摘要： A servovalve device assembly is provided with an electronic matching circuit positioned upstream of the servovalve. The matching circuit supplies electric control signals whose purpose is to modify the hydraulic flowrate response curve of the servovalve as a function of the electrical control signal, so as to make it substantially identical to an ideal desired response curve.

摘要： The converter is designed to provide very great isolation between its input (AB) and its output (MN) in order to prevent disturbances in the input signal effecting the output signal.At the beginning of each cycle T as defined by a clock circuit (7), a switch (9) allows energy to be transmitted from the input (AB) to the output (MN) for a period of time t1 which is less than T. This period t1 is determined by a comparator (6) which receives a signal representative of the energy received by the input (AB) since the beginning of the cycle from a measuring circuit (1-5).Particularly applicable to protection against interference.
