  • Patent number: 12025232
    Abstract: A valve has a housing that delimits an interior, a first connection, a second connection, a passage that fluidically connects the first and second connections, first and second closing elements received in the interior and surrounding an intermediate space connected to a third connection, and an adjustment device that, in a closed position, brings the first closing element into sealing contact with a first valve seat formed in the passage and the second closing element into sealing contact with a second valve seat formed in the passage. The first closing element is sealingly received in the second closing element.

  • Patent number: 10634145
    Abstract: A self-priming pump assembly comprises a series connection of a liquid ring pump functioning as a rotating displacement pump and a normally-priming centrifugal pump. The self-priming pump assembly improves the fluid mechanics conditions for the flow of fluids toward and into a return line through the inclusion of a first connection opening in the meridian plane of the centrifugal pump that possesses a bulge enclosing a sector of the longitudinal axis of the first connection opening, where the bulge is one-sided and oriented toward a rotary axis of the pump assembly, and the bulge continuously expands, directly or indirectly, the first connection opening toward the impeller plane. At its end section facing the impeller plane, a transitional surface of the bulge continuously transitions into the lateral boundary surface, or an inner peripheral wall of the ring channel adjoining the lateral boundary surface.
