摘要： The invention relates to a piston fuel pump (18) for an internal combustion engine comprising a pump cylinder (40) and a pump piston (28) which can be axially displaced in the pump cylinder (40) and comprising a working chamber (34) defined by the pump piston (18). A seal (46) is provided on the pump cylinder (28) which seals the working chamber (34) counter to a low pressure region, characterized in that the seal (46) is applied directly to the pump piston (28) by means of an injection moulding method.

摘要： Injection molded parts having at least one thermoplastic insert and a thermoplastic composite element molded onto the insert are already known, wherein the at least one insert has multiple raised areas configured as fusing points, which are successively disposed in the melt flow direction at the boundary thereof to the composite element. The injection molded part is produced by means of an injection molding method, during which the insert is disposed in an injection molding tool and a composite element is integrally molded thereon. The raised areas are to be fused from the melt of the composite element such that a bonded, gas-tight connection is obtained. The invention provides that the at least one raised area (8) has a first slant (12) on the melt flow side (11) thereof, wherein the ratio of the height (H2) of the constricted cross-section (10) to the height (HI) of the raised area (8) is in the range between 0.6 and 0.9.
