Kind Code:
A
Abstract:
A system for limiting the force of reaction in hydraulic servo-control devices in which there is provided an actuating member as well as a power output member, with the power output member being relatively movable in relation to the actuating member and communicating with a servo-motor provided with working or operating spaces in which the relative movement which results between the actuating member and the power output member is effected for activating a valve mechanism which connects the working or operating spaces interchangably with a pressure source or a drain in the sense of amplifying means. Reaction members are provided for reacting upon the actuating member and the reaction members are stressed in the reaction chamber by the pressures of the working spaces or their proportional pressures up to a predetermined value, and are then subjected, by a pressure-limitation, of a pressure only which is of a substantially constant value.
