摘要
Nozzle for mounting on the straight-shaped end of a concrete supply pipe consisting of articulated arms, for batching and ensuring the more uniform delivery, during operation, and for stopping delivery, during the rest condition, of concrete from the end of said pipe, said nozzle being formed by a hollow single-piece body made (1) of material which is yielding, with elastic properties, but resistant to deformation, comprising a cylindrical portion (2) to be fixed to the end of the pipe, by way of an axial extension thereof, and a substantially hemispherical (3) portion which is connected to the former by means of an enlarged portion and interrupted by a plurality of meridian cuts (5) which join together at an end hole.
