Title:
NOZZLE CONTROLLER OF VARIABLE NOZZLE TYPE TURBO-CHARGER
Document Type and Number:
Japanese Patent JP3323062
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To alleviate friction by removing a play between parts which makes slide contact with each other and to render smooth the operation thereof in linking device.
SOLUTION: One of the members which slide contact in a linking mechanism constituting a nozzle controller is a fork-like end part 2b of a link plate 2 which is connected to a plurality of peripheral nozzle vanes of a turbine rotor 10 to be able to be rotated. Then, in the case where the other member is a driving piece 4e projecting inward from a first rotary link plate 4 which is driven and rotated with an actuator 8, an engaging piece 5a of a second rotary link plate 5 to which a definite direction energizing force f is given with a compression spring 12 is engaged with a fork-like end part 2b to alleviate friction on these slide friction surfaces. With such a structure, a slit between the driving piece 4e and the engaging piece 5a is expanded so that a play with the fork-like end part 2b becomes zero. Incidentally, the compression spring 12 may be a pull spring.
