    • A jet pump for a heat gun includes an elongate hollow pump body (36) lying along a longitudinal axis. The pump body has an inlet (37), a mixing section (40) and an outlet. A nozzle unit (26) is axially aligned with the inlet for directing pressurized fuel into the inlet of the pump body. Movement of the pressurized fuel into the inlet causes air to be drawn into the inlet to mix with the fuel within the pump body. A disk shaped air diverter (30) is axially spaced away from the inlet of the pump body. The diverter has a length and a diameter. The diameter of the diverter is greater than the length of the diverter and larger than the inlet of the pump body. A housing (33) is radially spaced from and surrounds the diverter forming a first annular gap therearound for air outside the housing to pass therethrough. The air moves around the diverter then changes direction between the diverter and the inlet of the pump body before entering the inlet.
    • 用于加热枪的喷射泵包括沿着纵向轴线放置的细长中空泵体(36)。 泵体具有入口(37),混合部分(40)和出口。 喷嘴单元(26)与入口轴向对齐,用于将加压燃料引入泵体的入口。 加压燃料进入入口使得空气被吸入入口以与泵体内的燃料混合。 盘形空气转向器(30)与泵体的入口轴向间隔开。 转向器有一个长度和一个直径。 分流器的直径大于分流器的长度并大于泵体的入口。 壳体(33)与转向器径向隔开并围绕该转向器,从而在其周围形成第一环形间隙,用于壳体外部的空气通过其中。 空气在分流器周围移动,然后在进入入口之前改变分流器和泵体入口之间的方向。

    • A fluid mixing device comprising:
          wall structure defining a chamber (6) having a fluid inlet (1) and a fluid outlet (4) disposed generally opposite the inlet;
          said chamber being larger in cross-section than said inlet at least for a portion of the space between said inlet and outlet;
          flow separation means (2) to cause a flow of a first fluid wholly occupying said inlet to separate from said wall structure upstream of the outlet;
          wherein the distance between said flow seaparation means and said outlet is sufficiently long in relation to the width of the chamber for the separated flow to reattach itself asymmetrically (22) to the chamber wall structure upstream of the outlet and to exit the chamber through the outlet asymmetrically (23), whereby a reverse flow (26) of said first fluid at said reattachment and/or a flow (24) of a second fluid induced from the exterior of the chamber through said outlet swirls in the chamber between said flow separation and said reattachment and thereby induces precession of said separated/reattached flow, which precession enhances mixing of the flow with said second fluid to the exterior of the chamber.
    • 一种流体混合装置,包括:壁结构,其限定具有流体入口(1)的腔室(6)和与入口大致相对设置的流体出口(4) 所述腔室至少对于所述入口和出口之间的空间的一部分在横截面上大于所述入口; 流动分离装置(2)使整个占据所述入口的第一流体的流动与出口上游的所述壁结构分离; 其中所述流动出水装置和所述出口之间的距离相对于用于分离流动的室的宽度足够长,以使其自身不对称地(22)重新连接到出口上游的室壁结构,并通过出口离开室 不对称地(23),由此在所述重新附接的所述第一流体的逆流(26)和/或通过所述出口从所述室的外部引起的第二流体的流(24)在所述流动分离和 所述重新附接并因此引起所述分离/重新附着的流动的进动,该进动增强了流体与所述第二流体到室的外部的混合。
