Abstract: A separating unit for a suction apparatus includes a collection container within a housing wall. A filter unit within the container retains dirt particles from suction air flowing on the filter surface. The container has an inlet opening at the wall closed by a flap having a total surface covering the opening and being fastened to the wall at a main edge. The flap has a main desired bending point on the main edge, enabling bending of the total surface about a main bending axis. The flap has a linear desired bending point enabling bending of a partial area of the total surface facing away from the main edge about an additional bending axis. The flap allows bending of the partial area away from the wall by force acting on the flap from outside, exposing a partial area of the opening corresponding to the partial area of the total surface.

Abstract: A separator unit includes a collecting container enclosed by a housing wall, extending along a longitudinal axis, and having an inlet opening disposed on the housing wall for a suction airflow. The separator unit is configured in such a manner that a suction airflow that is passing through the inlet opening into the collecting container has a flow direction running in the circumferential direction with regard to the longitudinal axis. The separator unit includes a diversion element which is positioned downstream along the flow direction and has a surface which acts on the suction airflow. The normal vector of an obliquely positioned section of the surface of the diversion element runs in an oblique manner with respect to the longitudinal axis. A suction apparatus having the separator unit is also provided.

Abstract: A separating unit for a suction apparatus includes a collecting container enclosed by a housing wall. The collecting container has an inlet opening for a suction air flow disposed on the housing wall, which is covered with a flexible flap. The flexible flap is fastened to the housing wall at a leading edge of the flap and has a first portion and a subsequent second portion along the leading edge. The flap is configured to be bent into the collecting container away from the housing wall by an external force acting on the flap and as a result exposes the inlet opening at least in part. The separating unit is configured such that the bending away of the first portion of the flap is more greatly restricted than the bending away of the second portion of the flap. A suction apparatus having the separating unit is also provided.

Abstract: A separating unit for a suction apparatus includes a collecting container surrounded by a housing wall extending along a longitudinal axis and having an inlet opening for a suction air flow. The separating unit causes the suction air flow entering through the inlet opening into the collecting container to have a flow direction in a circumferential direction relative to the longitudinal axis. An annular diversion element has a surface acting on the suction air flow entering into the collecting container. The surface of the diversion element, at least partially, runs helically along the inside of the housing wall around the longitudinal axis. The surface of the diversion element has a step with first and second edges mutually spaced apart along the longitudinal axis. The step of the surface runs at an angle relative to the longitudinal axis. A suction apparatus having the separating unit is also provided.

Abstract: A separating unit for a suction apparatus includes a collecting container for particles of dirt, which is surrounded by a housing wall. The collecting container extends along a longitudinal axis. The separating unit also includes an ejection and/or a compacting element which is configured to be moved inside the collecting container, starting from an initial position along the longitudinal axis to a compacting position in order to compact particles of dirt disposed in the collecting container and/or to eject them from the collecting container. The separating unit is configured in such a way that a radial force, with which the ejection and/or compacting element acts in the radial direction on the inside of the housing wall, is lower at the compacting position than at the initial position. A suction apparatus having the separating unit is also provided.

Abstract: A separator unit for a suction apparatus contains a collection container with a collection area for receiving particles of dirt from a suction airflow. The collection container runs along a longitudinal axis from a first end side, which during the operation of the suction apparatus faces the blower of the suction apparatus, up to a second end side on which the cover of the collection container is arranged. The separator unit contains a filter module arranged in the collection container and is configured to filter particles of dirt out of the suction airflow. The collection area is adjacent to the surface of the filter module and the filter module is configured so as on the first end side of the collection container to be removed from the collection container or to be inserted into the collection container.

Abstract: A damping arrangement for dampening rotational irregularities in a drive train of a motor vehicle, having a slip arrangement providing slip between an input and output region of a torque-transmitting arrangement. The slip arrangement has a closed-loop control device that performs closed-loop control of the slip dependent on a measured signal for a rotational irregularity. The closed-loop control device performs closed-loop control of the slip dependent on at least one characteristic variable of a periodic oscillation component of an alternating component of a rotational speed proceeding from an average rotational speed. A sensor device is connected to the closed-loop control device and is designed to ascertain the average rotational speed in the torque-transmitting path downstream of the slip arrangement and to ascertain a frequency of the alternating component in the torque-transmitting path upstream of the slip arrangement.
