HYDRAULIC MACHINE Russian patent published in 2001 - IPC

FIELD: hydraulic machines; propeller turbines; marine propellers at adjustable blade angle. SUBSTANCE: chamber contains oil in the amount not exceeding the amount of oil pressed to wall of hub body during rotation of rotor; it fills the volume which has form of bowl between blade trunnions in axial section. When turbine shaft is in vertical position, inner surface of oil is slightly inclined downward and inside under action of gravity force; as a result some amount of oil is rubbed into settler. Suction branch pipe running to pump is located in this zone. Running from pump is pipe line, then hose and return pipe line running to articulation from which return pipe line runs to oil receiving trough or to respective unit, thus providing for proper lubrication of bearings and other parts of hub which are to be lubricated and reducing leakage of oil to minimum and consequently reducing danger of oil escape to surrounding medium. EFFECT: enhanced efficiency. 11 cl, 4 dwg
