Definitions
- This invention relates to a thermostat assembly for cooling circulation systems of the internal combustion engines, to stabilise the coolant temperature in the range of engine's design.
- Wax type thermostats are most common solution on today's engines to keep the engine in proper temperature range. Their working method bases expansion of wax compound on, by temperature increasing. Wax compound is filled inside a wax capsule and it drives a piston top of the wax capsule expanding by temperature rise, this mechanism is called as thermo-actuator (or wax actuator). This expansion cause opening of a valve, which varies according the thermostat design. Combustion on engine causes over heating on engines and coolant consequently on thermostat. Wax compound, compressed inside a defined volume in thermo-actuator, expands. Expansion of the wax constitutes a linear movement by a piston. Linear movement of piston opens a valve, which oriented the coolant flow towards to radiator to reduce coolant temperature on the system for cooling the engine.

- FIG. 6 An application example of the invention: Open position of Thermostatic valve Figure 7 Cross-section view (C-C) of the application showing the coolant flow
- Thermo-actuator (comprising wax, wax capsule, piston)
- thermo-actuator (1) expansion and shrinkage of wax compound inside the capsule, by temperature change, creates a linear movement on thermo-actuator (1) piston, which its top is placed on housing (7), at vertical axis up or down.
- Thermo-actuator (1) is fitted among the nails inside flute of the valve (3), so that they move together. Movement of the Thermo-actuator opens or closes the valve (3).
- Valve (3) is guided inside the frame (4) by runners on the frame (4). Valve (3) makes its axial movement with thermo-actuator (1) inside the frame (4). Piston of the thermo- actuator (1) is placed on the housing (7) and frame is placed on cover (6) ( Figures 5-6- 7).
- thermo-actuator (1) there is a passage (8) between thermo-actuator (1) and valve (3) for coolant.
- the holes (9) generate a flow surrounds the thermo-actuator (1) continuously from the engine block to radiator on the engine. Since coolant flow surrounds the thermo-actuator (1), heat transfer is achieved directly to thermo-actuator (1) (figure 7). Rising coolant temperature heats wax compound inside the thermo-actuator (1), expansion of the wax compound inside the thermo-actuator moves piston and it opens the valve (3) without a late response time (figure 6). Opening of valve (3) generates a passage for coolant between valve (3) and housing (7) to radiator from engine block for cooling the coolant at radiator. In case of temperature drop on coolant, wax compound losses volume inside the wax capsule and spring (5) force closes the valve (3).
