A stripper for ships' cargo tanks is arranged to operate without pumps. The stripper comprises a drain sump 9 having a discharge line 6 and an inlet 11 for inflow from the cargo hold. A compressed air line 13 extends into the drain sump. The inlet 11 can be closed by an automatic float element 12, by flotation, when there is sufficient liquid to fill the sump 9, and by the pressure of compressed air being supplied to the sump, via the pipe 13 when there is only sufficient liquid to fill the drain sump partly. The float 12 has a blind bore afforded by a tube 15, which bore receives loosely the outlet end part 14 of the line 13 so that the part 14 and tube 15 effectively operate like a piston and cylinder. <IMAGE> |
