A supporting rod assembly applied to a special-shaped side door of a vehicle comprises: a master drive supporting rod comprising a master housing, a master outer guide pipe, a master end cover and a drive assembly, wherein the master outer guide pipe is movably connected to the master housing, the end of the master outer guide pipe facing away from the master housing is fixedly connected to the master end cover, and the drive assembly is arranged in the master housing and is in transmission fit with the master end cover; and a driven supporting rod comprising a slave housing, a slave outer guide pipe, a slave end cover and a slave elastic assembly, wherein the slave outer guide pipe is movably connected to the slave housing, and the end of the slave outer guide pipe away from the slave housing is fixedly connected to the slave end cover,

A drive for adjusting an adjustment element of a motor vehicle, the drive including a hollow cylinder, a rod guided axially therein, two articulated parts configured to provide linear drive movements to the motor vehicle and form a drive connection to the adjustment element and the rest of the motor vehicle. The one articulated part axially fixed to a first component of the components of the drive unit and the other articulated part axially fixed to a second component of the components of the drive unit in the installed state. The drive has a drive spring assembly including a drive spring acting on the articulated parts. In the installed state, at least one of the components of the drive unit is axially fixed to a securing element by a threaded connection, and the securing element projects radially into an axial projection of a spring material of the drive spring assembly.

Provided are a fireproof door apparatus, a fireproof structure, and a substrate treating facility. The fireproof door apparatus includes a fireproof shutter opening and closing a passage connecting two spaces, a release unit installed on one side of the passage and in the fireproof shutter and fixing the fireproof shutter in an open state using magnetic force or releasing the fireproof shutter that is fixed, and a gas spring connected to the fireproof shutter and moving the fireproof shutter toward the passage by heat of the fire to close the passage.

A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

In order to improve operability and user comfort for vertically sliding or displaceable facade components, a weight compensation device for vertically displaceable facade components includes a spring element for at least partial compensation of its own weight of a vertically displaceable facade component and a compensator. The spring element provides a spring force as a driving force (F.sub.AN) for lifting the vertically displaceable facade component. The spring element is movable between a compressed state (P.sub.K) and an expanded state (P.sub.E). The spring force has a decreasing value when moving from the compressed state to the expanded state. The compensator at least partially compensates for the decrease in the input force and provides an output force (F.sub.AB) that decreases less than the input force.

A vehicle hood hinge assembly includes a first bracket and a second bracket. The first bracket has a base flange and a side flange that extends upward from the base flange. The side flange has a rear end with a pivot shaft defining a main pivot axis. A front end of the side flange is spaced apart from the base flange and includes a pivot mount. The second bracket has a forward end and a rearward end. The rearward end is connected to the pivot shaft of the side flange of the first bracket for pivoting movement. A linear piston device is fixed to the pivot mount of the side flange of the first bracket. The second bracket is shaped and dimensioned such that during pivoting movements the linear piston has a non-contacting relationship with the second bracket.
