Title: Magnetic fluid seal apparatus
Inventor: MIYAKE SHIYOUJIROU
IPC: F16J15/43
Filed: 1983-06-03
Abstract: PURPOSE:To provide a reliable magnetic fluid seal apparatus that will not be damaged by the repetition of the reciprocating motion by means of providing an obstacle to a movable shaft that obstracts the movement of the magnetic fluic to a pole piece. CONSTITUTION:A magnetic body 6 that has an annular groove in the center that constitutes an obstacle 7a is fixedly attached to a shaft 2. The outer circumference of the magnetic body 6 is discontinuous in the axial direction, and so, the obstacle 7a always constitutes a place where the magnetic field is weak relative to the movement of the shaft 2. Accordingly, it constitutes an inpassable obstacle for the magnetic fluid 5 to move onto a neighboring pole piece 4 as it is normally attracted to the magnetic filed. The inner diameter of the pole piece 4 is tapered, and by making use of the magnetic graduation effect in which the magnetic field becomes stronger toward the smaller diameter side, the magnetic fluid is returned to the smaller diameter side. 5' indicates the behavior of the magnetic fluid 5 when the shaft 2 moves to the low pressure side.
