Abstract
The system has a bypass-valve/transducer limiting maximum pressure of an electrical pump, and a pressure switch (10) determining pressure in a pressure outlet. The switch controls a pump motor such that switching of the motor takes place within a maximum pressure of the pump. A pulse sensor (12) works together with the outlet to determine the flow of fluids e.g. oil, via the outlet. The pump motor is controlled such that the pump motor is switched off during high/low pressure and no flow of fluid though the outlet and is switched on during high/low pressure and flow through the outlet.
