Locking gas springs Varilock

The locking gas springs, also called gas pressure springs, gas dampers or gas pressure dampers, aid the ergonomics and comfort for conveniently safely changing seated and lying positions, for effortlessly and precisely operating machine covers and are used in many other applications.

Our lockable gas springs make it possible to variably lock them in any stroke position, whether elastically ("spring-loaded") or rigidly. Our special functions offer particular advantages when it comes to convenience and operation.

Different connection elements and release systems complete our range of products and give you the appropriate lockable gas spring for any application.

Functionality


What is a locking gas spring? How is a locking gas spring built and what forces act in the pulling and pushing direction when locked? We present the most important characteristics of the locking gas springs to you here:

  • What is a locking gas spring?

    Locking gas springs are hydropneumatic adjustment elements.

  • Structure of a locking gas spring

    They consist of a pressure pipe and a piston rod with a piston as well as a valve that is actuated via the release pin.

  • Extension force of the locking gas spring

    When the valve is opened, the extension force aids the user in adjusting his or her application in that the gas spring bears a large part of the weight force. When the valve is closed, the gas spring locks, thus locking the application in the desired position. Depending on the design, the locking can be elastic or rigid. With the help of the elastic locking, the lockable pneumatic spring responds in a spring-loaded manner in the push and pull direction, since this is only filled with nitrogen. 

     

    With rigid locking, the locking gas spring reacts rigidly in the push and pull direction. This is achieved by a defined oil chamber in which the piston moves. The locking force in the pushing or pulling direction is maximized depending on the arrangement of the chamber.
