  • Publication number: 20240003364
    Abstract: A pivot actuator (1), comprising: a housing (2); a piston (3) that is supported in the housing (2) and displaceable along a longitudinal axis (7) of the housing; a drive shaft (4) that protrudes from the housing (2) wherein the piston (3) engages the drive shaft (4) by form locking so that the drive shaft (4) is pivoted about a drive axis (8) by a pivot angle (10) to an end position through a displacement of the piston; and a switching cam (11, 26) that is fixed torque proof at the drive shaft (4) and configured to contact a stop element (5) at the housing (2) with a convex stop surface (18) at the switch element, wherein the end position is adjustable by an adjustment angle (25) about the drive axis (8) by displacing the stop element (5) along an adjustment axis (20) transversal to the drive axis (8), characterized in that the stop surface (18) follows an involute (22) of a circle (23) about the drive axis (8) wherein the involute is arranged in a direction transversal to the drive axis (8) so that the circl

  • Publication number: 20240003365
    Abstract: The invention relates to a pivot actuator (1), comprising: a housing (2); a piston (3) that is supported in the housing (2) and displaceable along a longitudinal axis (7) of the housing; a drive shalt (4) that protrudes from the housing (2) wherein the piston (3) engages the drive shaft (4) by form locking so that the drive shaft (4) is pivoted about a drive axis (8) by a pivot angle between two end positions through a displacement of the piston; and a switching cam (11) that is fixed torque proof at the drive shaft and configured to contact a stop element (5) at the housing (2) with a respective contact surface (ill) of the switch cam in the two end positions, characterized in that the switching cam (11) includes two discs (15) that are arranged adjacent to one another along the drive axis (8), wherein one respective contact surface (18) of the two contact surfaces (18) is arranged at each of the two discs (15) respectively.

  • Patent number: 8401623
    Abstract: The invention proposes a detection chamber (5) comprising a fluid-tight measurement volume (20) the size of which can be varied using a movable wall portion (15). Such a detection chamber (5) allows compression of the object to be imaged as well as the use of a matching medium to fill the space inside the measurement volume (20) not filled by the object to be imaged.
