  • Patent number: 10001100
    Abstract: A valve assembly for a fluid injector for an internal combustion engine includes a valve body with a valve recess, a central longitudinal axis, and a first axial end and a second axial end with respect to the central longitudinal axis. A valve needle is axially moveable within the valve recess with respect to the central longitudinal axis. In concurrence with a seal seat area the valve needle prevents a fluid flow through at least one flow hole in its closing position and otherwise enables it. Furthermore, the injector comprises a sac volume step adjacent to the seal seat area forming a part of an inner surface of a wall of the valve body and a sac volume being designed as one end of the valve recess and being limited by a further part of the inner surface of the wall of the valve body.

  • Patent number: 7896263
    Abstract: A fluid injector has an actuator unit, a cartridge, which has a recess, which on one of its open ends forms an injection nozzle and takes in a needle. The needle has a first and a second part (15, 17). The first part (15) is inserted into the recess and closes or opens the injection nozzle depending on the position of the first part (15). The second part (17) is coupled to the actuator unit on one of its free ends and is coupled to the first part (15) via a coupling unit. The coupling unit is arranged in positive connection to the first part (15) and is joined to the second part. In that way the material for the first part may be chosen for being highly wear resistant. On the other hand the material of the second part (17) may be chosen for being well-suited for a joining process.

  • Patent number: 7832656
    Abstract: A fluid injector has a housing, a valve body and an actuator unit inserted into the housing. The valve body has a cartridge with a recess that takes in a needle. The valve body further has a hollow body arranged in a fixed position to the needle and forming a first spring rest. The valve body further has a valve cap, which takes in the cartridge and forms a second spring rest. A return spring rests on the first spring rest and on the second spring rest. The valve cap, the housing and the cartridge are formed such, that before the valve cap and the housing and the valve cap and cartridge are permanently fixed to each other the valve cap is moveable relative to the housing and the cartridge while the housing and the cartridge stay in a fixed position relative to each other.

  • Publication number: 20060108452
    Abstract: A valve for injecting fuel has a valve body (4), in which a recess is embodied. The recess widens in a downstream side region (11) to a separation edge. The valve further comprises a valve needle which is arranged in the recess and has a closing element (14). In a closed position the closing element (14) seats on a valve seat (18) and blocks or else releases the flow. The closing element (14) is embodied such that a gap (19) is embodied between the valve body (4) and the closing element (14) downstream of the valve body (4), the gap comprising a gap angle (?), a gap length (l) and a maximum gap width (s). The gap angle (?) and the gap length (1) are embodied such that in the closed position, the maximum gap width (s) is at least as large as a surface roughness of the valve body (4) or of the closing element (14) and that the maximum gap width (s) amounts to a maximum of 10 micrometers.
