Embodiment Construction

[0022] The tension spring shown in the figure has a cylinder 1 which is divided by a guide 2 into a gas chamber 3 filled with gas under pressure and a hydraulic chamber 4 filled with hydraulic fluid.

[0023] One end region of the guide part 2 is connected to a piston rod 5 which protrudes from the cylinder 1 through the hydraulic chamber 4 and a guide and sealing unit 6 , which seals this hydraulic chamber from the outside.

[0024] The guide 2 has an axially extending cylinder chamber 7 which is divided by a steam piston 8 into a steam chamber 9 adjacent to the gas chamber 3 and a spring chamber 10 remote from the gas chamber 3 .

[0025] The diameter of the steam piston 8 is smaller than the inner diameter of the cylinder chamber 7 .

[0026] The cylinder chamber 7 is also filled with hydraulic fluid and is connected to the inner chamber of the cylinder 1 , which is closed at its end side close to the gas chamber 3 by a bottom 11 . The end of the cylinder chamber 7 facing ...

Abstract

The tension spring has a cylinder (1) which is divided in a gas chamber (3) and a hydraulic chamber (4) by a piston, where the gas chamber is filled with a gas stands under pressure. The hydraulic chamber is filled with a hydraulic liquid. The piston is formed as a guide piece (2) which has a coaxially extended filled cylindrical chamber (7) filled with hydraulic liquid.

Description

technical field [0001] The invention relates to a tension spring with a cylinder, which is divided by a piston into a gas chamber filled with gas under pressure and a hydraulic chamber filled with hydraulic fluid; a piston rod connected to the piston, the piston rod Sealably protrudes from the cylinder through the hydraulic chamber. Background technique [0002] Such tension springs are used in particular for closing doors or flaps of furniture. [0003] Such tension springs have the disadvantage that they have a long construction length and thus require a large installation space. Contents of the invention [0004] It is therefore the object of the invention to provide a tension spring of the type mentioned at the outset, which has a short overall length and is of simple construction. [0005] According to the invention, this object is achieved in that the piston is a guide with a coaxially extending cylinder chamber filled with hydraulic fluid, in which a steam arrange...
