<p>The invention relates to a cock comprising: a body (10) including an axial tube (11) and a transverse cylindrical recess (13) of axis (D2) which is perpendicular, traversed right through by this tube; and a key (20) including, on the one hand, a shut-off part in the form of a cylindrical rod (21), housed in the cylindrical recess of the body and provided with a through passage (22) of axis (D3) perpendicular to the axis (D2) of the rod and, on the other hand, an operating part (23) emerging laterally from the body, so as to allow the key to be rotated with respect to the body. According to the invention, the key is produced from a moulded material, for example a filled polyacetal and carries elastically deformable single-piece sealing members (26, 27), for example made as a single piece with the key or overmoulded in grooves of the key which have been formed previously as a result of moulding, so as to constitute a cock with a cylindrical plug essentially made from two elementary pieces. <IMAGE></p> |
