A suction pulsator (1) used to periodically generate a vacuum in a container connected to it, especially in a collection container for mother's milk, which is provided with a suction funnel. A central nozzle hole (25) of a nozzle body (20) is provided, wherein a compressed air flow flows through the nozzle hole (25) and the nozzle body (20) is concentrically surrounded by a ring-shaped suction gap (35), wherein the nozzle (25) opens into a narrow, radial outlet gap (36), which is formed between a radial deflecting surface (40), which guides the compressed air flow over the suction gap (35), and annular surfaces (29, 30) of the nozzle body (20) and of a nozzle jacket (13), which concentrically surround the nozzle hole (25) and the suction gap (35). The suction gap (35) opening openly into the outlet gap (36) is in connection with a suction line (39), which can be connected to the collection container through a connection opening (38), which is arranged away from the outlet gap (36). |
