摘要： A fuel injector, especially for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a nozzle body able to be inserted into a recess of a cylinder head, a valve housing, a plug abutting the valve housing, and at least one fixation element, which fixes the nozzle body in its position in the recess, the fixation element extending from a connection region (28) between the valve housing and the plug on the spray-discharge side. The at least one fixation element has a reinforcement having a spherical contour at an outer periphery, the reinforcement being formed by at least one outwardly projecting element having an outwardly curving end face and/or having a planar end face.

摘要： Leakage of a combustion gas is prevented by installing a seal ring in an annular groove provided in the outer peripheral surface of a fuel injection valve. Further, a combustion gas leaked from the seal ring is sealed in by providing a seal washer more on the rear end side of the fuel injection valve than the seal ring. Thus a combustion gas seal for an injection valve is provided, and the combustion gas seal is capable of exhibiting excellent sealing ability for a long term with a simple structure.

摘要： An injector for directly injecting fuel into a cylinder of an internal combustion engine having a socket. The injector is provided with a nozzle insertable into the socket. An annular gap is defined between the nozzle and the socket when the nozzle is received in the socket. A first seal groove, formed in the nozzle, receives a first gas seal that seals the annular gap. A second seal groove, formed in the nozzle, receives a second gas seal that seals the annular gap. The second seal groove is formed closer to the distal end of the nozzle than the first seal groove. The depth of the second seal groove is greater than that of the first seal groove. This structure prevents the formation of deposits and maintains the sealing capability of the gas seals without lowering installation and maintenance efficiency.
