STRAIGHTENING DEVICE AND FLUID NOZZLE

摘要

To provide a straightening device that is large in effective sectional area and has high straightening performance. This is a straightening device arranged in a fluid passage for making fluid pass through it that is provided with: a main body having an inflow port arranged in the fluid passage and for flowing the fluid into it, an outflow port for flowing the fluid out of it, and a communication passage for communicating the inflow port with the outflow port; and multiple projections that are arranged in a protruding manner toward a central part of the communication passage from an inner peripheral part and extend along the communication passage, in which the projections are each configured to have a narrower width in the central part than that in an inner peripheral part of the communication passage when seen from a flow direction of the fluid.

主权项

1. A straightening device arranged in a fluid passage that allows fluid to pass, comprising:
a main body that has an inflow port arranged in the fluid passage and for flowing the fluid into it, an outflow port for flowing out the fluid, and a communication passage for communicating the inflow port with the outflow port; and a plurality of projections that are arranged in a protruding manner toward a central part of the communication passage from an inner peripheral part and extend along the communication passage, the projections being each formed so that a width of the central part may be narrower than that of the inner peripheral part of the communication passage when seen from a flow direction of the fluid.
