摘要： Provided is a direct spray fuel injector including a bundle of opening/closing valves, wherein the bundle of opening/closing valves includes: a valve needle that is disposed within a valve housing that constitutes an exterior of the direct spray fuel injector in a lengthwise direction and that opens and closes a spray hole opened to one side of the valve housing; an electromagnetic coil that is installed at a side opposite to the spray hole of the valve needle and causes a spray hole opening/closing operation of the valve needle to be performed; an armature that is coaxially mounted on an outer circumferential surface of the valve needle to be slidable in an axial direction so as to be positioned between the valve needle and the electromagnetic coil; and a pressurizing spring that is installed to pressurize the valve needle toward the spray hole and causes the valve needle to close the spray hole in normal times, and the bundle of opening/closing valves is configured to pressurize the valve needle by the armature so that bounce generated when the valve needle in an open state approaches the spray hole so as to close the spray hole is able to be attenuated. The structure of a buffer spring that suppresses bounce generated in the valve needle when a valve is closed is simplified so that the number of components of the bundle of opening/closing valves and the number of assembling processes of the direct spray fuel injector can be reduced and manufacturing efficiency and economic feasibility of the direct spray fuel injector can be improved.

摘要： The present disclosure relates to an injection valve. The valve may comprise a fluid inlet tube with a recess, a valve body, a valve needle, a spring element, and an elastic body. The valve body may have a central longitudinal axis and a cavity with a fluid outlet portion. The valve needle may be arranged in the recess of the fluid inlet tube and movable in the cavity. The spring element and elastic body may be arranged in the recess and interact with a portion of the valve body on one side and with a spring rest fixed to the valve needle on another side. The elastic body and the spring element are compressed as the valve needle is moved along the longitudinal axis away from its closing position. The elastic body, in the presence of a fluid pressure in the recess, exerts a fluid-pressure-dependent longitudinal force on the valve needle.

摘要： The invention relates to a fuel injector for internal combustion engines for injecting fuel at high pressure, comprising a pressure chamber formed in an injector body, in which pressure chamber a nozzle needle is arranged in a longitudinally movable manner, which nozzle needle has a cone region tapered in a combustion chamber direction and a pin region having a constant diameter d23 at a combustion-chamber end of the nozzle needle. The injector body has a substantially conical nozzle needle seat, from which a first injection opening extends, and a blind hole, which adjoins the nozzle needle seat on the combustion chamber side. The blind hole has a cylindrical segment, which has the diameter d31, and a hole base, from which a second injection opening extends. The cone region of the nozzle needle interacts with the nozzle needle seat and thereby opens and closes the first injection opening and the second injection opening with respect to the pressure chamber. During a partial stroke of the nozzle needle, the first injection opening and the second injection opening are connected to each other by means of a throttle gap, which is formed in the blind hole between the pin region and the wall of the blind hole, and the throttle gap remains constant at least over the partial stroke of the nozzle needle.
