摘要： A controllable coolant pump driven by a belt pulley for internal combustion engines is equipped with a valve slide. A seal is disposed on the outer edge of the wall plate between the plate and the outer cylinder of the valve slide. At least one additional flow outlet opening is disposed on the pump housing, the outlet volume stream of which openings can be additionally controlled, aside from the controllable volume stream that exits from the flow exit opening. The flow outlet opening from which the controllable outlet volume stream exits is connected with an outflow opening disposed near the rear wall of the valve slide, in the pump chamber rear wall, via an outflow channel. The outflow opening is enclosed by a ring seal disposed in the pump chamber rear wall, which enters into operative engagement with the valve slide in its rear end position.

摘要： The present invention proposes a coolant pump for a coolant circuit of the internal combustion engine of a motor vehicle including at least a radiator circuit and a bypass circuit. The coolant pump comprises 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) 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). It is proposed for the first time to arrange the intake pipe (22) in the area of the end of the pump motor facing away from the pump impeller (32). Furthermore the bypass pipe is to be arranged in an area downstream of the intake pipe (22). Moreover the pressure pipe (34) is to be arranged in an area downstream of the bypass pipe (24). Finally only the coolant that can be taken in by the radiator via the intake pipe is to be 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). The present invention also specifies a corresponding method.
