Abstract
An improved fluid pressure reduction device including a perimeter and a hollow center aligned along a longitudinal axis, and further including an inlet region at the hollow center and an outlet region at the perimeter, wherein the outlet region includes multiple dimensioned outlet areas arranged to substantially reduce outlet tone generation.
Claims22
A fluid pressure reduction device comprising:
- a hollow housing defining an inner surface and an outer surface;
- an inlet section comprising a plurality of inlets disposed at the inner surface being operatively couple to outer surface via internal passageways;
- and
- an outlet section comprising a plurality of outlets being disposed at the outer surface and operatively coupled to the internal passageways to provide a fluid path from the inner surface to the outer surface, the outlets defining at least a first outlet area and a second outlet area such that the plurality of outlets are arranged to substantially reduce an outlet jet interaction.

A fluid pressure reduction device comprising:
- a hollow housing defining an inner perimeter and an outer perimeter;
- a plurality of inlets disposed at the inner perimeter and being operatively coupled to the outer perimeter via internal passageways;
- and
- a plurality of outlets disposed at the outer perimeter and being operatively coupled to the internal passageways to provide a fluid path from the inner perimeter to the outer perimeter, the outlets having at least a first dimensioned outlet and a second dimensioned outlet, the outlets being dimensioned such that a first outlet jet velocity of the first dimensioned outlet is substantially dissimilar to a second outlet jet velocity of the second dimensioned outlet at a pre-determined radial distance from the outer perimeter.

A fluid pressure reduction device comprising:
- a hollow housing defining an inner perimeter and an outer perimeter;
- a plurality of inlets disposed at the inner perimeter and being operatively coupled to the outer perimeter via internal passageways;
- and
- a plurality of outlets disposed at the outer perimeter and being operatively coupled to the internal passageways to provide a fluid path from the inner perimeter to the outer perimeter, the outlets having at least a first dimensioned outlet and a second dimensioned outlet, the outlets being positioned on the outer perimeter of the housing such that the at least first dimensioned outlet and the at least second dimensioned outlet are arranged to substantially reduce a peak acoustic frequency produced by the fluid pressure reduction device.
