摘要： The invention relates to a dosing device comprising a housing (1) provided with an actuator, a dosing opening (8), a guiding shaft (6) which surrounds part of the valve needle (7) and forms a valve chamber (10) with the same, and a fluid chamber module (4) which is welded to the housing (1) in the form of a duct for guiding the valve needle (7) into the housing (9). The fluid chamber module (4) and the housing (1) are assembled along a separation surface (13) which is subjected to pressure by the dosing liquid and is formed almost only by axial cylinder wall surface parts (13) in order to reduce the pressure load on the weld seam (13).

摘要： The invention relates to an actuator (4) which is connected, on one side, to a valve needle (3), and on the opposite side, to a hydraulic piston (6) pertaining to a hydraulic length compensator. A working chamber (5) is divided by a tight separating membrane (9), into an actuator chamber (10) containing the actuator (4) and a fluid chamber (11) which can be filled with the fluid to be dosed in a pressurised manner while the actuator chamber (10) and the hydraulic chamber (7) are filled with a hydraulic fluid. A base pressure can be produced in the hydraulic fluid by means of the pressure of the fluid to be dosed, which is transmitted through the separating membrane (9).

摘要： The dosing device has an inner injector body (21) receiving an injector driving mechanism (5). An envelope (2) surrounds the inner injector body at least partly radially so that a circumferential gap-shaped storage volume (12) is formed between them, which is fluidically connected in an unthrottled manner to an injection nozzle (10) and a fuel connection (14). Said device is particularly suitable as fuel direct injector in order to reduce pressure variations during opening.

摘要： The valve unit (1) comprises, in its most essential form: a hollow-cylindrical housing (2) whose interior is sealed on both sides by a respective membrane (8, 9), and the housing wall is provided with an inlet (5) and an outlet (4) for a fluid; a cylindrical flow restrictor (3), which can be axially displaced inside the housing interior, is adjoined via its end faces to said membranes (8, 9), and which consists of a central pin (3.1) that, in at least one area, has an enlarged cross-section (3b, 3c, 3f), whereby at least two surfaces (3d) that are, in essence, axially oriented are formed in said area, and; two valve seat surfaces (6A), which are formed on the housing inner wall and of which at least one of the valve seat surfaces (6A) and/or at least one axial surface (3d) of the enlarged cross-section of the flow restrictor (3b, 3c, 3f) are/is provided with fluid channels (3e). The at least one area of the enlarged cross-section of the flow restrictor (3b, 3c, 3f) interacts with the valve seat surfaces (6A) according to the position of the flow restrictor (3). The flow restrictor (3) can be subjected to the action of a stroke, which acts from the outside and which can be initiated by an actuator (11) via a membrane (8, 9) and, at the same time, the flow restrictor can be subjected to the action of a restoring force, which also acts from the outside and which can be initiated by a restoring spring or by an actuator (10) via a membrane (8, 9). The method for producing a valve unit comprises the following steps: producing a crude hollow-cylindrical housing; producing a valve seat in the form of a ring; inserting, attaching and positioning at least one valve seat in the interior of the housing; inserting a portion of a flow restrictor inside the housing so that a surface of the enlarged cross-section of the flow restrictor rests against a valve seat; inserting a second valve seat in order to clamp the flow restrictor or; placing one end of the flow restrictor having an enlarged cross-section onto the central pin in order to clamp the valve seat, and; fixing the membranes to the faces of the housing. The valve unit is optimally used in a dosing device, whereby the operating mode of the valve unit normally opened or normally closed can be incorporated in a dosing device without subjecting the valve unit to additional subsequent finishing.

摘要： The invention relates to a fluid dosing device for a pressurized liquid, comprising a chamber (35) which is arranged in a housing (3) and which is supplied with pressurized liquid by means of a liquid supply line (17, 19); in addition to 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 which is connected to the chamber (35), in conjunction with a valve seat disposed on the housing (3). In order to provide a tight and enduring leadthrough for the valve needle, metal bellows (33) are provided as a leadthrough element for the first end section of the valve needle (9) when seen from the chamber (35) in an outward direction. 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.
