摘要

The device has pumping units (16a, 16b), which are operated parallely during a supply operation. A part of the pump units is formed with variable supply capacity for influencing the volumetric flow of a fluid to be supplied. The pump units are selectively activated and deactivated. A control device (22) controls the supply of the fluid to the activated pump units by a clocked control signal.
