Abstract
PURPOSE: To greatly reduce the driving energy and eliminate seizing, by fitting a rotary closed ring, which is opposed to a fixed closed ring through a swept-in passage, axially movable to the periphery of an annular body fixed to a shaft.
CONSTITUTION: When the clearance of a swept-in passage 9 between two closed rings 2, 5 becomes almost zero, the pressure of fluid X at a position A on the left side of an annular body 4 is nearly equal to that of a chamber 14 in a housing 1. Since D9 is also nearly equal to D4, no thrust force works on the closed ring 5 and no contact pressure is generated at the contact between both rings 2, 5. As the clearance between surfaces 7, 8 is negligible, fluid that leaks out is also negligible. If both rings 2, 5 are separated from each other to expand the clearance of the swept- in passage 9, the pressure of fluid X flowing from a passage 10 to the chamber 14 is lowered and the ring 5 is pushed back to other ring 2.
