  • Pump Assembly With Safety Valve
    Publication number: 20080188810
    Abstract: The invention provides a pump assembly comprising a suction pump and a safety valve arranged between the pump inlet and a fluid inlet for the assembly. The safety valve comprises an inlet valve and a moveable control member acting on the safety inlet valve, wherein the control member is operatable between an initial position in which the safety inlet valve is closed, and an activated position in which the safety inlet valve is open, and wherein the control member is moved from the initial to the activated position by means of suction action from the pump. By this arrangement the opening of the safety valve is positively controlled by the suction provided by the pump whereas the safety valve is closed during non-operation of the pump.
