In the form shown, the lower portion c is cylindrical, the middle portion c<SP>11</SP> is toroidal internally, and the inlet valves are formed by an annular plate f. The latter may have peripheral guiding wings with rubber or other limiting and silencing buffers. According to the first Provisional Specification, the middle and lower portions of the siphon-bell may be continuously conoidal, and the inlet valves in the form of hinged flap valves.
