A cylindrical perforated member is mounted between a working fluid inlet port 6 and a hermetic vessel 1a that a working fluid supplied into the hermetic vessel at the working fluid inlet port will not directly contact the forced-feed liquid surface. At the working fluid inlet port is mounted a ring-shaped member with a divergent section having the smallest flow passage area. The working fluid stream is deflected and dispersed by the cylindrical perforated member, to produce a pressure for feeding the liquid rapidly within the hermetic vessel, thus enabling the rapid forced-feed of the liquid. <IMAGE> |
