Abstract (en)
A door control unit (100) provides real time continuously variable damping capacity to respond to changing conditions of weather, wear and use. By incorporating an electronic programmable controller (30), the door control unit always operates at optimum efficiency due to continuously variable fluidity of the control fluid within the control unit. <IMAGE>
