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.
  • thermostats carry on this duty by closing and opening their valve on coolant flow passage from engine block to radiator; according to they are adjusted temperature to open or to close. They are adjusted for efficient engine temperature range. In case of higher temperature than the efficient engine temperature, thermostatic valve opens the flow to radiator for cooling of the coolant. On the lower temperature conditions, thermostatic valve stays at close position.
  • Wax type thermostats are most common solution on today's engines to keep the engine in proper temperature range. Their working method bases an expandable 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 temperatures, this mechanism is called as thermo-actuator. They adjusted to efficient engine temperature range by using proper wax compound, which its expansion temperature matches with the engine efficient temperature. This expansion cause opening of a valve for cold coolant by a mechanism, which varies according the thermostat design. Wax type thermostats constructions may vary.
  • thermostat assembly that comprises a typical wax actuator, a valve, a seal on the valve where valve seat on the housing to close coolant flow to radiator, a spring, which forces valve for closing when the coolant temperature drops down, a frame, which valve guided inside it.
  • FIG. 1 Exploded view of the thermostat assembly.
  • Thermo-actuator (comprising wax, wax capsule, piston)
  • thermo-actuator (1) expansion and shrinkage of wax compound inside the capsule, by temperature change, generates a linear movement on thermo-actuator' s (1) piston, which its top is placed on housing (14).
  • Thermo-actuator (1) is fitted among internal claws (13) inside the valve (3), so that they move together ( Figure 3 - Figure4). Press fitting of the thermo-actuator (1) among internal claws (13) strengthens the valve arms (5) and obstructs the stretching of them, to avoid disassembling of valve(5) from frame (9), which valve (3) is assembled by valve claws (6) inside the runners (12) of the frame (9).
  • Movement of the Thermo- actuator (1) opens or closes the valve (3).
  • Valve claws (6) are guided inside the frame (9) by runners (12) on inner surface of the cylindrical shaped frame (9).
  • Valve (3) makes its linear movement with thermo-actuator (1) by valve arms (5) inside the frame (9).
  • Piston of the thermo-actuator (1) is placed on the housing (14) and flange side of the frame (9) is placed on housing (14) by frame claws (10) placed in the channels on the housing (14) ( Figure 5).
  • frame claws (10) hold the thermostat stable inside the housing (14) and do not reflect the spring (7) force on the cover (15).
  • Outer skirts of the frame (9) is placed on the housing (14) and ensure the sealing between housing (14) and frame (9).
  • valve (3) By opening of the valve (3) from a big cross-section high coolant flow goes to radiator from engine block to reduce the coolant temperature on the radiator.
  • valve arms (5) go down through frame (9) and it is surrounded by the By-pass barrier (8) of the frame (9), so that it obstructs the flow towards to by-pass way on cooling system.
  • semicircle shaped passage (11) on the barrier (8) which ensures the temperature of the coolant around the Thermo-actuator (1) is same with the actual temperature of the coolant on the cooling system. This feature helps thermo-actuator (1) to move correctly according the actual system temperature.
