Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
192 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector, which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space.
Claim 2
Dependent Claim
192 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector, which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space.
Claim 3
Dependent Claim
24 words
Induction pipe according to claim 1 in which the wall extends perpendicular to the inflow direction over an entire inside diameter of the pipe.
Claim 4
Dependent Claim
38 words
Induction pipe according to claim 1, in which the wall, starting out from an inside wall of the induction pipe, extends over one-fourth to one-half the inside diameter of the induction pipe and perpendicular to the inflow direction.
Claim 5
Dependent Claim
221 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space, said induction pipe further comprising adjusting means for the wall by means of which the wall can be moved more or less into the path of the inflowing mixture.
Claim 6
Dependent Claim
221 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space, said induction pipe further comprising adjusting means for the wall by means of which the wall can be moved more or less into the path of the inflowing mixture.
Claim 7
Dependent Claim
236 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space, said induction pipe further comprising adjusting means for the wall by means of which the wall can be moved more or less into the path of the inflowing mixture, the wall being formed by a slide valve which is connected with a rod system.
Claim 8
Dependent Claim
236 words
Induction pipe for the mixtures for internal combustion engines with at least three cylinders, comprising a distributor section, an inlet defining a horizontally extending path for the mixture flowing into the distributor section, at least one first supply line for the mixture horizontally branching off from the distributor section and leading to at least one first cylinder, at least one second supply line for the mixture horizontally branching off from the distributor section between the inlet and the first supply line at the same height as the first supply line and leading to at least one second cylinder, and a deflector which runs between the first and second supply lines and transversely to the path of the mixture flowing into the distributor section, for evening the richness of fuel in portions of the mixture flowing into each of the first and second supply lines, the deflector being formed by a wall so narrow that between its side edges on the one hand and intermediate walls lying in alignment therewith and disposed between the first and second supply lines for the mixture on the other hand, there will remain a free distance space, said induction pipe further comprising adjusting means for the wall by means of which the wall can be moved more or less into the path of the inflowing mixture, the wall being formed by a slide valve which is connected with a rod system.
