Waterjet cutting system fluid conduits and associated methods

A waterjet cutting system comprising:

• a waterjet cutting device coupleable to a pressurized water source of the waterjet cutting system, the waterjet cutting device including:
• a waterjet cutting head;
• and
• a fluid conduit configured to convey pressurized water to the waterjet cutting head, the fluid conduit including a wall defining a longitudinal passage through which the pressurized water travels, wherein the wall includes one or more longitudinally aligned through holes in communication with the longitudinal passage, and wherein:
• each of the one or more through holes has a cross-sectional shape with a maximum longitudinal dimension generally parallel to the longitudinal passage and a maximum latitudinal dimension generally perpendicular to the longitudinal passage, and
• the sum of the maximum longitudinal dimensions is greater than the largest maximum latitudinal dimension.

A fluid jet cutting device coupleable to a fluid jet cutting system, the fluid jet cutting device comprising:

• a fluid jet cutting head;
• a housing coupled to the fluid jet cutting head, the housing including:
• a body including an outer surface, a central passage, a fluid inlet aperture in the outer surface, and a fluid inlet passage extending from the fluid inlet aperture to the central passage;
• and
• a fluid conduit including a first portion positioned within the central passage and a second portion coupled to the fluid jet cutting head, one or more openings in the first portion proximate to the fluid inlet passage, and a longitudinal passage extending from the first portion to the second portion, wherein:
• each of the one or more openings is in communication with the longitudinal passage,
• each of the one or more openings has a maximum longitudinal dimension generally parallel to the longitudinal passage and a maximum latitudinal dimension generally perpendicular to the longitudinal passage, and
• the sum of the maximum longitudinal dimensions is greater than the largest maximum latitudinal dimension.
