Lockable gas spring
Dictator Technik

DICTATOR high-performance push type gas springs with additional locking raise objects, hold them in any position desired, and then release them again.

The locking push type gas springs are available in two types of locking. With cushioned locking the piston rod gives a little in the locked position so the object can recoil. These are easier to manufacture technically and are
therefore the more economic variety. If the object needs to remain in a fixed
position e.g. hospital beds that tilt, then gas springs with rigid locking must be used.

The locking is released by a pin at the front of the piston rod.
Releasing devices can be found on pages 06.043.00 and 06.044.00.
Other than the hospital bed shown in the drawing, further examples of where
locking push type gas springs are used include aeroplane seats and drawing boards etc.
DICTATOR locking push type gas springs can also be supplied with numerous additional options such as a valve, biological oil, protective tube and oil chamber.
