    • A firefighting vehicle having a dual pressure pump system includes a fluid supply, a first pump stage coupled to the fluid supply and configured to pump fluid at a first pressure, a second pump stage coupled to the first pump stage and configured to pump fluid at a second pressure, the second pressure being substantially different from the first pressure, a fluid manipulator; and a valving arrangement coupling the first pump stage and the second pump stage to the fluid manipulator, the valving arrangement being selectively adjustable between a first position forming a first fluid path and a second position forming a second fluid path, wherein the first fluid path provides the fluid to the fluid manipulator at a first output pressure and the second fluid path provides fluid to the fluid manipulator at a second output pressure.
    • 具有双重压力泵系统的消防车辆包括流体供应,联接到流体供应并被配置成在第一压力下泵送流体的第一泵级,耦合到第一泵级的第二泵级,并且构造成在 第二压力,第二压力基本上不同于第一压力,流体操纵器; 以及将所述第一泵级和所述第二泵级耦合到所述流体操纵器的阀装置,所述阀装置可选择性地在形成第一流体路径的第一位置和形成第二流体路径的第二位置之间调节,其中所述第一流体路径提供 在第一输出压力下以流体机械手的流体和第二流体路径在第二输出压力下向流体操纵器提供流体。
