Abstract

The drain element for collecting hydrocarbons comprises a screen (TM) surrounding a suction cylinder (CA) extending in a longitudinal direction (AL). The screen is made up of rods (TT, TC) which extend along said longitudinal direction (AL) and which are regularly spaced apart around the suction cylinder. At least one of said rods is hollow in order to form a collector rod (TC), said collector rod (TC) having a lateral orifice and communicating with the inside of the suction cylinder via one of its ends.
