DESCRIPTION
THERMOSTAT ASSEMBLY WITH SELF AIR BLEEDING VALVE Technological Area
This invention relates to a thermostat assembly with an air bleeding valve for cooling circulation system of the internal combustion engines which' s cage is created by the body of the thermostat mechanism instead of using additional parts to discharge the air collapsed in the engine before coolant charge it in.
Known Situation of the Art
In the internal combustion engines with liquid coolant, over heating that occurred by burning of fuel is transferred via coolant, which is circulated through channels in engine block and cylinder head. By this way engine can run in proper temperature range. Thermostat assemblies are used to control this circulation. To provide a proper circulation, it is important to have a stable circulation system. One of the main points to have a stable circulation system is to discharge the air collapsed in the circulation system. Thus in most of engine designs, placing air bleeding valves are preferred.
There is two type of solution which is mostly used in today's thermostat assemblies: Air bleeding valve with jiggle pin and air bleeding valve with ball. For air bleeding with jiggle pin, there is a small hole in the valve disc to assist in bleeding the system as filling takes place. The jiggle pin closes the hole during engine warming up. For air bleeding valve with ball, a cage is needed to guide the ball and a ball is guided inside of this cage. And a gap is placed upside of this cage. It allows discharging the air until is sealed by the ball. The ball seals the gap by the help of coolant pressure of the coolant circuit. Brief Description of the Invention
With this invention, it is aimed to obtain a thermostat assembly has an air bleeding valve without need of mounting the valve to the thermostat assembly.
The air bleeding valve is formed when an upper body and a lower body are assembled to each other. In this way savings are provided in the meaning of production process, time and costs. The structure of air bleeding is more durable and long lived due to being combined structure with upper and lower bodies.

- At least a lower body (2) which has at least a lower cage (2), air bleeding inlet (211) and guide (22),
- At least a lower cage (21) encloses the ball (B) from a bottom face and has at least an air bleeding inlet (211) which the ball (B) is placed in and moves along its center,
- At least an upper body (3) which has at least an upper cage (31), air bleeding outlet (311) and extension (32),
- At least an upper cage (31) encloses the ball (B) from a top face and has at least an air bleeding outlet (311) which the ball (B) is placed in and moves along its center,

- At least an extension (32) which fits the guide (22) to provide that lower cage (21) and upper cage (31) are assembled on an axis.
Thermostat assembly with self air bleeding valve (1) is based on a cage mechanism for air bleeding valve with ball (B). The cage mechanism is created directly by protruded from the lower body (2) and upper body (3) instead of using or mounting an extra cage structure. The ball (B) is placed in the cage mechanism before the assemble or mounting of lower body (2) and upper body (3).
Lower body (2) comprises lower cage (21), air bleeding inlet (211) and guide (22). Lower cage (21) is protruded from lower body (2) and has air bleeding
inlet (211). A ball (B) is placed in air bleeding inlet (211) and moves along the center of air bleeding inlet (211).
Upper body (3) comprises upper cage (31), air bleeding outlet (311) and extension (32). Upper cage (31) is protruded from upper body (3) and has air bleeding outlet (311). The ball (B) is placed in air bleeding outlet (311) and moves along the center of air bleeding outlet (311).
Guide of lower body (22) provide a correct installation of the lower body (2) and upper body (3) to each other by corresponding the extension of upper body (32). Guide (22) which has a hollowed structure and provides that lower cage (21) and upper cage (31) are aligned on an axis.
There is a ball (B) encaged and a thermal actuator mechanism assembled inside of the space between lower body (2) and upper body (3). Guide for thermal actuator pin is also assembled inside of this space.
In an embodiment of the invention, lower body (2) and upper body (3) which have a suitable geometry to guide the thermal actuator mechanism.
In an embodiment of the invention, preferably wax compound based thermal actuator mechanism is used, which controls the flow of the coolant fluid by means of its movement which is transferred via the thermal actuator pin and which is assembled inside of the space created by the assembly of the lower body (2) and the upper body (3).
Upper body (3) comprises an upper cage (31) which overlaps with the lower cage (21). This overlap is provided by the mounting of the guide (22) and extension (32) to each other. Extension (32) which fits the guide (22) to provide that lower cage (21) and upper cage (31) are assembled on an axis.
A cage in which the ball (B) enclosed inside, is created by means of the overlap. In this way a self air bleeding valve is implemented. The ball (B) which is enclosed inside of the cage mechanism controls the air bleeding by means of whether flow of the air collapsed in the engine or the coolant
pressure of the coolant fluid. In case there is air in the coolant circuit, the air flows through the cage mechanism from the air bleeding inlet (211) to air bleeding outlet (311). The ball (B) is not able to obstruct the flow because of the force generated by this flow.
In case collapsed air in the coolant circuit is fully discharged, the space between the lower cage (21) and upper cage (31) is filled with coolant fluid. Thus a force is applied to the ball (B) which is generated by the coolant pressure of the coolant fluid. By means of this force, the ball (3) moves upward until it seals the air bleeding outlet (311). When the ball (B) seals the air bleeding outlet (311) the fluid is obstructed by the ball (B). So that leakage of the coolant fluid is prevented.
In one embodiment of this invention, lower body (2) and upper body (3) are assembled to
each other by welding or using fasteners.
In one embodiment of this invention, lower body (2), upper body (3) and the ball (B) are
produced by plastic, steel, metal alloy or composite material.
