Method for producing a thermostatic work element and thermostatic work element

摘要

The element (10) has an elongated housing (11) comprising a cylindrical, tube-shaped housing body (12) and a single-piece base (13). An expansion material (15) is provided in an inner side of the housing, where volume of the material is temperature-dependent. The material serves as a medium for driving a working piston (16), and an additive (18) consisting of ground natural-graphite is added to the expansion material. The working piston is provided with a cylindrical pin, and a heat-conduction increasing unit is arranged in the housing, where the unit has metallic conducting elements. An independent claim is also included for a method for manufacturing a thermostatic working element.
