Abstract
Abstract In a motor vehicle a water-cooled internal combustion engine serving as the driving engine is enclosed by a sound-absorbing capsule partly formed by the surrounding parts of the vehicle. At the front wall of this capsule a housing is provided to receive the air flowing off from the radiator, from which housing a closed air duct passes through the capsule, leading into the outside at one of the other capsule walls.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
A motor vehicle, comprising a water-cooled internal combustion driving engine transversely mounted and having a flange-mounted gearbox, a radiator and an associated fan, walls defining a completely enclosed, sound-absorbing capsule containing said engine and said gearbox, said walls being at least partly formed by surrounding parts of the vehicle and a top comprising an engine hood of the vehicle, and one of said walls comprising a separate bottom plate at the lower side of said capsule, a separate housing located within said capsule for receiving cooling air flowing off from said radiator, said housing being closed relative to the interior of said capsule and comprising part of a front wall of said capsule, an air duct located within said capsule and being closed relative to the interior of said capsule, said air duct being partly formed by at least one section of the walls of said surrounding capsule and being in open communication with said housing for carrying the outflow of cooling air and leading from said housing to the outside of said capsule through another of said walls thereof, and said air duct extending through said capsule, adjacent a cylinder block of said engine and lying above said gearbox.
Claim 2
Dependent Claim
200 words
A motor vehicle, comprising a water-cooled internal combustion driving engine transversely mounted and having a flange-mounted gearbox, a radiator and an associated fan, walls defining a completely enclosed, sound-absorbing capsule containing said engine and said gearbox, said walls being at least partly formed by surrounding parts of the vehicle and a top comprising an engine hood of the vehicle, and one of said walls comprising a separate bottom plate at the lower side of said capsule, a separate housing located within said capsule for receiving cooling air flowing off from said radiator, said housing being closed relative to the interior of said capsule and comprising part of a front wall of said capsule, an air duct located within said capsule and being closed relative to the interior of said capsule, said air duct being partly formed by at least one section of the walls of said surrounding capsule and being in open communication with said housing for carrying the outflow of cooling air and leading from said housing to the outside of said capsule through another of said walls thereof, and said air duct extending through said capsule, adjacent a cylinder block of said engine and lying above said gearbox.
Claim 3
Dependent Claim
30 words
A motor vehicle as in claim 1, further comprising wheelguards, wherein said air duct bends sideways and opens into said wheelguard of said vehicle on the side of said gear-box.
Claim 4
Dependent Claim
55 words
A motor vehicle as in claim 1, having a splashboard serving as the rear wall of said capsule, wherein an additional wall is provided in front of said splashboard, and wherein said air duct opens into a chamber located between said splashboard and said additional wall, which is open at the bottom of the vehicle.
Claim 5
Dependent Claim
22 words
A motor vehicle as in claim 3, further comprising flexible elements for supporting said additional wall against said splashboard of said vehicle.
Claim 6
Dependent Claim
15 words
A motor vehicle as in claim 1, wherein said air duct comprises a flexible hose.
Claim 7
Dependent Claim
36 words
A motor vehicle as in claim 1, wherein a bottom of said housing of said radiator/fan assembly is provided with a flap leading to the outside which opens automatically once a given dynamic pressure is exceeded.
Claim 8
Dependent Claim
22 words
A motor vehicle as in claim 1, wherein said fan is located at that end of said air duct adjacent said housing.
Claim 9
Dependent Claim
40 words
A motor vehicle as in claim 1, wherein said fan is located in front of said radiator of said combustion engine and wherein an additional air outlet opening is provided at a bottom of said housing leading into the outside.
Claim 10
Dependent Claim
42 words
A motor vehicle as in claim 8, wherein a spoiler is provided on a lower front edge of said engine hood for producing a partial vacuum at higher vehicle velocities in the area of said lower air outlet opening of said housing.
Claim 11
Dependent Claim
40 words
A motor vehicle as claimed in claim 1, wherein said housing is provided with at least one flap leading to said air duct, said flap opening automatically once a given dynamic pressure is exceeded so as to bypass said fan.
