Homogeneous fluid composition by controlling a primary piston of a piston pump system

Fluid supply system (150) for providing a fluid to a fluid sink (30), wherein the fluid supply system (150) comprises a feed device (25) for supplying a plurality of fluidic components (A to D) composite fluid, a primary piston pump (111) by means of the feed device (25) is to be pumped fluid fed and a means for conveying the fluid in a primary piston chamber (117) reziprozierfahig arranged primary piston (115), and control means (70) for controlling the primary piston (115) such that arranged independently of a downstream of the primary piston (115) fluidic component (118) (a to D) is a Ansaugcharakteristik of the primary piston (115) depending on the composition of the fluid from the plurality of fluidic components be adjusted such that the fluid collector ( 30) a homogeneous composite within a respective time window, fluid is provided.
