Abstract
PURPOSE: To seal up the space between a seat ring and a body by means of a seal ring formed by covering a spiral spring with a cladding metal.
CONSTITUTION: A seal ring 6 is formed by closely inserting an endless spiral spring 12 into cladding metals 11, the periphery of which is provided with a slit over its whole circumference. The seal ring 6 is pressed on the inner wall of a body 1 under the condition that the spiral spring 12 is compressed in order to seal up between the seat ring 3 and the body 1. Thus, when a ball 2 is expanded, the seat ring 3 can smoothly slide by following up the expansion. Also, the seal ring 6 can be applied over a wide temperature range because of being made of a metal.
