| 摘要 | A pumping system includes a probe to suction a fluid from a fluid reservoir, a pump in fluid communication with the probe, and a sensor for detecting phase changes in said pumping system. The sensor is in fluid communication with the probe or pump and is operable to generate a sensor signal. The pumping system also includes a fluid exit from the pumping system that is in fluid communication with said pump, and a variable force check valve that is located between the probe and fluid exit. | ||

| 主权项 | 1. A pumping system comprising: a probe to suction a fluid from a fluid reservoir; a pump in fluid communication with the probe; a sensor to detect phase changes in the pumping system, the sensor in fluid communication with the probe or the pump, the sensor generating a sensor signal; a fluid exit from the pumping system, the fluid exit being in fluid communication with they pump; and a variable force check valve having a controllable force adjustment mechanism and being located between the probe and the fluid exit. | ||
