Abstract
A suction pump, in particular a breast pump, comprises a bleed valve with a bleed opening, a bleed body which seals the bleed opening and an operating means for operating the bleed body. The bleed body may be operated such that upon opening the valve initially only a partial region of the bleed opening is released and subsequently a greater part thereof or the whole bleed opening is released. The suction pump provides a large functionality with the smallest size and, furthermore, is cheap to produce and easily assembled.
