| 摘要 |
The mechanically governed fuel injection pumping element disclosed is embodied with a piston (16) in two stages (1, 2), and a barrel (15) incorporating a gallery (7) which interconnects two pressure chambers (3, 4) to the end of producing a dual injection when the assembly is reciprocated by a common drive component (17), thereby providing a more gradual rate of injection. In a preferred embodiment, the two stages (1, 2) are proportioned such as to dictate the quantity ratio between the two injections, and the interval of time separating them.
