  • Patent number: 11091189
    Abstract: A steering shaft for a vehicle includes a hollow outer shaft arranged telescopically and coaxially about an inner shaft and connected in a torque-transmitting manner via at least one rolling body. The rolling body bears against the inner shaft and the outer shaft in a positively locking manner in the circumferential direction with regard to a rotation about the longitudinal axis. The steering shaft includes a securing element fixed on the outer shaft and a torque-transmitting coupling section via which the inner shaft and the outer shaft are connected. For an improved redundant transmission of torque in the case of the failure of rolling bodies, the coupling section has at least one transmission body which engages in a loose positively locking connection with regard to a rotation about the longitudinal axis between the rolling body raceways of the inner shaft and the outer shaft.

  • Patent number: 9119911
    Abstract: A dosing unit for an ambulatory infusion device and a method of operation are disclosed. The dosing unit includes a stationary member, a movable member, and a plunger. The movable member and the stationary member, together, make a charging valve and a discharging valve. The plunger is located, at least in part, in a metering cavity of the movable member and the movable member is adapted to selectively couple and decouple a driving unit, such that, by operating the driving unit with the movable member being coupled with the driving unit, the movable member moves with the plunger to maintain a position of the plunger relative to the movable member along a displacement axis, and by operating the driving unit with the movable member being decoupled from the driving unit, the plunger is displaced while the position of the movable member is maintained.
