SYSTEM WITH NO PRESSURE OR ELECTRICAL TRAVEL CUSHION AIR TANK VALVE PRV HIGH PRESSURE AIR SOLENOID (TYPICAL) DEPRESSURIZED PRESSURIZED RETRACTED RETURN DEPRESSURIZATION PISTON SPRINGS HYDRAULIC FLUID DEPRESSURIZED HYDRAULIC FLUID PRESSURIZED DIAMOND-SHAPED ACTUATOR (DSA) AT MINIMUM VOLUME DISPLACEMENT PISTON (DP) AT MAXIMUM VOLUME Electrical power and pressurization is initiated for drive stage (Page 13). The green arrows indicate fluid flow caused by the force differential between the Diamond-Shaped Actuator and the displacement piston when pressurized in the driving stage. The green arrows indicate fluid flow caused by the air pressure in the cushion tank in the second recharge stage (Page 15). The purple arrows in recharge stage one indicate fluid flow caused by the return springs when depressurized. The return springs have pulled the DSA back to minimum fluid volume when depressurized. 15.338
