REACTION-TYPE TURBINE

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.
