Claims

[Scope of utility model registration request]

A tire phragm that partitions the automatic air supply device 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, and 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 an air intake valve that is inserted into the pressure tank to a predetermined size to communicate the second chamber and the pressure tank. In the automatic air replenishment device for a well pump having a level pipe, a spring receiver made of an elastic body is disposed between the lower end of the spring and the upper end surface of the diaphragm in contact with the upper end surface of the diaphragm. An automatic air supply device for a well pump, characterized in that a hard plate is arranged between the receiver and the spring.
