Valve on receptacle, especially milk trough for feeding calves

摘要

The housing has openings (8') at least one of which is positioned along the centre axis and the other along the periphery. A circular flexible disc (3) when pressure is exerted on it by a pressure medium conveyed into the housing through a pipe (4) closes and opens the openings. The housing has a first plate (5) with passage through (6). The edge of the flexible disc is clamped tightly between the first and second (7) plate with an opening in the middle. The flexible disc is elastically deformable by the pressure medium towards a third plate (8) parallel to the second plate and connected to an opening (9) in the receptacle and closed by the deformed flexible disc.
