Abstract
Provided is a compressed air jet device A composed of an discharge port member 1 provided on a pipe P for connecting to a compressed air supply source such that the opening thereof faces downwards, and a hole portion 14 provided in the connection 10 between the pipe P and the discharge port member 1 and allowing communication between the interior of the pipe P and the interior of the discharge port member 1, wherein the vertical cross-sectional shape of the peripheral wall 2 of the discharge port member is formed so that the interior side and/or the exterior side of the discharge port member are inclined to have a smaller wall thickness towards the free end of the opening 1a.
Claims8
A compressed air jet device comprising a pipe communicated with a supply source of compressed air and an discharge port member provided on the pipe, wherein the discharge port member is formed in a cup shape in which a top part thereof is connected to the pipe and an opening faces outward in a radius direction of the pipe, and on a connection of the pipe and the discharge port member, a hole portion is formed to communicate an interior of the pipe and an interior of the discharge port member;
- the compressed air jet device wherein a vertical cross-sectional shape of a peripheral wall forming an opening of the discharge port member is formed so that a wall surface of any one of or both an interior or an outside of the discharge port member inclines toward an tip end of the opening to reduce a wall thickness;
- and wherein a plurality of the recesses are formed at intervals in a circumferential direction of the peripheral wall, and a rib is formed between the recesses along a longitudinal direction of the peripheral wall.
