Abstract

A coolant pump and method thereof for a coolant circuit of the internal combustion engine of a motor vehicle including at least a radiator circuit and a bypass circuit is disclosed. The coolant pump contains a coolant pump housing ( 14 ) which is provided with an intake pipe ( 22 ), a bypass pipe ( 24 ), and a pressure pipe ( 34 ). A coolant pump electric motor ( 26 ) is arranged in the coolant pump housing ( 14 ), the motor housing ( 28 ) of which is situated in the coolant flow, drives a pump impeller ( 32 ) via a pump shaft ( 30 ). A directional control valve ( 40 ) is integrated into the coolant pump housing ( 14 ). The intake pipe ( 22 ) is arranged in the area of the end of the pump motor facing away from the pump impeller ( 32 ). Furthermore the bypass pipe is arranged in an area downstream of the intake pipe ( 22 ).The pressure pipe ( 34 ) is arranged in an area downstream of the bypass pipe ( 24 ). Only the coolant that can be taken in by the radiator via the intake pipe is adapted to be guided past the pump motor in a peripheral flow ( 50 ) in particular through a flow channel ( 56 ) limited by the outer wall ( 52 ) of the pump motor housing ( 28 ) and the facing inner wall ( 54 ) of the pump housing and/or the facing inner wall ( 60 ) of the directional control valve ( 40 ).
