| 20090267344 | WATER PUMP HAVING A SPHERICAL BALL COUPLING - The present invention relates to a swimming pool water pump having connection couplings for connection to fluid flow piping for the purpose of circulating a fluid, preferably for a swimming pool or for a swimming bath, at the fluid suction orifice of the pump and/or at the fluid delivery orifice of the pump, said pump having at least one said connection coupling integrated into the pump at the said delivery orifice or at the said suction orifice, said coupling having a spherical ball ending in an inclined cylindrical tubular end-piece suitable for inter-fitting with the end of a said fluid flow pipe, so that the axis of said cylindrical end-piece of said spherical ball coupling can pivot in all directions through an angle α varying from −αmax to +αmax relative to the axis of said delivery orifice or of said suction orifice of the pump, where αmax is at least equal to 20°, preferably lies in the range 25° to 60°, and more preferably lies in the range 30° to 45°. | 10-29-2009 |
