The present invention provides an adjustment arrangement (), comprising a rotating input element () at which a first torque from a motor arrangement () can be inputted into the adjustment arrangement, a rotating output element () at which a second torque can be outputted by the adjustment arrangement, and a transmission portion for converting the first torque into the second torque, the transmission portion comprising a transmission means () having a first threaded portion () and a second threaded portion (), the first threaded portion converting a rotation of the input element () into an axial movement of the transmission means, and the second threaded portion converting an axial movement of the transmission means into a rotation of the output element ().

Adjustment arrangement and valve control device comprising an adjustment arrangement

The present invention relates to a drive arrangement, comprising a motor drive shaft, which makes the drive force of a motor available, an output shaft, via which the drive arrangement outputs and accumulates a rotational force, a coupling, which is designed to transmit a rotational force from the motor drive shaft to the output shaft and from the output shaft to the motor drive shaft, and a braking arrangement, which counteracts a rotational movement of the output shaft with a braking force.

Drive arrangement and hatch control

A drive device includes a drive device housing with a longitudinal axis, at least one gearing assembly received in the drive device housing, with a gearing housing, which is received in the drive device housing so as to be rotatable about the longitudinal axis thereof, an engagement element received in the drive device housing and connected thereto for rotation therewith with respect to a rotation about the longitudinal axis thereof when torque is transmitted through the engagement element, the engagement element including an end face running substantially orthogonally to the longitudinal axis, which end face is in frictional and, if desired, additionally interlocking engagement with an associated counter end face of the gearing assembly or one of the plurality of gearing assemblies, and a spring, which is received in the drive device housing and prestresses the end face and the counter end face against one another.

Drive device with overload protection

A modular system of driving devices that each includes a rotary drive assembly and a spindle drive assembly. The modular system includes at least two rotary drive assemblies and at least two spindle drive assemblies which are formed with coupling elements which are compatible with one another. The rotary drive of the driving device is received in a housing tube which is closed at its end remote from the spindle drive by a base piece. The base piece and the housing tube are manufactured from plastics material and are connected to one another by cohesive bonding.

Driving device and modular system for such a driving device

A support column with a vertical tube has a coaxially installed gas spring including a cylinder divided by a piston into first and second working chambers. A piston rod passes through the second working chamber in a sealed manner to the outside, where it is attached to a bottom support piece of the vertical tube. The cylinder projects out of the vertical tube and is guided with freedom to slide back and forth in a guide sleeve installed in the end of the vertical tube opposite the bottom support piece. A connection between the first and second working chambers can be blocked by a manually actuatable valve. A second valve between the chambers, which is closed when the gas spring is under load, can be switched to the open position after the load on the gas spring has been absent for a certain period of time.

Object-support column

An arrangement with a height-adjustable component includes an approximately vertically extending upright which bears the component, the upright including a pneumatic spring. The pneumatic spring has a cylinder having a bottom end connected to a fixed part of the arrangement. A piston displaceably arranged in the cylinder subdivides the cylinder into a bottom cylinder chamber and a top cylinder chamber and has a piston rod at one end. The piston rod projects through the top cylinder chamber and is guided out of the top end of the cylinder and bears the component at its free end. The top and bottom cylinder chambers are filled with a gas filling, under positive pressure, which subjects the piston to an upwardly directed push-out force corresponding approximately to the opposing weight-induced force of the component. A valve allows a gas flow from the top into the bottom cylinder chamber and blocks the same in the opposite flow direction. A manually actuable connecting valve selectively connects the bottom and the top chambers.

Arrangement with a height-adjustable component

A piston rod is guided in an axially movable manner within a cylinder filled with a damping medium, and a piston is arranged on the piston rod, which piston divides the cylinder into a working space on the piston-rod side and a working space remote from the piston rod. The two working spaces are connected to each other by at least one flow passage which is activated as a function of the axial position of a valve body, which is prestressed in the opening direction by a spring, the valve body being movable onto a valve seat surface into the closed position as a function of dynamic pressure and at least reducing the passage cross section of the at least one flow passage. The piston has a valve seat surface on which the valve body comes to bear with a conical closing surface in the maximally closed position.
