摘要： A coolant pump includes a pump frame, a driving wheel driven by an engine, a pump wheel driven by the driving wheel, and a clutch which couples the driving wheel with the pump wheel. The clutch comprises a friction surface arranged at the driving wheel, and a clutch disc which corresponds to the friction surface. The clutch disk is connected with and co-rotates with the pump wheel, and is axially shiftable between an engaged and a disengaged position. An axial pretension spring pretensions the clutch disc into the disengaged position. A permanent magnet forces the clutch disc into the engaged position. An electromagnet, when energized, generates a polarization which is opposite to a polarization of the permanent magnet to reduce a total magnetic attraction force of the permanent magnet with respect to the clutch disc and to thereby push the clutch disc into the disengaged position via the pretension spring.

摘要： A mechanical coolant pump for an internal combustion engine includes an impeller pump wheel. The pump housing comprises an outlet valve arrangement arranged between an outlet volute and a pump outlet, and a support portion. The pump housing closes and/or opens a valve opening. The outlet valve arrangement comprises a valve body which pivots. The valve body comprises a closing element which covers the valve opening, and first and second end disks. The closing element comprises an opening seat in a closed valve position. The first and second end disks are parallel to each other, are arranged at opposite axial ends of, and perpendicular to, the closing element, and rotate around a pivot axis. The first and second end disks each comprise a radial clamping nose which acts with the support portion to radially push the closing element against the opening seat in a closed valve position.
