Pump esp. water pump has main part with integral magnetic exciting device to control magnet-regulated device to force fluid into and out of main part chamber

摘要

The pump has a main part (11) with chamber (111) having an intake (112) and an outlet (113). A magnetic exciting device generates a magnetic field to control a magnet-regulated device in the chamber, to suck the fluid through the intake into the chamber, and force it out through the outlet. The main part is of non-magnetic material. The magnetic exciting device is a stator (12) with silicon steel body (122) and coils (123), coils, a magnetic piston, and it has a magnet (13) and a rotor (14).
