Abstract
A piston and cylinder type damper with a cylinder containing damping fluid. The damper is operable to perform a compression stroke and a return stroke. A piston rod that can engage with both a piston assembly and a return means. A sealing element is movable axially with respect to said piston rod such that said sealing means is operable to engage with both said piston assembly and said return means, such that, in said compression stroke the sealing means engages solely with said piston assembly, and in said return stroke engages solely with said return means.
Claims16
A piston and cylinder type damper having a cylinder containing damping fluid operable to perform a compression stroke and a return stroke, the damper comprising:
- a piston rod engagable with a piston assembly and a return means, wherein said piston rod is operationally disposed with respect to a sealing means axially movable with respect to the piston rod such that said sealing means is operable to engage with both said piston assembly and said return means, such that, in said compression stroke the sealing means engages solely with said piston assembly, and in said return stroke engages solely with said return means, wherein:
- the sealing means is an O-ring, wherein the O-ring is in floating arrangement with the piston assembly and the return means,
- the return means comprises a spring and an optional support member, wherein the spring engages with the piston rod and the sealing means either directly or indirectly via the optional support member, and
- the piston assembly comprises a central aperture, and wherein the central aperture is substantially encircled by a flow channel.
A piston and cylinder type damper operable to perform a compression stroke and a return stroke, the damper comprising:
- a piston rod;
- a piston assembly, and
- a return means,
- wherein the piston rod and the return means are operable to engage in both the compression and return strokes independent of the piston assembly,
- wherein the return means comprises a spring, and
- wherein the piston assembly comprises an aperture therethrough, and wherein the piston rod includes a portion that is operable to pass through the aperture and directly engage with the spring.
A piston and cylinder type damper comprising:
- a piston rod comprising a flange and a piston rod pin;
- a return means;
- a sealing means;
- and
- a piston assembly, wherein, the piston rod pin has a length that is longer than the combined length of the sealing means and the piston assembly, when compared along a primary axis of the damper, and
- wherein the piston rod pin engages with the return means on both a compression stroke and a return stroke, and both said sealing means and said piston assembly are operable to float with respect to the return means and the piston rod.
