    Abstract: The present invention is directed to a check valve 10, an injection assembly 60, and a beverage preparation machine 100, which is integrated in the injection assembly 60. The check valve 10 of the present invention is made of a body with a first fluid outlet 21, and a plug member 30 that is movable inside the body 20. The plug member 30 has a fluid inlet 32 and a second fluid outlet 31 into a first cavity 11, wherein the fluid can exercise a pressure on a first surface 381 of the plug member 30 opposing the first fluid outlet 21. The fluid pressure can overcome the force of an elastic element 40, which biases the plug member 30 into a closed position. If the force of the elastic member 40 is overcome, the plug member 30 is moved into an open position. In the closed position a fluid path from the cavity 11 out of the first fluid outlet 21 is closed, whereas in the open position said fluid path is open. To move the plug member 30 from its initial closed position to its open position, a fluid pressure on the first surface has to be equal to or larger than a predetermined threshold.

    Abstract translation: 本发明涉及集成在注射组件60中的止回阀10,注射组件60和饮料制备机器100.本发明的止回阀10由具有第一流体出口 插塞构件30具有流体入口32和第二流体出口31,该流体入口32和第二流体出口31进入第一空腔11,其中流体可以在第一空腔11的第一表面381上施加压力 插塞构件30与第一流体出口21相对。流体压力可克服弹性元件40的力,弹性元件40将插塞构件30偏压到闭合位置。 如果弹性构件40的力被克服,则塞构件30移动到打开位置。 在关闭位置,从第一流体出口21离开空腔11的流体路径是关闭的,而在打开位置,所述流体路径是敞开的。 为了将插头构件30从其初始关闭位置移动到其打开位置,第一表面上的流体压力必须等于或大于预定阈值。
