Abstract
Abstract Known cooling systems exhibit separate radiators (3), compensator reservoirs (2) and fan shrouds (1). These parts must all be mounted separately, then, and as they are generally placed at various locations in the vehicle, connecting hoses must be led from the various mounting places to the internal-combustion engine. In accordance with the invention, the compensator reservoir (2) and the fan shroud (1) are fabricated in one piece and made as a support for the radiator (3). Thus, only one part need be mounted on the vehicle or on the internal-combustion engine, and only one hose run need be provided to connect the cooling system to the internal-combustion engine.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
62 words
Cooling system for internal-combustion engines, exhibiting at least a radiator (3), a fan shroud (1) positioned for directing air through said radiator (3) and a compensator reservoir (2), operable to communicate with said radiator, characterized by the fact that the compensator reservoir (2) and the fan shroud (1) are fabricated in one piece and made as a support for the radiator (3).
Claim 2
Dependent Claim
62 words
Cooling system for internal-combustion engines, exhibiting at least a radiator (3), a fan shroud (1) positioned for directing air through said radiator (3) and a compensator reservoir (2), operable to communicate with said radiator, characterized by the fact that the compensator reservoir (2) and the fan shroud (1) are fabricated in one piece and made as a support for the radiator (3).
Claim 3
Dependent Claim
56 words
Cooling system in accordance with claim 1, characterized by the fact that, at the geodetically lowest point of the support, there is arranged a hole (9) opening to the environment and closable with a screw plug (11), which hole is connected to the interior of the compensator reservoir (2) and the interior of the radiator (3).
Claim 4
Dependent Claim
41 words
Cooling system in accordance with claim 2, characterized by the fact that the screw plug (11), when in a screwed-in position, closes off the interior of the compensator reservoir (2) from the interior of the radiator (3) and from the environment.
Claim 5
Dependent Claim
62 words
Cooling system in accordance with claim 2 or 3, characterized by the fact that the screw plug (11), when in a vent position, opens up a connection between the interior of the compensator reservoir (2) and the interior of the radiator (3) and closes off the interior of the compensator reservoir (2) and the interior of the radiator (3) from the environment.
