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 turbocharger includes a waste gate valve, a compressor, a turbine, a turbine housing which houses the turbine, a bypass channel which bypasses the turbine, a bypass channel section arranged in the turbine housing, an actuator housing which has a separate coolant channel, an electric motor arranged in the actuator housing, a transmission which has an output shaft, a control body coupled to the output shaft, and an actuator cover. The transmission is arranged in the actuator housing. The actuator housing is detachably secured to the turbine housing. The control body controls an opening cross-section of the bypass channel. The separate coolant channel of the actuator housing surrounds a circumference of the transmission and is closed axially by the actuator cover.

摘要： A magnet pump for an auxiliary unit of a vehicle includes an inlet, an outlet, an electromagnet comprising an armature, a core, a coil and a yoke, a cylinder comprising an outlet opening, and an axial piston which moves in the cylinder. The axial piston includes first and second axial piston parts, a gap arranged between the first and second axial piston parts, and an axial through bore. A first non-return valve is biased between the first and second axial piston parts and against the axial piston. A second non-return valve is biased against the outlet opening of the cylinder. The first axial piston part is connected with/is integrally formed with the armature and is lifted off the second axial piston part. A fluidic connection exists between the inlet and the outlet via the gap when the first axial piston part is lifted off the second axial piston part.
