Wax elements
WAX ELEMENT
Thermostatic elements convert change in temperature into mechanical motion. The expansion material is carefully obtain the required characteristics for each application. There are several ways the piston movement can be generated. The 3main technologies are know as « flat diaphragm », « squeeze push » and « annular / O’ring »
Flat diaphragm element
When heated the wax enclosed in the cup, expands and pushes against the diaphragm. The movement is transmitted via the plug to the piston. The guide maintains the diaphragm and allows the plug and piston to slide freely. An external spring ensures the return of piston when cooling down.
Squeeze-push elements
In this design, the piston is surrounded by an « elastomer bag ». When heated, the wax in the cup exands and pressure applies with the bag. Both radial force (squeeze) and an axial force (push) on the piston. Again, an external spring ensures the return of the piston when the temperature decreases.
Annular element
An annular element is shaped with a ring diaphragm. It reacts to temperature changes by expanding or contracting, commonly used to regulate fluid flow or control thermal systems.
