Реферат: A valve consists of a seat (5) with a plate (4). A ring (7) is so formed that it has an outer vertical flange (8) which encloses the seat (5). Three shorter, inner vertical flanges (9), positioned 120 deg. apart, form guides inside which the plate (4) can move up and down. Equally-spaced between the latter flanges (9), the ring (7) also has three tongues, forming leaf springs which press on the top of the plate (4), forcing it towards the closed position.
