valve for controlling the flow of a medium from a first system to a second system, pump device for transporting a medium from a first system connected to its inlet to a second system connected to its outlet, and, extractor device The method of the present invention relates to a valve (1) for controlling the flow of a medium from a first system (24) to a second system (26) comprising a deformable bell-shaped structure (3) forming a reservoir (25) and including a flow path opening (9), a valve cap (5) including a first connector opening (15) for connecting the valve (1 ) to the first system (24) and a contact element (23) for interacting with the flow path opening (9) to open and close it, and a valve base (7) which is hermetically connected to the valve cover. (5) and the structure in formed (3), and including a second connector opening (17) for connecting the valve (1) to the second system (26) and which is coupled to the reservoir (25). the deformable bubble housing (3) is configured such that, in an open state of the valve (1), the deformable bubble housing (3) is deformed, and the flow path opening (9) does not be connected to the contact element (23) to allow flow from one medium of the first system (24) to the second system (26) through the first (15) and second (17) connector openings and path opening (9), and in a closed state of the valve (1), the deformable bubble housing (3) is in its original bubble housing and the flow path opening (9) is connected to the contact element (23) and thus closed. The present invention further relates to a pump device (47) and a milk extractor device (41) including a valve (1) as described above. 1/2resumo válvula para controlar o fluxo de um meio a partir de um primeiro sistema para um segundo sistema, dispositivo de bomba para transportar um meio a partir de um primeiro sistema conectado à sua entrada para um segundo sistema conectado à sua saída, e, dispositivo extrator de leite para extração de leite da mama de uma lactan
