VARIABLE DIFFUSER OF COMPRESSOR

摘要

A variable diffuser of a compressor is provided to simplify the configuration of a bracket connecting a shaft and a rotating ring. A variable diffuser of a compressor comprises: a shaft(210) having a straight-line motion to vertical direction of a principal axis by the driving of a motor; a rotation ring(220) covering the principal axis and combined to the shaft and a hinge; and a diffuser ring(230) positioned at an inside of the rotating ring. A protrusion part(223) is formed at one side of an inner circumference of the rotating ring or an outer circumference of the diffuser ring, and an inclined recessed part(231) in which the protrusion part is inserted is formed at the other side. The diffuser ring is moved to the longitudinal direction of the principal axis by the rotation of the rotating ring. A plurality of guide pins(115) is formed at a casing to movement direction of the diffuser ring. A plurality of guide groove is formed at the diffuser ring along the circumference. A guide plate is inserted into the guiding groove.
