  • Patent number: 11285410
    Abstract: A filtration system (1) has a filtration unit (2) with at least one filter element (4) for filtration of a fluid. The at least one filter element (4) has a main flow direction (C) for the fluid. The filtration unit (2) is configured to tilt the at least one filter element (4) around a tilting axis (B) to change an orientation of the main flow direction (C). A main unit (3) is fluidly connectable to the filtration unit (2) and includes a supply unit (18) configured to supply the fluid to the at least one filter element (4). A control unit is configured to control supplying and/or evacuating the fluid to/from the at least one filter element (4) and to control tilting of the at least one filter element (4) around the tilting axis (B).
    Type: Grant

  • Patent number: 9400059
    Abstract: A tube constriction valve has a valve body (1) with an approximation sensor (3) and a clamping bolt (2) that squeezes the tube inside the valve body (1). The approximation sensor (3) detects the position of the tube constriction valve and can indicate corresponding data by an approximation element (4) on the clamping bolt (2). The tube constriction valve allows for automatic and also manual operation and at the same time contains a position indicator. Consequently, damage to the tube is prevented and processing reliability preserved.
