HYDROSTATIC OPERATING MODE HYDRAULIC ACTUATOR PREFERABLY FOR BACKUP OPERATION, AND FLIGHT CONTROL SYSTEM COMPRISING IT |
摘要 |
An hydraulic actuator composed of a double-acting actuator, a mobile switching member disposed in a housing connected hydraulically to the actuator, two fluid inlet and outlet pipes and a control member adapted to command the mobile switching member to move between a neutral configuration and an active service configuration. A variable speed pump system is connected to the housing by an auxiliary circuit; the mobile switching member has an active second configuration in which the actuator communicates with the auxiliary circuits, whereby the actuator, the pump system and the auxiliary circuit constitute a hydrostatic transmission.
