Реферат: 16,646. Foster, A. le N. July 30. Tyres, pneumatic. - An inflating-valve is shown in section in Fig. 1. The head b of the valve casing a has an air passage f, and is recessed to receive a leather or similar washer. The valve casing has a very fine internal screw-thread into which screws the hollow valve stem m, of which the inner end h is closed and slightly reduced in diameter. Transverse air passages i allow the air to pass from the pump round the closed end h into tyre, when the valve stem occupies the position shown. The valve is closed by screwing down the stem on the washer. A non-return valve o may be employed, or this valve may be replaced by a slit rubber tube placed on the reduced end of the stem.
