摘要： A steam turbine valve drive apparatus in an embodiment includes a piston, a cylinder, a bidirectional pump, a servo motor, and a quick closing mechanism. The cylinder houses the piston in an inner space thereof, the inner space being partitioned by the piston into a first hydraulic chamber and a second hydraulic chamber. The quick closing mechanism executes a quick closing operation of closing the steam valve unit more quickly than the closing operation. Here, the quick closing mechanism executes the quick closing operation by feeding the working oil accumulated in an accumulator to the second hydraulic chamber and draining the working oil from the first hydraulic chamber.

摘要： The actuator (50) comprises a slide (52) carrying at least two stages (54, 56) and being capable of sliding in a cylinder and two control chambers (62, 64) connected to respective use holes (U1, U2) of an electrically controlled servo-valve hydraulic distributor (20). The control chambers (62, 64) are each situated on one side of a respective stage and an intermediate chamber connected to high or low pressure is situated between the other sides of the stages. In the event of electrical control failure, the distributor (20) slide is taken to a safety position in which the control chambers (62, 64) of the actuator (50) are at the same low or high pressure opposed to that applying in the intermediate chamber (66) so that each stage of the actuator slide is then subjected to high pressure on one side and to low pressure on the other side. Sealing between each actuator slide stage (54, 56) and the actuator cylinder (60) is carried out by a dynamic seal (70) producing a frictional force between stage and cylinder, depending on the difference between the pressures exerted on the two sides of the stage so that, in the event of electrical control failure, the actuator slide valve is immobilized in its position at the moment of the failure (“fail freeze”). The actuator (50) can be an aeronautical engine fuel metering unit.

摘要： The invention relates to a hydrostatic variable unit with a servo system bringing about the control of the hydrostatic unit and with a valve unit controlling the servo system, the valve unit comprising two magnetically actuated proportional pressure-reducing valves which respectively act upon one of the sides of a servo system, which sides operate counter to each other, and having a safety function which, in the event of an incident, transfers the servo system into a safety position. The safety function is realized by at least one of the proportional pressure-reducing valves being designed at the same time as a pilot valve for activating and deactivating the second proportional pressure-reducing valve.
