Abstract:
A lift strut with directional damping comprising a housing comprising a wall that defines a housing chamber, the housing defining an axis; spring means located in the chamber; piston means movable through the chamber along the axis in a first direction and a second direction, the spring means biasing the piston means in the first direction, the piston means comprising a shaft, a seat connected to the shaft along the shaft length, and a resilient member fixed to the seat, the resilient element comprising at least one primary damping ridge and a damping tongue, each of the at least one primary damping ridges being in friction engagement with the housing as the resilient member is moved in the first and second directions, the damping tongue being in engagement with the housing wall when the resilient member is moved in the first direction and being located away from the housing wall when the resilient member is moved in the second direction.
