A baffle plate (41, partition member) is manufactured by being integrally formed of a single material including flexible or pliable NBR (nitrile rubber), and a projection (51) formed on an abutment surface (42B) of the baffle plate (41) is fitted into a recess (52) in a reduced-diameter portion (36) of an intermediate tube (20). Thus, when the intermediate tube (20) fitted with the baffle plate (41) is assembled into an outer tube, the sheet-shaped baffle plate (41) can be prevented from rotating about a connecting pipe (23), and it is possible to improve the productivity and assembleability of the shock absorber.

An air bleed system for a suspension fork or shock absorber includes: a fluid passage between an interior of the suspension and an exterior of the suspension; and a manually operable valve having a first position substantially closing the fluid passage and a second position allowing fluid flow between the interior and the exterior.

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.

An adjustable vibration damper has at least one adjustable damping valve, a piston at a piston rod that divides a cylinder into a work chamber on the piston rod side and a work chamber on the side remote of the piston rod. A hydraulic device is connected via a first line to the at least one adjustable damping valve connected to one of the work chambers and via a second line at least indirectly to the other working chamber.

A production method for a cylinder device includes a first liquid injection step of injecting a first predetermined amount of working fluid L into the inner cylinder, a first piston rod insertion step of inserting an assembly between the piston rod and the piston into the inner cylinder to dispose the piston at a predetermined position inside the inner cylinder, a second liquid injection step of injecting a second predetermined amount of the working fluid into an upper side of the piston inside the inner cylinder, and a closing step of closing the opening of the outer cylinder with the closing member.

An industrial gas spring with a pressure chamber in a casing with an end wall, a piston rod received at least in part in the casing for reciprocation between extended and retracted positions and a pressure relief assembly carried by the end wall. The pressure relief assembly may have a membrane communicating with the pressure chamber and a plunger configured to breach the membrane when engaged and moved by the piston rod when it overtravels its design intended retracted position.

An air bleed system for a suspension fork or shock absorber includes: a fluid passage between an interior of the suspension and an exterior of the suspension; and a manually operable valve having a first position substantially closing the fluid passage and a second position allowing fluid flow between the interior and the exterior.
