Abstract
A dampening cylinder is provided. The dampening cylinder includes a cylindrical housing defining a cavity for receiving a fluid therein. A piston slidably extends through the cavity in the housing and includes a flange projecting radially therefrom. The flange is positioned within the cavity so as to divide the cavity in the housing into first and second portions. First and second flow control valves control the rate of flow of fluid between the first and second portions of the cavity in the housing, and hence, the rate at which the piston slides through the housing. An emergency stop valve is positioned in fluid communication with the fluid flowing between the first and second portions of the cavity in the housing. The stop valve is movable between a first open position for allowing the flow of fluid between the first and second portions of the cavity in the housing and a closed position for preventing the flow of fluid between the first and second portions of the cavity in the housing.
