ABSTRACT:
A spring-loaded dampening actuator includes a cylindrically-shaped body member, a piston rod, a coil spring, and a one-way lip seal member. The lip seal member engages an inner sidewall of the body member only when a force is applied by means of a coil spring so as to push the piston rod out from the body member at a dampened or controlled rate of speed.
