摘要：
A pump system that includes a pump, an injector and a regulator with a calculation unit. The regulator controls the pump to pump a liquid through a hose to the injector which opens and closes in response to an injector control signal, the time for an opening and closing cycle being called injector cycle and designated Ts, and the injector's open period being designated γ. The injector has a pressure sensor to measure the pressure of the liquid in the injector and to deliver to the calculation unit a pressure sensor signal representing the pressure amplitude in the injector. The calculation unit calculates the hose's rigidity B as a function of measured pressured amplitudes A in the injector, the injector cycle Ts and the injector's open period γ, and the regulator determines the basis of B the control signal to the pump.
