  • Patent number: 4829965
    Abstract: An injection valve for a single suction pipe injection in the case of mixture-compressing internal-combustion engines on the ejection side by an insertion connection by means of a nozzle part is held in a wall breakthrough of the suction pipe, having a rubber elastic O-ring located in-between. In order to avoid damage to the O-ring, when the injection valve is inserted, at the processing edges of the wall breakthrough, a centering device is arranged in the free end area of the nozzle part. Preferably, the centering device is developed at a protective cap that can be arranged in the free end area of the nozzle piece.

  • Patent number: 4409934
    Abstract: An intake manifold is disclosed for 4- to 6-cylinder inline internal combustion engines. The manifold comprises a distribution chamber with essentially equally long individual intake pipes extending therefrom in two groups arranged approximately symmetrically to each other. The intake pipes have initial portions emanating from the distribution chamber approximately in one plane in pairwise mutual opposition, continuously curved intermediate portions, and mutually parallel end portions extending in the same direction with coupling ends for inlet ducts of an engine. The end portions of the intake pipes extend approximately at a right angle to the initial portions and substantially in a plane approximately parallel to the plane of the initial portions thereof.
