摘要： The present invention is directed to a controllable mechanical motor vehicle coolant pump (10) with a coolant pump wheel (16) which is co-rotatably connected with a drive shaft (12), a transverse housing surface (28), a cylindrical inner slider support surface (32) which is coaxial to the drive shaft (12), a control slider (22) which is axially shiftable with respect to the coolant pump wheel (16) in order to control an effective discharge flow cross-section (D-eff) of the coolant pump wheel (16), the control slider (22) comprising a substantially cylindrical slider side wall (24) and a slider bottom wall (26) which is arranged axially between the coolant pump wheel (16) and the transverse housing surface (28), wherein a radially inner bottom wall surface (30) of the slider bottom wall (26) is shiftably supported by the inner slider support surface (32), and a push-out pressure chamber (40) which is located between the slider bottom wall (26) and the transverse housing surface (28), is defined at one axial side by the transverse housing surface (28) and radially inwardly by the inner slider support surface (32), and is configured to be hydraulically pressurized in order to generate a hydraulic push-out push force which pushes the slider bottom wall (26) toward the coolant pump wheel (16). According to the present invention, the transverse housing surface (28) and the inner slider support surface (32) are both defined by a first housing element (14) so that fluid leakage into the push-out pressure chamber (40) can be avoided or at least significantly reduced. This allows reliable control of a shifting position of the control slider (22) and thus of a coolant discharge flow of the coolant pump wheel (16).

摘要： A coolant pump for providing a coolant to an engine includes a pump frame, a rotatable rotor shaft, a pulley wheel co-rotatably fixed to the rotor shaft, an axially shiftable ferromagnetic rotatable pump wheel, and an electromagnetic wet friction clutch arrangement. The pump wheel is axially shiftable with respect to the rotor shaft and the pump frame. The clutch arrangement comprises a static electromagnet, a clutch disk co-rotatably supported by the rotor shaft, a first clutch friction surface arranged at the clutch disk and a thereto corresponding second clutch friction surface arranged at the pump wheel, and a separate stop friction surface arranged at the pump wheel and a thereto corresponding static stop friction surface arranged at the static pump frame. The electromagnet, when fully energized, axially attracts the pump wheel so that the separate stop friction surface and the static stop friction surface engage to stop the pump wheel.
