The present disclosure provides a compressible fluid device (1), such as a gas spring. The device comprises a casing (11) defining a compression chamber (12), a piston (15), which is movable in the chamber (12), and a safety member (2) placed in such a manner as to be struck by the piston (15) in the event of the piston overstriking, whereby at least some of the compressible fluid is evacuated from the compression chamber (12). The device further comprises a pre-strike member (25), that is arranged to be struck before the safety member (2) is struck, such that the safety member (2) is only struck once a predetermined overstroke force has been achieved.

Provided is a method for manufacturing a vibration damping device including sealing liquid (L) in a liquid chamber (11) of a vibration damping device main body (10) having the liquid chamber (11) in which the liquid (L) is sealed, and an injection port (12) through which the liquid (L) is injected into the liquid chamber (11). In a state where a nozzle (22) spouting the liquid (L) is thrust into the injection port (12) and an inside of a decompression container (21) having the vibration damping device main body (10) disposed therein is decompressed, the liquid (L) is injected into the liquid chamber (11) through the nozzle (22), and air inside the liquid chamber (11) is discharged through an air discharge port (14) which is formed in the vibration damping device main body (10) and communicates with the liquid chamber (11).

A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.

A gas cylinder actuator with overtravel safety device, comprising a tubular jacket for gas containment, which is closed hermetically at one end by a bottom provided with a gas filling valve and at the opposite end by a head portion, which is provided with a hole for the passage of a stem with a piston, the jacket, the bottom and the piston forming the gas expansion and compression chamber. The head portion comprises an annular body, which is fixed internally to the jacket, and is provided with a central hole for the passage of the stem with the interposition of dynamic sealing elements, static sealing elements being interposed between the annular body and the jacket and an element for controlling the descending motion of a slider of a press with which the actuator is associated being provided and protruding from the annular body or from the jacket, the control element being preset to selectively move or break or deform in order to break or deform or render ineffective in general the static and dynamic sealing elements.

A pressure-balanced shock absorber has an outer tube, an inflatable base, a piston tube, a valve adjusting rod, a piston base, an inner tube, and an adjusting resilient element. The inflatable base has a valve passage and a first valve core. The first valve core selectively seals the valve passage. The piston tube communicates with the valve passage. The valve adjusting rod is movably mounted in the valve passage of the inflatable base and the valve tube. The piston base is connected to the piston tube and has a piston passage. A second valve core selectively seals the piston passage. The inner tube is mounted around the piston tube. The piston base divides the inner tube into a first air chamber and a second air chamber. The adjusting resilient element is disposed in the piston tube to achieve the effect of inflating two air chambers.

End member assemblies are dimensioned for securement to an end of a flexible spring member for forming gas spring assemblies. An end member assembly can include an end member body and at least one connector fitting. The end member body includes a base section and a cap section that are secured together at a single flowed-material joint. The base section and the cap section together at least partially define a reservoir chamber within the end member body. The at least one connector fitting is at least partially embedded within the end member body. Gas spring assemblies including at least one end member assembly and suspension systems including at least one gas spring assembly are also included.

A shock absorber having an outer tube, an inner tube disposed coaxially in the outer tube and a piston reciprocally mounted in the inner tube. The interior of the inner tubes forms a working chamber for hydraulic oil while an annular replenishment chamber is formed between the inner and outer tubes. An improved base plate and base cage assembly facilitates fluid flow from the replenishment chamber to the working chamber during an extension cycle of the shock absorber.

A shock strut includes a first cylinder defining a first volume. The shock strut includes a first piston head moveably positioned within the first volume and defining a first fluid chamber and a third fluid chamber within the first volume. The shock strut includes a second cylinder defining a second volume. The shock strut includes a second piston head moveably positioned within the second volume and defining a second fluid chamber and a fourth fluid chamber within the second volume. The fourth fluid chamber is in fluid communication with the third fluid chamber. The shock strut also includes a bleed port. The shock strut also includes a tube extending from the fourth fluid chamber through the second piston head and the second fluid chamber to the bleed port.

An adjusting device includes a connecting member having a chamber. The connecting member further includes first and second openings defined in two ends thereof and communicated with the chamber. The connecting member further includes a first assembling portion in the chamber and a threaded portion in the second opening. A through-hole extends from an inner periphery through an outer periphery of the connecting member and communicates with the chamber. An adjusting member includes a pivotal end having a second assembling portion for assembling with the first assembling portion. The adjusting member further includes a passage having first and second openings respectively in two ends thereof. The first opening of the adjusting member is located in the pivotal end. A sealing cap is in threading connection with the threaded portion. A damper and a damp adjustment cylinder can be coupled to the adjusting device to form a vehicular shock absorber.

A cylinder device includes a cylinder, an outer tube, a piston, a piston rod, a rod guide, a first common passage through which working oil that is supplied/discharged to/from a rod-side chamber passes, a pipe that forms a part of the first common passage and is provided in a reservoir tank, a pipe holder that is provided between the pipe and the rod guide and holds a first end of the pipe, and a plug that is provided on a side of the pipe holder opposite from the pipe and has a throttle passage allowing the first common passage to communicate with the reservoir tank.
