Claims

[Scope of utility model registration request]

A diaphragm that partitions the automatic air supply device main body into a first chamber that communicates with the suction side of the pump and a second chamber that communicates with the inside of the pressure tank; a spring that biases the diaphragm toward the second chamber; an air intake valve that sucks air into the second chamber when the second chamber has a negative pressure; and a level that is inserted into the pressure tank to a predetermined size and communicates the second chamber with the pressure tank. The automatic air replenishment device for a well pump having a pipe includes a float valve chamber that communicates the second chamber with the level pipe, and a float provided between the automatic air replenishment device main body and the level pipe. a valve chamber body, and a float valve that is arranged in the float valve chamber and closes a passage to the second chamber when water in the pressure tank is sucked into the float valve chamber through the level pipe. , a conduit having the level pipe installed therein and connecting the pressure tank and the float valve chamber body, the level pipe being made of an elastic material and having a flange formed at its upper end; An automatic air supply device for a well pump, characterized in that a space between the float valve chamber body and the conduit is sealed.
