<p>The element has a metallic housing (10) comprising an expansion material (14) that is mixed with an additive agent. Volume of the additive agent is dependent on temperature, and serves as a unit for driving a working piston out of the housing. Powder of an expanded graphite flake (15) is added to the expansion material about 50 percentage, and has percentage of weight of about 25 percentage. The powder is provided with particles with size of not less than 500 micro meter, and a sac-like membrane (11) is fixed to the element by a guide part (12). An independent claim is also included for a method for manufacturing a thermostatic working element.</p> |
