METHOD OF OPERATING A FLUID WORKING MACHINE

摘要

When the fluid flow output of a synthetically commutated hydraulic pump is adapted to a given fluid flow demand, pulsations in the fluid output flow of the synthetically commutated hydraulic pump can occur. To avoid such pressure pulsations, it is suggested, to use a set of pre- calculated actuation patterns for actuating the electrically commutated valves of the synthetically commutated hydraulic pump.
