| 摘要 | A valve includes an interior portion and a nozzle passage. The valve further includes a poppet having a first stage portion and a second stage portion. The poppet has a closed position in which the first stage portion and the second stage portion seal the interior portion of the valve from the nozzle passage. The poppet also has a partially open position, in which the first stage portion of the poppet is spaced from the second stage portion of the poppet, and defines a first fluid passage between the interior portion of the valve and the nozzle passage. Additionally, the poppet has a fully open position, in which the second stage portion of the poppet is spaced from the nozzle passage of the valve, and defines a second fluid passage between the interior portion of the valve and the nozzle passage. | ||
