Title: Pump
Inventor: MARUYAMA TERUO
IPC: F04D29/046
Filed: 1979-12-27
Abstract: PURPOSE: To eliminate wear and permit a steady flow characteristic to be maintained by providing a very compact and simple construction where a motor and pump are made to one body and formation a spiral groove serving both as a fluid bearing and for forcing fluid.  
     CONSTITUTION: An opposing type induction motor is constructed with a thin plate rotor 2 and a stator 2 provided on the outer side. Thus, the entire pump can be made very simple, thin and compact. The rotor 1 is also formed with a spiral groove, which serves to force out fluid and also as a bearing supporting the rotor 1. The rotor 1 is thus mechanically supported in a noncontact state while it is rotated. Thus, the noise when driving the pump is low. Also, no wear occurs since there is no mechanical frictional part. Further, fluctuations of the discharge pressure versus flow characteristic is prevented to permit stable, low rate and high precision supply of fuel.
