Title:
SECTION-VARIABLE NOZZLE RING FOR SUPERCHARGER
Document Type and Number:
WIPO Patent Application WO/2019/200950
Kind Code:
A1
Abstract:
A section-variable nozzle ring for a supercharger, comprising a mounting disc (1), a backing plate (2), a shifting disc (3), and shifting forks (4). Blades (5) are annularly arranged between the mounting disc (1) and the backing plate (2); the shifting disc (3) drives the blades (5) to rotate by means of the shifting forks (4); one end of each of the plurality of shifting forks (4) is connected in one-to-one correspondence to one blade (5) and synchronously rotates with same, and the other end is bent downward and inserted into the shifting disc (3); the mounting disc (1) is provided with an annular groove (6) on the side surface, and the inner side of the shifting disc (3) is inserted in the annular groove (6); the bottom surface of the annular groove (6) is a curved surface. By adjusting the rotation angle of the blades (5), the section of the air flow can be adjusted, and the shifting disc (3) is closer to the mounting disc (1), so that the overall nozzle ring is thinner, the structure is more compact, and the reliability and flexibility of the shifting disc (3) are also higher.
