow of mixed gas and coolant liquid in a flow path means that includes said inlet header, tubes and outlet header; fluid-confining means for separating entrained gas from coolant liquid having a gas receiver part; fluid flow means interconnecting said confining means and said flow path means, said fluid flow means including a U-tube trap having an entrance connected to said fluid flow means and an exit in said fluid-confining means; positive flow-inducing means for inducing fluid flow in said fluid flow means from said flow path means to said confining means thereby flowinG mixed coolant liquid and gas into said confining means from said flow path means; and drain means for simultaneously draining said trap and said radiator.
Claim 5
Dependent Claim
46 words
The radiator of claim 1 wherein said positive flow-inducing means comprises aspirator means in said fluid conduit means connected to said fluid flow means for creating a suction in said fluid flow means by liquid flowing through said fluid conduit means and aspirator from said engine.
Claim 6
Dependent Claim
76 words
The radiator of claim 1 wherein said positive flow-inducing means comprises aspirator means in said fluid conduit means connected to said fluid flow means for creating a suction in said fluid flow means by liquid flowing through said fluid conduit means and aspirator from said engine and said fluid flow means comprises a tube having an entrance adjacent the top of said flow path means and an exit adjacent the top of said gas receiver part.
Claim 7
Dependent Claim
15 words
The radiator of claim 3 wherein said aspirator is positioned in said gas receiver part.
Claim 8
Dependent Claim
41 words
The radiator of claim 3 wherein there is provided a liquid trap having an entrance connected to the exit from the aspirator to receive fluid therefrom and an exit from the trap adjacent to the top of said gas receiver part.
Claim 9
Dependent Claim
46 words
The radiator of claim 2 wherein said trap is located substantially entirely in said fluid-confining means, said drain means drains said fluid-confining means, and there is provided a fluid flow opening between said fluid-confining means and said flow path means for said draining of the radiator.
Claim 10
Dependent Claim
58 words
The radiator of claim 1 wherein said fluid-confining means includes a liquid receiver part beneath said gas receiver part for buoyant separation and collection of said entrained gas in said gas receiver part, and said fluid conduit means comprises a first supply line to said gas receiver part and a second supply line to said liquid receiver part.
Claim 11
Dependent Claim
33 words
