Abstract

See full text

A coolant pump for delivering a coolant in a coolant circuit of a combustion engine, including: a housing; a drive shaft, rotatably mounted by the housing and rotationally driven by the combustion engine; a radial feed wheel, rotationally driven by the drive shaft, for delivering coolant from a radially internal inflow region into a radially more external outflow region; a setting structure, adjustable into different positions relative to the housing by control fluid, for adjusting a flow geometry which influences the delivery volume of the pump at a given rotational speed; a control valve for setting a pressure or volume flow of the control fluid which determines the position of the setting structure; and a servo pump, which is a rotary pump including at least one servo pump wheel and can be rotationally driven by the drive shaft, for delivering the control fluid to the control valve.
