Plastic fuel line suction unit with integral undercut hose union and moulding process

A process is claimed for manufacturing a plastic component with a hollow cylindrical union (20) in one wall having one or more undercuts perpendicular to the demoulding direction of one (30) of the moulding tool parts. For easier removal of the undercut part a core(32) for forming the internal chamber (22) of the union (20) is retracted before the surrounding tool part (30) allowing the undercut area to be elastically deformed into the hollow chamber (22) as the tool part is retracted. Also claimed is a plastic component with an integral suction hose union manufactured by the above process. The union (20) is injected in one piece with the suction unit (12) and the undercut, which forms a positively interlocking attachment for a hose on the union, is formed by an annular bulge (28). A second union (24) is injected around the union (20) and the undercut extends into an annular chamber (26) between the unions (20, 24). Both core (32) and tool part (30) are retracted in the same direction.

INDUCTION SYSTEM, ESPECIALLY FOR USE AS AN INDUCTION PORT OFAN INTERNAL COMBUSTION ENGINE

The invention relates to an induction port with an optimal noise level, especially a suction pipe for use as an induction port of an internal combustion engine. The noise level is optimised by introducing shunt resonators (16, 18) in the collecting chamber (12) of the suction pipe. Said suction pipe is produced using a multi-shell technique. The inserted structures (16, 18) can be stuck or welded before the shells are joined. The inventive shunt resonators (16, 18) require little space and can also be used for subsequently optimising the suction pipes in the test phase, should the test results be acoustically unsatisfactory.

Manufacturing method of intake manifold

Intake passage of an internal combustion engine

Valve assembly having a sealing member

A valve assembly is disclosed that includes a first and a second valve assembly parts that collectively define a duct. The valve assembly also includes a valve unit that includes a housing defining a fluid flow path therethrough. The valve unit is coupled to the first valve assembly part such that the fluid flow path is in fluid communication with the duct. A control valve is also included for controlling flow of fluid in the flow path. Furthermore, the valve assembly includes a sealing member that seals a space between the first valve assembly part and the second valve assembly part, that seals a space between the first valve assembly part and the valve unit, and that dampens vibration transmitted to the valve unit.
