  • Patent number: 12158212
    Abstract: A hydraulic valve device includes a first inlet port (20) and a second inlet port (22) and a valve element (24) for selectively closing one of the first and the second inlet port. The valve element (24; 24?) is rotatable between two valve positions such that a surface of the valve element is moved in a direction parallel to openings of the inlet ports. The valve element includes two separate sealing portions (72, 74), a first sealing portion (72) for closing the first inlet port and a second sealing portion (74) for closing the second inlet port. The two sealing portions are arranged such that in a first valve position a first sealing portion closes the first inlet port and in a second valve position a second sealing portion closes the second inlet port. A centrifugal pump device includes such hydraulic valve device.

  • Patent number: 11680571
    Abstract: A centrifugal pump assembly includes an electric drive motor (6, 8), a driven impeller (14) and a pump casing (2) which surrounds the impeller (14). A movable element (24; 24?) is arranged a valve element. A section of the valve element is movable from a released position into a bearing position, fixed on a contact surface (60), by pressure which is produced by the impeller in the pump casing. A control device (64) moves the valve element from one switching position into another switching position and reduces the speed of the drive motor. Upon pressure in the pump casing dropping such that the valve element is no longer fixed on the contact surface and the valve element has been moved into the other switching position, the control device increases the speed of the drive motor again. A method for moving a valve element is provided.
