## Abstract

A fluid outlet structure includes cavities formed in both inner sidewalls of the outlet having control fluid passages from which control fluid is jetted toward a center of the outlet to deflect fluid flowing through the outlet. According to the invention, the fluid outlet structure comprises one or more supplementary fluid control members including supplementary cavities having respective supplementary control fluid passages, and communicating pipes for communicating the cavities in the sidewalls and supplementary cavities of the supplementary fluid control members having the fluid passages opening in the same directions, thereby obtaining deflected fluid flows with great deflecting angles.

## Claims

### Claim 1

A fluid outlet structure using a fluid element including a supply opening for supplying compressed fluid, an outlet opening corresponding to said supply opening for fluid exhaust, a main fluid passage formed between said openings and control fluid passages comprising cavities provided in sidewalls on inner opposite sides of said main fluid passage, two supplementary fluid control members, each having two supplementary cavities divided by a center wall forming a T-shaped body in each said supplementary fluid control member, each said supplementary cavity having a supplementary control fluid passage communicating with said main fluid passage, and two communicating pipes, each communicating with said cavity in one of said sidewalls and one of said supplementary cavities of said supplementary fluid control members remote from said sidewalls, so that each said supplementary control fluid passage causes control fluid from said control fluid passage of one of said sidewalls to flow against the other sidewall.

### Claim 2 (depends on 1)

A fluid outlet structure as set forth in claim 1, wherein an upstream wall of said cavity in each said sidewall is formed with an aperture for receiving said compressed fluid as a control fluid into said cavity and a magnetic vlave is provided to close or open said aperture.

### Claim 3

A fluid outlet structure using a fluid element including a supply opening for supplying compressed fluid, an outlet opening corresponding to said supply opening for fluid exhaust, a main fluid passage formed between said openings and control fluid passages of cavities provided in sidewalls on inner opposite sides of said main fluid passage, a supplementary fluid control member having supplementary cavities and supplementary control fluid passages in said main fluid passage, and communicating pipes for communicating said supplementary cavities with said cavities in said sidewalls, so that each said supplementary control fluid passage causes control fluid from said control fluid passage of one of said sidewalls to flow against the other sidewall, said supplementary fluid control member having a T-shaped cross-section and two said supplementary cavities therein divided by a center wall and each said communicating pipe communicating said cavity of one of said sidewalls with one of said supplementary cavities remote from said one of the sidewalls.
