Gas spring incorporating a safety member

A compressible-fluid device, including a compression chamber and a piston that is movable in said chamber, the device comprising a safety member disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to cause the compression chamber to be drained when said safety member is struck by the piston, said safety member being secured to a hollow plug screwed into a body of the device.

A compressible-fluid device including a compression chamber and a piston that is movable in said chamber, the device comprising a body, a threaded plug screwed into a bore in said body disposed so as to be struck by the piston in the event of the stroke of said piston being greater than a predetermined nominal stroke, said plug being arranged so as to cause the compression chamber to be d rained when said safety member is struck by the piston, and a protective screen is fastened onto said body of the device.

A gas spring including a chamber containing a gas and a piston that is movable in said chamber to compress said gas, wherein a safety member is disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to cause the gas contained in said chamber to be drained when said safety member is accidentally struck by the piston.

A gas spring including a chamber filled with a gas and a piston that is movable in said chamber to compress said gas, a casing and a plug screwed in a bore of said casing, said plug being disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said plug being arranged so as to cause the gas contained in said chamber to be drained when said safety member is struck by the piston.

A compressible-fluid device, including a casing, a compression chamber containing a compressible fluid and a piston that is movable in said compression chamber in a first direction for compressing said compressible fluid and in a second direction opposite the first direction in response to a force of compressed fluid, the device comprising a safety member disposed in a through bore of the casing so as to be struck by the piston in the event of stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to cause the compression chamber to be drained when said safety member is struck by the piston.

A compressible-fluid device, including a compression chamber containing a compressible fluid and a piston that is movable in said compression chamber in a first direction for compressing said compressible fluid and in a second direction opposite the first direction in response to a force of compressed fluid, the device comprising a safety member disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to cause the compression chamber to be drained when said safety member is struck by the piston, the piston having a face facing the safety member, said face being provided with a central recess.

A compressible-fluid device, including a compression chamber containing a compressible fluid and a piston that is movable in said compression chamber in a first direction for compressing said compressible fluid and in a second direction opposite the first direction in response to a force of compressed fluid, the device comprising a safety member disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to break when struck by the piston so as to cause the compression chamber to be drained.

A compressible-fluid device, including a casing, a compression chamber containing a compressible fluid and a piston that is movable in said compression chamber in a first direction for compressing said compressible fluid and in a second direction opposite the first direction in response to a force of compressed fluid, the device comprising a safety member rigidly fixed on said casing and disposed so as to be struck by the piston in the event of a stroke of said piston being greater than a predetermined nominal stroke, said safety member being arranged so as to cause the compression chamber to be drained when said safety member is struck by the piston.
