  • Safety system for a double acting servomotor
    Patent number: 4337689
    Abstract: The safety system employs a shut-off valve, a control valve and a selector. The selector is formed of two non-return valves which are connected to the two chambers of the servomotor and has an output connected to one chamber of the control valve. Another chamber of the control valve is connected to the low pressure chamber of the servomotor while the intermediate chamber is connected to the shut-off valve in order to influence the movements of the piston of the shut-off valve. A solenoid actuates the control valve to deliver either high pressure fluid from the high pressure servomotor chamber or low pressure fluid from the low pressure servomotor chamber to the shut-off valve.
