Abstract
A valve element for a small sized air pump. The valve element has legs, each of which are tightly secured within holes of valve-beds of a valve casing. A longitudinal hole is formed within each of the legs. The hole of the leg is opened at one end and closed at the other such that the hole terminates at a level horizontal to the lower surface of the valve-beds when the valve element is assembled.
