Abstract

PURPOSE: To prevent wear of a bearing for the adjustable-vane shaft of an axial flow or mixed-flow pump and to thereby obtain smooth rotation of the adjustable vanes, by feeding lubricating oil forcibly with the movement of a control rod for the adjustable vanes.
CONSTITUTION: When a control rod 5 is moved downward for changing the angle of adjustable vanes, a piston 22 fixed to the control rod 5 is also moved downward, so that an oil suction valve 23 at an upper portion of a cylinder 21 is opened but an oil discharge valve 25 also at an upper portion of the cylinder 21 is closed. On the other hand, an oil suction valve 24 at a lower portion of the cylinder 21 is closed but an oil discharge valve 26 slso at a lower portion of the cylinder 21 is opened. Resultantly, oil in a chamber located on the lower side of a piston 22 is forced to flow into an oil passage 28 in an adjustable vane 6a via a resilient pipe 27 and then to the sliding surfaces of bearings 17a, 17b of the adjustable vane 6a.
