Abstract
Provided is a screw device nozzle that can gas-cool a screw device effectively. A screw device cooling nozzle (4) of the present invention is placed in such a manner as to surround at least one of a screw shaft (1) and a nut (2). The cooling nozzle (4) includes an internal passage (8) into which gas is introduced, an opening (7) for releasing the gas flow introduced into the internal passage (8), a deflection surface (27), provided adjacent to the opening (7), for bending the gas flow released from the opening (7), and a guide path (10) for drawing in gas outside the cooling nozzle (4).
