Description

The thermostat is mounted in the case of the thermostat, and in the second case it is mounted on the bracket for attaching an additional bulb to the thermostat cap, which is integrated with the socket. FIG. 1 is presented; a schematic diagram of the described device; in fig. 2 - thermostat in longitudinal section. The internal combustion engine 1 is made with a jacket for circulating in it a cooler, in which the first region 2 is located in the cylinder block and covers practically the contact zone between the cylinder e and the pistons, the second region 3 is located in the cylinder head. The shirt covers, in a similar way, combustion chambers and gas exchange channels. For circulation of the cooler through the jacket, inlet 1, 1 of the unit's upper part, the inlet 4 is made, and in the upper part of the head an outlet 5. To the latter, the coolant outlet 6 from the engine is connected, equipped with a branch 7 connected to the thermostat 8. Jumper 9, made in the case of the thermostat, limits the branch cavity provided for placing the main thermo-bottle Y in it. The disc valve 11 attached to this thermo-bottle serves as a branch blocking body, since n to shut off the control holes 12 in the jumper 9. The thermostat is connected to the radiator 14 at its lowest point 15 by means of a nozzle 13. In addition, a coolant supply pipe 16 to the engine is connected to the thermostat housing by means of a pump 17, the discharge pipe 18 of which connected to the opening 4 shirts. At the junction of the pipeline 16 with the thermostat, a duct 19 is formed in the latter, communicated by means of an aperture 20 with a compartment 21 provided in the thermostat's housing, acting as a radiator bypass pipe, and additionally communicated with a nozzle 13 by means of openings 22 in the bridge 23 An additional thermal bulb 24 is attached to this jumper, to which are two poppet valves 25 and 26 connected, alternately blocking either the control holes 22 in the jumper 23 or the hole 20. Valves assembled with a thermal balloon function as the organ of connecting the channel alternately to the branch and to the nozzle. The design of the thermostat shown in FIG. 2, corresponds to its concept, discussed above. A cover 28 is attached to the housing 27, which is mainly cast from aluminum or light alloys. A sealing gasket 29 is installed in the junction between them. To fasten the housing on the engine, it is equipped with races 30. The cavity of the cover is a continuation of the radiator connection pipe 13 to the thermostat, those. The valve is actually combined with the nozzle. A through duct 31 is made in the housing, which is a section of the main 6 of the coolant outlet from the engine. In the branch 7 of this line is located the main bulb 10. In the case of the thermostat is placed an insert 32, made in the form of a glass, inside which is located channel 19. The bottom of the glass serves as the seat of the poppet valve 26. A jumper 9 is clamped between the bottom of the glass and the case A sealing ring 33 is provided with the body. The main and additional thermocylinders and valves attached to them are located along one common axis. An additional thermal bulb 24 is supported through a piston rod 34 on a bracket, which is combined into one unit with a jumper 23 fixed in the junction between the housing and the cover. When the temperature rises, the expansion of the additional thermal bulb is possible only towards the bottom of the glass 32. With sgom located on the additional thermal 5a, the disc valve 25 moves away from the cotia made in the jumper bracket securing the additional thermal bulb to the lid and informs (using holes 22 and channel 35 ) channel 19 with a radiator pipe, and disc valve 26 sits on the seat 36, blocking the opening 20, and thereby disconnects channel 19 from compartment 21, which serves as a radiator bypass pipe, and from branch 7. Wuxi tion of thermal expansion of the bulb is directed against the spring force 37, resulting in a low-temperature coolant spring provides reliable valve land 25 on its seat. The poppet valve 26 is fixed on the protrusion of the additional thermal bulb and fixed axially with the help of a retaining ring 38. To ensure that this valve fits snugly to the bottom of the glass, a spring 39 is provided that rests on the shoulder of the additional thermal balloon. The valve seat 26 may be formed either by the bottom of the glass, or otherwise formed in the body. The design of the branch blocking organ is similar to that of the channel connecting organ structure discussed above, alternately to the branch and the branch pipe. The main bulb is supported by the piston rod 40 on the thrust collar 41. As a result, the disc valve 11 retracts from its seat, made in bridge 9, when expanding the thermal cylinder, breaking the force of the spring 42J resting on the stop bracket 43 attached to the jumper 9. In addition to the elements listed above, The device shown in FIG. 5 of the design, there is an auxiliary channel 44 used in the case of combining the engine cooling system with the heating system of the vehicle on which it is installed. After starting the engine, when the cooler is not sufficiently heated, the springs 37 and 42 press the poppet valves 11 and 25 to the seats. As a result, the flow sections of the branch and the nozzle are blocked. The heat carrier enclosed in the jacket and radiator is the possibility of circulating through any closed circuit through the coolant supply pipe 16 to the engine. In this case, heat is removed from the engine only as a result of the thermosiphon circulation of the cooler in the jacket. Naturally, the heat removal is not so intense, which contributes to increasing the temperature of the working surfaces of the engine combustion chamber and improving the flow of the working process. This warm-up period can be called the first warm-up phase. In addition, the presence of this phase accelerates the heating of the cooler in the engine jacket and, due to the increase in temperature of the walls of the combustion chamber, improves the starting and reduces the amount of harmful components in the exhaust gases.
As the cooler warms up due to expansion of the main thermal bulb, the branch shut-off organ opens and the cooler is allowed to circulate through the jacket and radiator by-pass.
This part of the process is the normal warm up phase of the internal combustion engines. As a result of excluding the radiator from the circulation circuit, the engine is warming up in this phase quite intensively. In the process of increasing the temperature of the cooler in its circulation loop through the jacket, its temperature rises both in the radiator and in the socket 13. The additional thermal bulb expands, the valve 25 opens and communicates the socket 13 with the coolant supply pipe 16 to the engine, and the valve 26 closes the opening 20 bypass pipe, reducing the flow of coolant from it. Due to the fact that the additional thermal bulb is placed in the nozzle, the temperature in which rises only as a result of the thermosiphon effect, the opening of the valve 25 occurs at a sufficiently high temperature of the cooler in the jacket, and therefore the second warm-up phase is reduced. After opening the valve 25, a partial cooling of the cooler in the radiator and its partial passage through the bypass pipe take place, followed by mixing in the channel 19 of the thermostat.
After reaching the operating temperature, the valve 26 completely blocks the access of the cooler to the channel 19. The warm-up process ends.
Thus, the described device provides accelerated heating of the system after start-up, and the body connecting the channel in the form of two disc valves placed on a common stem, one of which has a seat installed in the thermostat housing, and the second - on the thermoballder bracket to the thermostat cover , greatly simplifies the design of the latter.
