Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 189 words
A cooler-cum-blower assembly in internal combustion engines, in particular for automative engines, comprising a water-cooler including two upright cooler elements located in front of a front end of the internal combustion engine opposite each other in relation to a longitudinal median plane of the engine, each of the cooler elements forming an acute angle with said longitudinal median plane on the side facing away from the engine, an axial blower actuated by the engine and arranged in front of the two cooler elements, said axial blower comprising a blower shaft, a blower impeller mounted thereon, and an outer ring encompassing the blower impeller, further comprising a central bracket attached to said front end of the engine, a bearing for the blower shaft located on the central bracket, an intermediate housing attached to said central bracket and extending from the cooler elements as far as the axial blower, said intermediate housing closing the space between the cooler elements and the blower in an upward and downward direction and comprising a flange on its side facing away from the engine, said outer ring of the blower being attached to said flange.
Claim 2
Dependent Claim 189 words
A cooler-cum-blower assembly in internal combustion engines, in particular for automative engines, comprising a water-cooler including two upright cooler elements located in front of a front end of the internal combustion engine opposite each other in relation to a longitudinal median plane of the engine, each of the cooler elements forming an acute angle with said longitudinal median plane on the side facing away from the engine, an axial blower actuated by the engine and arranged in front of the two cooler elements, said axial blower comprising a blower shaft, a blower impeller mounted thereon, and an outer ring encompassing the blower impeller, further comprising a central bracket attached to said front end of the engine, a bearing for the blower shaft located on the central bracket, an intermediate housing attached to said central bracket and extending from the cooler elements as far as the axial blower, said intermediate housing closing the space between the cooler elements and the blower in an upward and downward direction and comprising a flange on its side facing away from the engine, said outer ring of the blower being attached to said flange.
Claim 3
Dependent Claim 59 words
A cooler-cum-blower assembly according to claim 1, further including a first vee-belt pulley arranged on one free extremity of the crankshaft of the internal combustion engine, a second vee-belt pulley mounted on said blower shaft at an extremity of the blower shaft opposite the blower impeller and drivingly connected with said first vee-belt pulley by means of a vee-belt.
