HYDROMECHANICAL DRIVE Russian patent published in 2004 - IPC

Abstract RU 2238220 C2

FIELD: flying vehicle control systems.

SUBSTANCE: end face of plunger of cut-in valve is communicated through grooves and beads of spool valve with return hydraulic line and plunger is moved by spring to extreme position, thus ensuring cross-feed of chambers of hydraulic motor bringing them into communication with return line and disconnecting the inter-bead cavity of spool valve distributor from delivery hydraulic line. Provision is made for shift to mechanical control due to motion of input member, double-arm lever and cut-off valve of drive, i.e. imparting motion to control members by muscle force in case of seizing of spool valve distributor.

EFFECT: enhanced operational reliability of system.
