Claims (1)
によりその翼間に発生する作動流体の二次流れを
バイパスするシユラウドを有するタービンであつ
て、タービン翼を固定するシユラウドに翼通路内
及び翼出口部を連絡するバイパス穴を少なくとも
１つ以上穿設してなるパイパス穴付シユラウドを
有するタービン。 A turbine that has a shroud that bypasses the secondary flow of working fluid generated between adjacent turbine blades due to the pressure difference between the ventral surface and the back surface of the blades, and the shroud that fixes the turbine blades has a section inside the blade passage and a blade outlet. A turbine having a shroud with a bypass hole, which is formed by drilling at least one bypass hole connecting the parts.
