Heat expansion compensation element

摘要

The element consists of a ring (1) with high heat expansion coefficient, and a ring-shaped piston (2), sliding in a chamber (1.1) In one of the parts to be protected. Chamber, ring, and piston are located in a connection plate (1.3). The chamber is formed by a recess (1.2) In the plate. It is located between an inner and an outer holding ring, which are pressed together. The element ring has rounded or bevelled outer edges, and the piston is also rounded. The machine part enclosing the chamber, and the piston, consist of the same material.
