    摘要: A fluid dosing device for a pressurized liquid is disclosed, which comprises a chamber (35) which is supplied with pressurized liquid by means of a liquid supply line (17, 19); a valve needle (9) which is guided through the chamber (35), the first end section of said valve needle being able to be lifted and the second end section thereof forming a valve in conjunction with a valve seat disposed on the housing (3). Metal bellows (33) are provided as a leadthrough element for the first end section of the valve needle (9). The metal bellows seal the chamber in said region in a tight manner. A throttle point (37, 39) is provided between the valve needle (9) and the inner wall of the chamber between the metal bellows (33) and the mouth (18) of the liquid supply line (17) leading into the chamber.

    摘要: A fuel injector comprises a body having a longitudinal axis, an length-changing actuator that has first and second ends, a closure member coupled to the first end of the length-changing actuator, and a compensator assembly coupled the second end of the actuator. The length-changing actuator includes first and second ends. The closure member is movable between a first configuration permitting fuel injection and a second configuration preventing fuel injection. And the compensator assembly axially positions the actuator with respect to the body in response to temperature variation. The compensator assembly utilizes a configuration of at least one spring disposed between two pistons so as to reduce the use of elastomer seals to thereby reduce a slip stick effect. Also, a method of compensating for thermal expansion or contraction of the fuel injector comprises providing fuel from a fuel supply to the fuel injector; and adjusting the actuator with respect to the body in response to temperature and other dimensional variations.

    摘要: An injection valve for injecting fuel comprises a valve housing (1) inside of which a drive unit (15) controls the movement of a valve needle (5) that is pretensioned by a spring (11). The injection valve also comprises a main chamber (27), which is provided inside the valve housing, is filled with fuel and accommodates the valve needle (5), and comprises a hydraulic bearing for the drive unit (15). The hydraulic bearing has a hydraulic chamber (29) that is connected to the main chamber (27), whereby fuel serves as the operating substance of the hydraulic bearing.
