Abstract (en)
[origin: EP2392828A2] The pump (1) has a hollow shaft (3) placed in a pump housing (2) and connecting a drive wheel to an impeller (4). Coolant is drawn in via a cover disk (8), which is provided upstream to a suction chamber (5), by rotating the impeller. An axially displaceable baffle plate (9) attached to the impeller influences delivery volume. The plate is connected to a push rod (10) guided into the shaft in a torsionally rigid manner. The plate acts together with an adjusting unit i.e. electromagnet. A sealing element (14) seals an annular gap (13) formed between the plate and the disk. The sealing element is made of elastomer.
