  "textContent": "The needle has fluid entrance and exit openings for a fluid passage. A cylindrical section is placed between the openings to provide a closed sliding fit of the needle in a valve cartridge. A calibration unit (32) e.g. a pin, is inserted into an axially extending opening. The calibration unit seals the extending opening, and influences the fluid passage through the needle based on an insertion depth of the calibration unit. Independent claims are also included for the following: (a) a metering device for dosing pressurized fluids for a fuel injection system in an internal combustion engine (b) a method of controlling a metering device.",
