Title: Michio Idei: Innovator in Fuel Pump Technology
Introduction
Michio Idei is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of fuel pump technology, holding a total of 3 patents. His innovative designs have enhanced the efficiency and functionality of fuel pumps used in various applications.
Latest Patents
One of Idei's latest patents is for a motor type fuel pump. This design features an armature housing made of a substantially cylindrical plastic member, which is closed at the upper end. The pump chamber housing accommodates an impeller that is rotated by the armature, defining a pump chamber. The armature housing is designed to house motor components, including an armature, a commutator, and a cylindrical stator device consisting of a permanent magnet and a yoke. The inner surface of the armature housing has a plurality of ribs formed at predetermined angular intervals, which extend along its longitudinal direction. These ribs are fitted on the yoke of the stator device, allowing fuel to be supplied through a series of arcuated grooves defined by the outer surface of the yoke, the inner wall surface of the armature housing, and the ribs.
Another significant patent by Idei is for a shut-off valve for an electromagnetic pump. In this design, the inner end of an outlet pipe fixed in a pump housing extends a predetermined length inside a sleeve housing a plunger. This configuration forms a pump delivery pulsation absorption chamber around the outlet pipe. The inner end opening of the pipe is selectively closed by a control valve, which serves as a guide member for slidably guiding a valve body of a delivery valve along the axial direction. This innovative design simplifies the formation of the fuel leakage prevention control valve and the pulsation absorption chamber with a single construction.
