Fastener for elements of differential heat expansion - consists of clamping screw and intermediate spring on low expansion element

摘要

The fastener is intended e.g. for an IC engine heat exchanger and its holder. It secures an element (2) of high heat expansion to a low expansion member (1) via an intermediate spring (6). The spring is tensioned by a clamping screw (3,4) which passes through the high heat expansion element, while maintaining a radial distance. The spring is coupled to the low expansion member, and the connector has a screw with a limiting stop, formed by a sleeve (5) surrounding the screw. The spring supports itself via a removable distance disc (7) on the screw head, or the high expansion element. An additional spring may be located between the two elements.
