Abstract
A blowing nozzle having a substantially parabolic blowing end is provided which entrains ambient gases into the output flow. A plurality of outlets are arranged so as reduce turbulence within the flow. The substantially parabolic blowing end converges at an apex coaxial with a blowing axis. A central outlet is provided at the apex to generate a core stream of gas. First outlets surround the central outlet. Second outlets surround the first outlets and are angled inward toward the blowing axis. Fins and/or additional outlets may be provided.
Claims20
A nozzle for blowing pressurized gas, the nozzle comprising:
- an elongate nozzle body having a supply end for receiving a supply of compressed gas and a substantially parabolic blowing end for blowing compressed gas along a blowing axis, the blowing end converging at an apex coaxial with the blowing axis;
- the blowing end comprising:
- a central outlet for generating a core stream of gas at the apex;
- at least three first outlets disposed at a first radius from the blowing axis, wherein:
- the first outlets are substantially parallel to the blowing axis and surround the core stream of gas, and
- the diameter of the first outlets is less than the diameter of the central outlet;
- at least three second outlets disposed at a second radius from the blowing axis, wherein:
- the second outlets are angled inward toward the blowing axis,
- the diameter of the second outlets is less than the diameter of the first outlets, and
- the second radius is greater than the first radius.
A method of generating a flow of compressed gases along a blowing axis from a nozzle having a substantially parabolic blowing end converging at an apex coaxial with the blowing axis, the method comprising:
- supplying compressed gas to an inlet of the nozzle;
- emitting a core stream of gas from a central outlet at the apex of the blowing end of the nozzle;
- emitting a first concentric stream of gas from the blowing end which surrounds the core stream, the first stream having a higher pressure than the core stream;
- and
- emitting a second concentric stream of gas from the blowing end which surrounds the first stream, the second stream angled inward toward the blowing axis and having a higher pressure than the first stream.
