Claims (7)
- REVENDICATIONS1. Servovalve hydraulique (1) à deux étages comprenant : -un étage de puissance comprenant un organe mo- bile de distribution de puissance (7), - un étage de pilotage comprenant un moteur cou- ple (MC) comportant un rotor (3) lié à un émetteur ou un déflecteur de fluide hydraulique (4), et un organe de ré- troaction (6) déformable et opérationnellement relié au rotor (3) et à l'organe mobile de distribution de puissance (7) pour établir entre eux une liaison mécanique, caractérisée en ce que l'organe mobile de distribution de puissance (7) comprend des moyens de pincement (8) de l'organe de rétroaction (6) qui sont conformés pour auto- riser un déplacement d'une partie pincée de l'organe de rétroaction (6) relativement à l'organe mobile de distribution de puissance (7) au moins suivant une direction transverse à un effort de pincement généré par les moyens de pincement (8).
- 2. Servovalve selon la revendication 1, dans laquelle les moyens de pincement (8) comprennent au moins une vis de pression (17).
- 3. Servovalve selon la revendication 1, dans le- quel les moyens de pincement (8) comprennent deux vis de pression (17) montées en opposition.
- 4. Servovalve selon la revendication 1, dans laquelle les moyens de pincement (8) comprennent des tiges métalliques (18) s'étendant en porte-à-faux et ayant des extrémités pinçant l'organe de rétroaction (6), de sorte à autoriser le déplacement de la partie pincée de l'organe de rétroaction (6) sous l'effet d'une flexion des tiges métalliques (18).
- 5. Servovalve selon la revendication 1, dans la- quelle, l'organe mobile de distribution de puissance (7)étant sensiblement cylindrique, les moyens de pincement (8) sont implantés dans un alésage (14) réalisé dans cet organe mobile de puissance suivant un axe de révolution dudit organe (7).
- 6. Servovalve selon la revendication 1, dans la- quelle l'organe de rétroaction (6) est une tige.
- 7. Servovalve selon la revendication 1, dans laquelle l'organe de rétroaction (6) est une lame.
