Claims

[Scope of utility model registration request]

The outer periphery of the diaphragm attached to the end of the vertically oriented shaft is attached to the casing, a coil stand is integrally formed around the shaft, the coil is supported on the coil stand, and the coil is fixed to the casing side. Insert movably into the gap between magnetic circuit members,
A diaphragm is made up of a conductive coil spring that causes current to flow through the coil, which is loosely wound around the shaft, the conductive coil spring elastically biases the shaft upward, and the weight of the shaft, coil, and diaphragm is borne by the elastic force of the conductive coil spring. pump.
