Abstract

The invention relates to a fluid-operated rotary-vane device (actuator or pump), comprising a casing (3) traversed by a rotary shaft (1). A double vane (6, 6'), capable of rotating with the shaft, and two fixed partitions (5, 5') determine inside the casing two chambers (4a1, 2, 4b1, 2) of a complementarily variable volume. The vane is formed by a parallelepipedal bar attached to the shaft (1), which shaft is entirely cylindrical. The partitions (5, 5') are integral with a cover plate belonging to the casing. A very low level of inter-chamber leakage is maintained without an internal seal. <IMAGE>
