SWIVELING ARRANGEMENT

摘要

A swiveling arrangement with a swiveling element swivelable around an axis powered and damped by a gas spring having a cylinder filled with gas and divided into first and second working chambers by a piston that has a piston rod guided through the second working chamber and a guiding and sealing unit. A first connection opened during an outward stroke of the piston from the second to the first working chamber, and a second connection is opened during an inward stroke from the first to the second working chamber that has a smaller cross-sectional flow area than the first connection. An auxiliary piston separates the second working chamber from an auxiliary chamber. A third connection from the auxiliary chamber to the second working chamber opened in the end move-out stroke and a fourth connection from the second working chamber to the auxiliary chamber opened in the move-in stroke.

主权项

1. A swiveling arrangement comprising:
a swiveling element configured to perform a swiveling movement between a vertically upwardly directed inoperative position and a horizontally directed operative position around a swivel axis arranged at the one end region of the swiveling element; a gas spring configured to power and damp the swiveling movement of the swiveling element and configured to moved out in the inoperative position and moved in in the operative position, comprising: a cylinder filled with gas under pressure; a guiding and sealing unit, a displaceable piston arranged in an interior of the cylinder and dividing the cylinder into a first working chamber and a second working chamber; a piston rod extending from one side of the displaceable piston, the piston rod guided outward in a sealed manner through the second working chamber and the guiding and sealing unit; a first connection configured to be opened during an outward stroke of the piston that leads from the second working chamber to the first working chamber; a second connection configured to be opened during an inward stroke of the piston that leads from the first working chamber to the second working chamber and which has a smaller cross-sectional flow area than a cross-sectional flow area of the first connection; an auxiliary piston arranged in the cylinder and displaceably arranged on the piston rod that separates the second working chamber from an auxiliary chamber formed in the cylinder; a third connection from the auxiliary chamber to the second working chamber opened in an end move-out stroke region of the piston; a fourth connection from the second working chamber to the auxiliary chamber opened in a move-in stroke of the piston, wherein a cross-sectional flow area of the third connection is smaller than across-sectional flow area of the fourth connection.
