Abstract
A movement control device comprising a housing with an elongate push rod mounted therein for reciprocal movement along a longitudinal axis between first and second positions, wherein the push rod extends out of said housing in both the first and second positions. A spring comprising a primary axis operable to provide a biasing force on the push rod is further provided in the housing. A damping device comprising a primary axis is located in the housing, wherein the damping device is in continuous engagement with the push rod through its reciprocating movement. The primary axis of the spring and the primary axis of the damping device are not coaxial.
