<p>A hollow body (7) is associated with another hollow body to form a tap with a spherical obturator. The body comprises a circular section channel (9a) which extends along a principal direction (Dp). It has a hemispherical housing (11a) with an opening (12a) communicating with the channel centred on the same axis (D). There is an opening (16a), connecting to the other body, which is delimited by a connecting span (18a) and located opposite the communication opening. The connection opening has a circular contour with a diameter greater than the communication opening. The geometrical axis (D') of the connection span is parallel to and displaced relative to the geometrical axis of the communication opening.</p> |
