摘要： According to the present invention, a reaction-type turbine includes: a housing including a housing passage between an inlet and an outlet; a turbine shaft rotatably coupled to the housing to transmit torque; and at least one nozzle assembly coupled to the turbine shaft and rotatably provided in the housing passage. The nozzle assembly includes circumferential injection holes therein for injecting a high-pressure fluid in a circumferential direction and generating torque. Accordingly, when turbines having different capacities are manufactured, common parts can be compatibly used and assembling efficiency is improved. In addition, the eccentric rotation of the turbine shaft is prevented to significantly improve the durability of the reaction-type turbine. Furthermore, since the injection holes are long, the reaction-type turbine can be miniaturized and the efficiency thereof is improved.

摘要： The present invention relates to a reaction-type turbine. The reaction-type turbine of the present invention is configured such that a jet and rotating unit and a turbine shaft rotate by the repulsive force generated when steam spurts from the jet and rotating unit, so as to generate propulsion force. Thus, the operating stability of a steam turbine can be maintained even when condensate water is mixed with the steam, and manufacturing costs can be significantly reduced. Further, in order to reduce a loss of energy, the flow resistance of the steam is remarkably reduced or pressure leakage is prevented, thereby obtaining a low-cost and high-efficiency turbine.
