The invention relates to a device (101) for dispensing a fluid including: - a tank (2) arranged so as to contain the fluid; - a dispensing pipe (8) arranged so as to guide the fluid in a dispensing direction (10); - a dispensing opening (105) connecting the tank to the dispensing pipe ; - a dispensing valve (5) which, in an open state, allows fluid to pass from the inside of the tank (2) to the dispensing pipe (8) via the dispensing opening (105) and, in a closed state, does not allow fluid to pass from the inside of the tank (2) to the dispensing pipe (8); and - a return means (29) arranged so as to exert a force on the dispensing valve (5). Said force moves the dispensing valve (5) from the open state thereof to the closed state thereof. The return means (29) includes a pouch (106) forming a cavity (107). Said pouch is located in the dispensing pipe (8). The shape of the pouch is changed via compression when the dispensing valve is in the open state. |
