CA 2692385

The hydraulic linear actuator system of the present invention includes a pump that is configured to rotate in a single direction at a substantially constant velocity. Both the direction and flow rate of fluid through the system is controlled by adjusting the positional relationship between the stator and the rotor of the pump. This positional relationship is adjustable between a forward flow state, a non-flow state and a reverse flow state. The hydraulic linear actuator is responsive to the flow of fluid through the system so as to be displaced in a first direction by the forward flow state of the pump and in a second direction by the reverse flow state of the pump.

L'invention concerne un système actionneur linéaire hydraulique comprenant une pompe configurée pour effectuer une rotation à un sens unique à une vitesse sensiblement constante. Le sens et le débit de fluide à travers le système sont tous deux commandés par le réglage du rapport de position entre le stator et le rotor de la pompe. Ce rapport de position peut être réglé entre un état d'écoulement avant, un état de non-écoulement et un état d'écoulement inverse. L'actionneur linéaire hydraulique selon l'invention répond à l'écoulement de fluide à travers le système et il est déplacé dans un premier sens par l'état d'écoulement avant de la pompe et dans un deuxième sens par l'état d'écoulement inverse de la pompe.
