摘要： The invention relates to a double-circuit hydraulic system for controlling consumers of mobile equipment such as track equipment. Two hydraulic circuits (2, 4) can be interconnected by means of a system provided with interconnection valves (38). According to said invention, a device such as non-return valve makes it possible to ensure that, a high pressure in the circuit supplying reduced quantity of a pressure fluid does not impact another circuit having a low pressure, the circuits (2, 4) being interconnected. In the preferred embodiment, the inventive system provided with interconnection valves comprises two manometers (40, 42) which are exposed to a pumped pressure and the load pressure of the corresponding circuit, the non-return valves being arranged upstream thereof.

摘要： A hydraulic actuating device, for example for a retractable hard-top of a convertible car, comprising a double-acting hydraulic actuator, the first connection of the actuator being in communication with an associated throttling assembly which is designed to provide, for hydraulic fluid passing through the first connection, either an optionally controllable throttling or a clear passage opening.
The throttling assembly has a pressure-detection means for detecting the hydraulic pressure in the second working chamber, which pressure-detection means has associated with it a predetermined switching pressure.
The throttling assembly is designed in such a manner that - when pressurized hydraulic fluid is being supplied to the said second working chamber - the clear passage opening is active if the detected pressure in the said second working chamber is above the switching pressure and that the throttling is active if the detected pressure in the said second working chamber is below the switching pressure.
