Abstract

Improvements in the check valves of the drain pumps made up of a check valve made totally or partially of a non-rigid material and arranged to be placed around the periphery of a tube-shaped part 1 that has on its periphery some openings 6, characterized in that it has a ring shape with at least two parts thereof 2-3 at an angle to each other and in which the free end of the first part 2 is arranged so as to form a hermetic seal around the periphery of part 1 and in which the free end of the second part 3 is arranged so that it remains in contact without clamping, either with part 1 in a circumference that is axially displaced with respect to the contact circumference of the first part 2 with said part 1, or with a disk or ring 5 that can be placed in contact with part 1, so that the openings 6 of part 1 are between the contact circumferences of the two parts 2 and 3 with part 1 and with part 1 or with the disc or ring 5 respectively.
