U.S. Patent 3,801,142 utilizes a cylindrical flexible latex tube which is compressed during assembly. The compressed latex tube functions to spring-load the two faces of the ceramic seal elements during operation. To better accommodate tolerance variation of other parts, the previously used latex tube can be substituted with a rubber tube having a bellows portion in the middle thereof, as shown in the above figure. Use of a bellows portion in the tube permits accurate seating of the ceramic seals with more controllable pressures, and accommodation of dimensional variation of components.
