摘要： In the illustrative embodiment of the invention disclosed, a pressurized gas spring is arranged to provide three different damping-rate states as the piston rod is progressively urged axially outward of the cylinder. A first damping-rate stage is provided by an axially movable ring carried by the piston structure, a second stage is provided by an axially movable sleeve member slidably mounted on the piston rod for engagement at its inner end with the piston structure, and a third stage is provided by entry of the outer end of the sleeve member into a damping cylinder mounted adjacent the end wall of the cylinder through which the piston rod extends. The three damping-rate stages act cumulatively increasingly to slow outward movement of the piston rod. In the disclosed embodiment, the gas spring is mounted so as to be in the rod-down orientation when the piston rod is fully retracted, and the sleeve member is moved by gravitational force into engagement with the piston structure, thereby initiating the second damping-rate stage, when the gas spring moves to the rod-up orientation during use.

摘要： A pneumatic strut for use as an opening power assist mechanism for a motor vehicle tailgate has a piston rod extending from a piston contained within a cylinder. The piston separates the cylinder into two work chambers, each containing a gas charge under pressure. A bypass opening is active to connect the work chambers during the initial opening displacement of the tailgate to automatically open the tailgate through a first opening angle range. A second valve can be externally actuated to connect the two work chambers to further selectively open the tailgate into a second opening angle range. To close the tailgate, a third, directionally dependent valve can automatically connect the two work chambers during the closing displacement of the tailgate.

摘要： A gas spring in which a valve permits flow of a pressurized fluid between two compartments of a cylinder cavity separated by a piston for movement of a piston rod attached to the piston outward of the cavity while inward movement of the piston rod is normally blocked by a mechanism which responds to a predetermined, axial, inward force applied to the piston rod for releasing the same.

摘要： According to an illustrative example of the invention, a gas spring is combined with a telescopic tube which is axially slidable on the cylinder of the gas spring. The piston rod and the telescopic tube are provided at the respective most remote ends thereof with fastening eyes. The telescopic tube can be fixed in a plurality of positions with respect to the cylinder. For such fixation, the cylinder is connected with a carrier within the telescopic tube between opposite end walls of the cylinder and the telescopic tube. A locking bolt is guided within the carrier in a direction transverse to the axis of the telescopic tube. The locking bolt is engageable with a corresponding plurality of openings in the telescopic tube. The locking bolt is biased by a spring into an engagement position with respect to a respective opening and can be released from such engagement by being inwardly pressed by an operator.

摘要： In the illustrative embodiment of the invention as described an engine bonnet is articulated to the framework of a motor car. A gas spring is articulated to both the framework and the bonnet. The gas spring balances part of the weight of the bonnet when the bonnet is to be opened by hand. In case of an accident the framework and/or the bonnet may be crushed in longitudinal direction of the car. In such case the piston rod of the gas spring is pushed inward of the cylinder beyond the normal innermost operational position and a retaining device becomes effective so as to prevent the piston rod from returning towards its outermost operational position.

摘要： A gas spring arrangement in which conductive terminals on the cylinder and piston rod of a gas spring are connected by a conductive path insulated from the cylinder and piston rod. The path may be provided in part by contact elements on the cylinder and piston rod outside the cylinder cavity which engage each other when the piston rod approaches its axially terminal position during inward movement into the cavity. The path may also be provided in part by an insulated conductor helically wound on the piston rod in the cavity or outside. It may also include an axially elongated conductor secured to the axial cylinder wall outside the cavity.

摘要： In the illustrative embodiment of a current-carrying pneumatic spring disclosed, flow of electric current between external terminals on the cylinder member and piston rod member of the spring is provided by a contact element fixed on one of the members and carrying one or more contact faces which are resiliently biased into sliding engagement with an axially elongated face portion of the other member. Flow of electric current between the external terminals may thereby be provided over a range of positions or over all positions of axial movement of the piston rod member inward and outward of the cylinder cavity.
