Abstract: A low pressure blower operated airknife having a housing with an elongated primary air discharge orifice for directing a narrow width curtain of air. The airknife includes an air-augmenting shroud which defines auxiliary discharge orifices on opposite longitudinal sides of the primary air discharge orifice such that air discharging from the primary discharge orifice creates a low pressure condition adjacent the auxiliary air discharge orifices for drawing additional air through the auxiliary discharge orifices which augments the velocity and volume of the discharging air current without the necessity for increasing the air inlet pressure or blower size. The shroud may take alternative forms, including pairs of wings disposed on opposite sides of the primary discharge orifice or hollow structures that surround the airknife housing. The airknife further is adapted for low pressure direction and application of air laden particles, such as preatomized liquid particles.

Abstract translation: 一种低压鼓风机操作的气刀，其具有带有细长一次空气排放孔的壳体，用于引导狭窄的宽度的空气帘。 气刀包括一个空气增强罩，其在主空气排放孔的相对的纵向侧面上限定辅助排放孔，使得从主排放孔排出的空气在辅助空气排出孔附近产生低压状态，用于通过辅助空气抽吸附加空气 排放孔，其不需要增加空气入口压力或鼓风机尺寸，这增加了排放气流的速度和体积。 护罩可以采取替代形式，包括设置在主排放口的相对侧上的一对翼或围绕气刀壳的中空结构。 气刀进一步适用于低压方向和应用含空气的颗粒，例如预先溶解的液体颗粒。
