Abstract (en)
[origin: WO2017076644A1] The invention relates to control arrangements for mechanically controllable coolant pumps comprising an adjustable control slide (56), by means of which a through-flow cross-section of an annular gap (60) between an outlet (62) of a coolant pump impeller (20) and a surrounding conveying channel (12) can be controlled, a control pump (36), by means of which a hydraulic pressure can be generated in a flow channel (42), a first pressure chamber (72) of the control slide (56) which is formed on a first axial side of the control slide (56), a solenoid valve (78) having two valve seats (110, 112), three flow connections (118, 120, 122), and a closing member (76) which is connected to an armature (96) of the solenoid valve (76) and is axially movable, wherein the first flow connection (118) is fluidically connected to an outlet (46) of the control pump (36) and the second flow connection (120) is fluidically connected to the first pressure chamber (72) of the control slide (56). In order to be able to design such a control arrangement for the fastest possible control, according to the invention the third flow connection (122) is connected fluidically to an inlet (14) of the coolant pump (11), wherein the first valve seat (110) is formed between the first flow connection (118) and the second flow connection (120) and the second valve seat (112) is formed between the second flow connection (120) and the third flow connection (122).
