摘要： A fluid-filled piston-cylinder unit with a tubular fluid-filled housing closed at one end and with a piston rod emerging from the other end comprising, for guiding the said piston rod, a guide bush which is sealed on the one hand against the inside wall of the housing and on the other against the piston rod by the use of seals. Provided at the inner end of the piston rod there is a guide piston. In order on the one hand to avoid surface pressure between the piston rod and the guide bush and on the other to achieve an adequate length of guidance for the piston rod itself, the guide bush is provided with at least one spacer extending in axially parallel manner beyond the seals and in the direction of the guide piston and the cross-section of which is substantially smaller than the cross-section of the guide bush.

摘要： An adjustable-length gas spring has two compressed-gas-filled cylinders concentrically surrounding one another, with a piston and piston rod disposed in the inner cylinder thereof. A valve for effecting communication between housing chambers divided by the piston is provided at one end of the cylinders. This valve has a valve body, which is sealed with respect to the cylinders by means of outer ring seals. In order to avoid the danger that the gas spring may become useless from damage to one of the outer ring seals, it is provided that the valve body embodied as an injection-molded plastic part tapers--optionally in gradations--towards its axial ends, without radial protrusions, beginning at a region between the two outer grooves, that the outer groove associated with the inner cylinder is axially defined with respect to the adjoining housing chamber by the cap which is directly connected to the valve body and that the outer groove associated with the inner wall of the outer cylinder is defined axially with respect to the outside of the gas spring by a separate ring that is firmly joined to the valve body.

摘要： A piston for a piston cylinder unit, particularly a gas spring, is to be provided with a piston ring and comprises a portion extending at least from the piston ring groove to a free end and consisting of a plurality of segments separated from one another by longitudinal slots. This portion is provided with a bore the diameter of which is at the free end smaller than the diameter of the related portion of the piston rod. It is the purpose of these measures to enable simple assembly of the piston ring in the piston ring groove and at the same time to ensure reliable seating of the piston ring.

摘要： A lockable elevating mechanism for the continuous adjustment of chair seats or the like comprises a guide tube, in which a length-adjustable, lockable gas spring is slidably guided. The piston rod of the gas spring is connected to the bottom plate of the guide tube. The housing of the gas spring is guided by means of a guide sleeve in the guide tube, the guide sleeve having a central carrying tube, in which slide sleeves are arranged with space. The carrying tube is surrounded by a carrying sleeve held in the guide tube. Thus a gas spring is obtained, on the one hand, which is free of bracing, resistant to wear and with good sliding qualities, and, on the other hand, the manufacturing of the guide sleeve is favorable in terms of material expenditure.
