The distribution valve (1) in a polymer material is made up of a valve body (5). An operating rod (4) is traversed by a passageway (6a,6b), which extends outside of the body and is held in compression by springy material (11) made in a single unit from a elastomer material. The body (5) defines an internal chamber (8) which communicates with the passageways (6a,6b) and a suction pipe (9). The springy material (11) being lodged at the bottom (5a) of the chamber.
