摘要：
Variable flow rate fuel ejectors, and methods of use therefore, are disclosed. One variable flow rate ejector includes a primary nozzle, a needle, a motor, a first stop portion, and a first impact-absorbing portion. The primary nozzle is connected to a first inlet chamber to receive a first fluid and transmit a flow of the first fluid through the primary nozzle opening. The needle is disposed to create a gap between the tapered portion of the needle and the primary nozzle opening. The motor is coupled to axially move the needle to vary a size of the gap. The first stop portion delimits the axial movement of the needle in a direction of retraction of the needle from the primary nozzle opening. The first impact-absorbing element is positioned to contact the first stop portion or the needle, respectively, when the needle is fully retracted from the primary nozzle opening.
摘要（中）：
可变流量燃料喷射器以及因此使用的方法被公开。 一个可变流量喷射器包括主喷嘴，针，马达，第一止挡部分和第一冲击吸收部分。 主喷嘴连接到第一入口室以接收第一流体并且透过第一流体通过主喷嘴开口的流动。 针被设置成在针的锥形部分和主喷嘴开口之间产生间隙。 马达被联接以轴向移动针来改变间隙的尺寸。 第一止挡部分限定针沿着针头从主喷嘴开口缩回的方向的轴向运动。 当针从主喷嘴开口完全缩回时，第一冲击吸收元件分别定位成与第一止挡部分或针接触。
