摘要： A control arrangement for a coolant pump of an internal combustion engine includes a control slide which controls a throughflow cross-section of an annular gap arranged between an outlet of a coolant pump impeller and a surrounding delivery duct. A control pump adapts a hydraulic pressure generated in a flow duct. An electromagnetic valve includes a first and second valve seat, a first, second and third flow connection, a closing member and an armature. The first flow connection is fluidically connected to an outlet of the control pump. The second flow connection is fluidically connected to a first pressure chamber of the control slide. The third flow connection is fluidically connected to an inlet of the coolant pump. The first valve seat is arranged between the first flow connection and the second flow connection. The second valve seat is arranged between the second flow connection and the third flow connection.

摘要： A coolant pump for an internal combustion engine. The coolant pump includes a delivery duct, a drive shaft, a coolant pump impeller arranged on the drive shaft to rotate therewith and to convey a coolant, and an adjustable control slide which controls a throughflow cross-section of an annular gap arranged between an outlet of the coolant pump impeller and the surrounding delivery duct. The control slide comprises a first pressure chamber arranged on a side of the control slide facing away from the coolant pump impeller and a second pressure chamber arranged opposite thereto. A control pump includes a control pump impeller arranged at the drive shaft to rotate therewith. A connecting duct fluidically connects the flow duct to the second pressure chamber. A pressure duct fluidically connects the flow duct outlet to the first pressure chamber. A valve opens and closes a throughflow cross-section of the pressure duct.

摘要： A device for an anode gas recirculation in a fuel cell system includes a blower attached to an interface unit. The blower has a blower inlet and outlet, a conveying channel with an inlet and outlet, and a cooling channel partially surrounding an electric motor which extends from an inlet to an outlet. The interface unit has a first anode gas channel extending from a first inlet fluidically connected to a fuel cell outlet to a first outlet connected to the blower's inlet, and a second anode gas channel extending from a second inlet connected to the blower's outlet to a second outlet fluidically connected to a fuel cell inlet. The cooling channel is connected via its inlet to the first outlet or to a third outlet of the interface unit, and/or is connected via its outlet to a third inlet or to the second inlet of the interface unit.

摘要： A method for controlling a coolant pump for an engine includes delivering a coolant via a coolant pump impeller into a delivery duct to a pump outlet, and adjusting the delivery based on a position of an adjustable control slide which controls a throughflow cross-section of an annular gap between the coolant pump impeller outlet and the delivery duct. A first pressure chamber on a side of the control slide is filled with a pressurized coolant to decrease the throughflow cross-section and the coolant volume flow delivered to the pump outlet, or a second pressure space arranged on an opposite side is filled with the pressurized coolant to increase the throughflow cross-section and the coolant volume flow delivered to the pump outlet. The control slide is moved into a defined position when the engine is switched off dependent on a coolant temperature and remains in that position until a restart.

摘要： A stator includes a stator stack comprising stator poles, a groove arranged between each of the stator poles, and a coil winding comprising a winding end arranged on each of the stator poles. The winding ends comprise cophasal coil windings and non-cophasal coil windings. A guiding body comprises an axial surface arranged opposite to the stator stack, a wall extending perpendicular to a central axis of the stator stack, and guiding body contours. Connecting bodies connect the cophasal coil windings with each other. Each of the connecting bodies comprises a connecting body contour. The connecting body contours engage with the corresponding guiding body contours. Isolating bodies electrically isolate the non-cophasal coil windings from each other. The winding ends extend at a common axial end of the stator beyond the stator stack into the guiding body.
