摘要： A pressure atomizer includes a body having a central axis, and defining a chamber. The body further defines a connecting passage that fluidly connects the chamber to an exterior of the body. The connecting passage has an inside surface. A substantially cylindrical separator collar is disposed concentrically within the connecting passage, and includes an inside surface and an outside surface. At least a portion of the outside surface is disposed a predetermined distance from the inside surface of the connecting passage to thereby define an outer fluid passageway. The outer fluid passageway extends from the chamber to a first exit point. A pintle is disposed substantially concentrically within the separator collar. The pintle includes an outside surface that is disposed a predetermined distance from the inside surface of the separator collar to thereby define an inner fluid passageway. The inner fluid passageway extends from the chamber to a second exit point.

摘要： An anti-bounce needle valve for a fuel injector, wherein the needle inherently incorporates the anti-bounce feature. The needle has a conventionally configured exterior for interfacing with a valve seat and a tip body of a conventional fuel injector. The needle is characterized by a needle body having an interior cavity which is filled with small diameter shot, preferably generally spherical tungsten carbide shot. In operation, when the needle impacts upon the valve seat at the conclusion of a fuel injection process, the shot causes the needle collision with the valve seat to be inelastic, thereby eliminating needle bounce.

摘要： A fuel injection valve for internal combustion engines, having a valve body (1) in which a bore (3) is embodied that has a longitudinal axis (14), and on the end toward the combustion chamber of which bore a valve seat (17) is embodied. In the region of the valve seat (17), at least one injection opening (20) is disposed that connects the bore (3) with the combustion chamber of the engine. A valve member (5) is disposed longitudinally displaceably in the bore (3) and with a sealing face (15) cooperates with the valve seat (17) for controlling the at least one injection opening (20). Between the wall of the bore (3) and the valve member (5), a pressure chamber (10) is embodied that can be filled with fuel at high pressure. The valve body (1) is surrounded, in the region of the pressure chamber (10), by a sleeve (22) that has anisotropic strength properties, so that the valve body (1) exhibits less deformation from the pressure in the pressure chamber (FIG. 1).

摘要： A fuel injector for an internal combustion engine is disclosed. The fuel injector includes a housing, a valve seat, a metering orifice, and a needle. The housing has an inlet, an outlet, and a longitudinal axis extending therethrough. The valve seat is disposed proximate the outlet and includes a passage having a sealing surface and an orifice. The metering orifice is located at the outlet and has a plurality of metering openings extending therethrough. The needle is reciprocally located within the housing along the longitudinal axis between a first position wherein the needle is displaced from the valve seat, allowing fuel flow past the needle, and a second position wherein the needle is biased against the valve seat, precluding fuel flow past the needle. A generally annular channel is formed between the valve seat and the metering orifice. The channel tapers outwardly from a large height to a smaller height toward the orifice openings. A method of generating turbulence in a fuel flow through a fuel injector is also disclosed.

摘要： In a dynamic flow rate adjusting method, a press-fitting degree of an adjusting pipe is adjusted to regulate a load applied to a needle by a spring in a direction for closing an injection hole. Thus, a dynamic injection quantity of an injector is adjusted. An injection command signal having one-minute long pulse width is applied to the injector to measure a static flow rate, from which the press-fitting degree is calculated. Thus, the press-fitting degree, in which variation in the static flow rate is taken into consideration, can be calculated. Therefore, variation in the dynamic flow rate of each injector, which is calculated from the press-fitting degree, includes only a dynamic flow rate error, while a static flow rate error is eliminated from the variation in the dynamic flow rate.

摘要： A fuel injection valve with a valve body (1), which has a bore (3) that contains a piston-shaped valve member (5) in a longitudinally movable fashion, which valve member (5), with its end oriented toward the combustion chamber, controls the opening of at least one injection opening (17). The valve member (5) is guided in the bore (3) with a sealing section (105) oriented away from the combustion chamber and a guiding section (205) oriented toward the combustion chamber; between the sealing section (105) and the guiding section (205), the valve member (5) is encompassed by a first pressure chamber (9) that can be filled with fuel and between the guiding section (205) and the combustion chamber end, is encompassed by a second pressure chamber (19). In the guiding section (205) of the valve member (5), an annular collar (22) is provided, which constitutes the combustion chamber end of the guiding section (205) and has a side (37) oriented toward the combustion chamber and a side (36) oriented away from the combustion chamber. During the opening stroke motion of the valve member (5), the annular collar (22) emerges from a bore guiding section (203) and thus opens or connects the first pressure chamber (9) to the second pressure chamber (19). The annular collar (22) has a throttle connection (40) embodied on it, which connects the sides (36, 37) of the annular collar (22) to each other and thus produces a throttled connection from the first pressure chamber (9) to the second pressure chamber (19) (FIG. 1).
