Abstract (en)
[origin: WO2015062752A1] The invention relates to a coolant pump for use in the automotive field for delivering a coolant volumetric flow with a housing (4), in which a pump shaft (10) is rotatably mounted with a rotor (18) which is arranged fixedly thereon so as to rotate with it, wherein a regulating device (22) for regulating the volumetric flow is provided, which regulating device (22) has a slide element (24) which can be displaced into an outflow region (16) of the rotor (18) and can be driven via a hydraulic control device (26), wherein the hydraulic control device (26) has a radial piston pump (28), an actuating device (30), a control duct arrangement (32) and at least one piston device (34) which can be connected fluidically to one another in such a way that the slide element (24) can be actuated by way of the piston device (34), wherein the actuating device (30) has a valve arrangement which is operatively connected to the control duct arrangement (32), consisting of an electromagnetic valve (26) and at least one check valve (48, 50, 52).
