Method for producing a thermostatic work element and thermostatic work element

摘要

#CMT# #/CMT# 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. #CMT# : #/CMT# An independent claim is also included for a method for manufacturing a thermostatic working element. #CMT#USE : #/CMT# Thermostatic working element. #CMT#ADVANTAGE : #/CMT# The expansion material serves as the medium for driving the working piston, and the additive consisting of ground natural-graphite is added to the expansion material, thus improving response time of the working element in a simple and cost-effective manner, and maintaining the response time of the element over long duration, without changing the reaction time. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a thermostatic working element. 10 : Thermostatic working element 11 : Elongated housing 12 : Tube-shaped housing body 13 : Single-piece base 15 : Expansion material 16 : Working piston 18 : Additive.
