Self-centering conduit cleaning device with reduced axial length

An apparatus for use in cleaning an associated conduit, said apparatus comprising:

• a body comprising a central portion, a forward end comprising a neck, and a rear end comprising a hose fitting adapted for connection to an associated hose;
• said body comprising an axially extending main flow passage that extends through said hose fitting, through said central portion, and through said neck such that said main flow passage opens through both said forward and rear ends of the body;
• said neck comprising threads for connection of an associated conduit cleaning nozzle to said neck for fluid communication with said main flow passage;
• a centering device connected to said body, said centering device comprising a core and a plurality of fins that project outwardly from said core, said core of said centering device comprising a mounting bore, wherein at least part of said hose fitting is located within said mounting bore of said core and an annular space is defined between said hose fitting and an inner surface of said mounting bore of said core.

A conduit cleaning device comprising:

• a body comprising a rear portion including a hose fitting adapted for connection to an associated hose;
• said body comprising a main flow passage that extends through said hose fitting;
• a centering device secured to said body, said centering device comprising a core and a plurality of fins that project outwardly from said core, said core of said centering device comprising a mounting bore, wherein at least part of said hose fitting is located within said mounting bore of said core and an annular space is defined between said hose fitting and an inner surface of said mounting bore of said core;
• said centering device comprising a resilient elastomeric structure and said core of said centering device being resiliently deflectable relative to said hose fitting;
• said body comprises at least one transverse flow passage that intersects and fluidically communicates with said main flow passage;
• said cleaning device further comprising a thrust orifice in fluid communication with said transverse flow passage.
