Abstract
Abstract A cooling system for an engine including a radiator for cooling a liquid circulated between the engine and the radiator, the radiator having a plurality of sections interconnected through conduits which pass externally between the radiator sections, the conduits thus being accessible for selective closing of a conduit or re-routing thereof to isolate one radiator section from the others and thereby enable continued operation of the remaining portions of the radiator despite the presence of a puncture in that one section. An auxiliary heat exchanger is supplied with cooled liquid passing from the radiator to the engine and includes a continuous annular chamber for receiving fluid to be cooled by the liquid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A cooling system for an engine including a radiator for cooling a liquid coolant passed from the engine through the radiator and capable of functioning despite the presence of a puncture in the radiator, said radiator comprising: at least two radiator sections, each radiator section having opposite headers and liquid-conducting tubes extending between said opposite headers; means interconnecting corresponding headers of adjacent sections, said means including a common flow path and a plurality of liquid-conducting conduits, one end of each of which is connected to each of said adjacent sections, respectively; and the other end of each of which is connected to the common flow path; and diverting means interposed between said headers and said common flow path for selectively diverting liquid coolant from at least one of said sections to selectively isolate that one section from the remainder of the radiator such that the radiator will function despite the presence of a puncture in said one section, said diverting means including a valve forming a conduit, said valve comprising a normally collapsed inflatable gate member within said conduit and means for admitting air under pressure into said gate member to inflate said member and close-off said conduit to the passage of liquid coolant.
Claim 2
Dependent Claim
204 words
A cooling system for an engine including a radiator for cooling a liquid coolant passed from the engine through the radiator and capable of functioning despite the presence of a puncture in the radiator, said radiator comprising: at least two radiator sections, each radiator section having opposite headers and liquid-conducting tubes extending between said opposite headers; means interconnecting corresponding headers of adjacent sections, said means including a common flow path and a plurality of liquid-conducting conduits, one end of each of which is connected to each of said adjacent sections, respectively; and the other end of each of which is connected to the common flow path; and diverting means interposed between said headers and said common flow path for selectively diverting liquid coolant from at least one of said sections to selectively isolate that one section from the remainder of the radiator such that the radiator will function despite the presence of a puncture in said one section, said diverting means including a valve forming a conduit, said valve comprising a normally collapsed inflatable gate member within said conduit and means for admitting air under pressure into said gate member to inflate said member and close-off said conduit to the passage of liquid coolant.
Claim 3
Dependent Claim
28 words
The invention of claim 1 wherein said external conduits are selectively disconnectable from said respective headers to enable selective removal and replacement of a section within the radiator.
Claim 4
Dependent Claim
20 words
The invention of claim 1 wherein said normally collapsed inflatable gate member comprises a bladder disposed within said gate member.
Claim 5
Dependent Claim
22 words
The invention of claim 1 wherein each of said valves is in communication with a plurality of liquid-conducting tubes via said headers.
