摘要： A gas pressure spring is provided including a working cylinder which, together with a slidably mounted compensating piston, encloses a working chamber filled with a working medium. A slidably mounted working piston is fastened to a working rod. In the event of a temperature increase, a compensating medium in a compensating chamber expands. The compensating piston is acted upon by the pressure of the working medium and the pressure of the compensating medium) such that the volume of the working chamber is increased. The temperature dependency of the gas spring force should be reduced by a design which is as simple as possible. For this purpose, the compensating chamber is at least partially surrounded by the working rod. Thus, the compensating medium can be compactly accommodated, and the assembly of the gas spring is simplified.

摘要： A shock absorber includes a housing and an end wall slidably disposed within the housing. The end wall and the housing cooperate to define at least a portion of a cavity within the housing. The cavity is filled with a fluid, and a piston is slidably disposed within the cavity. Movement of the piston within the cavity compresses the fluid to provide a spring force. The shock absorber further includes a compensator coupled to the end wall. The compensator positions the end wall within the housing to change a volume of the cavity in response to a change in a temperature of a first element of the compensator.

摘要： A temperature compensating valve assembly is provided that includes a bimetallic spring that deforms from a closed position to an open position in response to temperature, and a single-piece valve body having an aperture therethrough and having an open end for receiving the bimetallic spring. The single-piece valve body includes integral retainers for retaining the bimetallic spring in the open end in a location such that the aperture is blocked by the bimetallic spring when in the closed position and is not blocked by the bimetallic spring when in the open position.

摘要： A rail brake damper includes a cylinder-piston arrangement. A damping device assigned to the piston comprises at least one damping valve having at least one piston channel, which passes through the piston, connecting the two operating chambers of the cylinder, and a closure element assigned to the piston channel. The closure element is spring pre-loaded with the effect of closing the piston channel and is acted on by the hydraulic pressure which prevails in the operating chamber facing away from the piston rod with the effect of opening the damping valve.

摘要： A damper system for a vehicle is provided that includes a pressure tube and a piston assembly separating the pressure tube into first and second working chambers. A frequency dependent damper assembly, coupled to a piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a first valve assembly mounted to the piston assembly. The frequency dependent damper assembly includes first and second accumulation chambers that are separated by a floating piston. A second valve assembly, carried on the floating piston, controls fluid flow between the second accumulation chamber and the second working chamber. A bleed channel in the floating piston allows fluid flow between the first and second accumulation chambers, which reduces the adaptive force the plunger sleeve applies to the first valve assembly during high frequency, low velocity rebound inputs.

摘要： A pneumatic spring strut assembly comprises a cylinder comprising a working end and a boosting chamber. The working end includes a first volume of gas and the boosting chamber includes a second volume of gas. A temperature control valve assembly is disposed in the interior volume separating the working end from the boosting chamber and includes an over-pressure valve configured to release the second volume of gas into the working end when the pressure within the boosting chamber increases above the normal pressure range of operation. A valve is disposed in the wall of the cylinder, in the working end thereof, and is configured to yield, to thereby vent the first volume of gas to atmosphere, when the pressure within the interior volume of the working end increases above the normal pressure range of operation.

摘要： The disclosure relates to a damper device comprising a cylinder, a piston bearing on one side of the cylinder, a piston rod displaceably received by the piston bearing, and a bottom unit on another side of the cylinder. The cylinder, the piston bearing and the bottom unit form a closed chamber that is filled with a compressible liquid. The piston rod subdivides the chamber into first and second chamber halves between which the liquid can be displaced if the piston rod is displaced relative to the cylinder. Furthermore, the closed chamber provides for a variable volume so as to compensate temperature-induced pressure fluctuations inside the closed chamber.
