摘要： A fluid damper is provided including a cylinder filled with a damping fluid, a piston base body shiftably guided in the cylinder along a stroke axis, and a valve disk spaced apart from a shell wall of the cylinder. The piston base body divides an inner space of the cylinder into a front space and a rear space along the stroke axis. In the piston base body, there is at least one channel connecting the front space to the rear space in a fluid-conducting manner. The valve disk is shiftably guided along the stroke axis between an opening position unblocking the at least one channel and a closing position closing the at least one channel. The valve disk has a central area extending radially outward from the stroke axis, the central area being free of apertures.

摘要： 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.

摘要： A lateral arm assembly and method of operation includes first and second articulating arms comprising first and second ends, the first ends of the articulating arms are mounted upon assembly to a support surface at separate lateral locations. The first ends each comprise separate pivoting mounting structures for forming a first pivotal connection with the first and second articulating arms. The lateral arm assembly also comprises a roller tube having spaced lateral ends supporting respective end brackets that provide a second pivotal connection to the second ends of the articulating arms. The roller tube supports a canopy coupled to a roller shaft, wherein one of the end brackets further supports a device that drives the roller shaft for furling and unfurling the canopy.

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 piston cylinder device (1) comprising a cylinder (2) with a first and a second end and a guide (6), such that a pressure chamber (8) is formed in the cylinder. A piston (12) is moveable in the pressure chamber (8). The guide (6) is fixedly secured to the cylinder (2) by a lock ring (7). A sealing means (9) is arranged to seal between the guide (6) and an inner wall of a tubular wall (3) of the cylinder (2) to prevent fluid leakage from the pressure chamber (8) to the surroundings. The piston cylinder device (1) is provided with a material weakening zone (13) arranged in the inner wall of the tubular wall (3) of the cylinder (2) axially between the lock ring (7) and the second end (20) of the cylinder (2), the material weakening zone (13) being arranged to be deformed or sheared against the lock ring (7) at a predetermined level of impact of the piston (12) against the guide (6). A leakage gap (14) is arranged to interrupt the sealing means (9) upon deformation or shearing of the material weakening zone (13) such that gas from the pressure chamber (8) is allowed to leave the pressure chamber (8) through said leakage gap (14) to the surroundings.

摘要： A retractable wheel system includes a rotatable member, a swing arm attached to the rotatable member and a wheel, a swing mount attached to the rotatable member, and a spring member. The spring member is attached to the swing mount at a connection point on a first end and to the swing arm on a second end. The spring member is rotatable relative to the swing mount at the connection point. The spring member is configured to apply a force in an upward direction when the connection point is above a line extending between a wheel attachment point and a swing arm rotation point of the swing arm and a force in a downward direction when the connection point is below the line of the swing arm. A transportation unit including the retractable wheel system is also disclosed.
