Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coolant pump for delivering a coolant in a coolant circuit of a combustion engine, said coolant pump comprising: a) a housing; b) a drive shaft, which is rotatably mounted by the housing, for being rotationally driven by the combustion engine; c) a radial feed wheel which can be rotationally driven by the drive shaft, for delivering the coolant from a radially internal inflow region into a radially more external outflow region; d) a setting str…
