Accurate and reliable by a simple thermostat bonding structure. In the thermostate mounting structure, the housing (20) is provided with the coolant inlet (26), the thermal chamber (25) is provided. Formations in order to extend the cross-section with the refrigerant inlet (26), and the thermostats (50) are installed in the thermostats ( 25) The thermostats (50) consist of a cylindrical tongue (51) provided with an inlet (52) and an outlet (53) in the lateral wall of the tongue body. Inlet openings (52) and outlet openings (53) enter into the refrigerant inlet (26). The valve part (61) is installed as a slide. In the body, tongue In order to open and close the inlet opening (52) and the outlet opening (53), the cover (30) has been attached to the housing (20) in order to close the thermostat chamber (25). A) cover (30) has been prepared. It is equipped with a ring groove (34) and an annular seal (40) installed in the ring groove (34) in order to block the leakage of the thermal chamber (25) and to Anchor the thermostats (50) in place. Thermostats (25), flexible seal (40), have an inner corner formed by an annular lip (42) and of an annular spine (43), an annular lip (42), and The circular ridged edge (43) was pressed against the annular end surface (51a) and oblique cut surface (51c) of the tongue body (51) in order to align. The thermostats (50) are positioned precisely and reliably. The thermostats (50) are integrated into the thermostats positioned in the refrigerant compartment. Of the cooling system of the internal combustion engine In order to regulate the refrigerant flow In accordance with the coolant temperature, the thermostat (50) is precisely and reliably positioned by a simple thermostate bonding structure. In the thermostate mounting structure, the housing (20) is provided with the coolant inlet (26), the thermal chamber (25) is provided. Formations in order to extend the cross-section with the refrigerant inlet (26), and the thermostats (50) are installed in the thermostats ( 25) The thermostats (50) consist of a provided cylindrical tongue (51) with inlet (52) and outlet (53) located in the lateral wall of the valve body. The inlet (52) and the outlet (53) go into the refrigerant inlet (26). The valve part (61) is installed in a slid in the valve body to open and Close the inlet (52) and open (53) opening (53) .The cover (30) is attached to the housing (20) in order to close it. The thermostat chamber (25), the cover (30) has been provided with a ring groove (34) and an annular rubber seal (40) has been installed in a ring groove (34) to To block the leakage of the thermostats (25) and to hold the thermostats (50) in place in the thermostats (25). The elastic leak (40) has an inner corner part formed by an annular lip (42) and an annular ridge (43), a ring-shaped lip (42) and a circular ridge (43) are pressed. With the annular end surface (51a) and oblique cut surface (51c) of the tongue body (51) in order to accurately and reliably position the thermostat (50).

Claims (3)

1. A thermostate bonding structure, where: a thermostate chamber (25) is provided in the housing (20) in order to extend the cross-section against the inlet. Of the refrigerant (26), which is formed through the housing (20); The thermostats (50) are installed in the thermostats. (25) Such thermostats (50) consist of a cylindrical body (51) with an inlet (52) and an outlet (53) in the lateral wall of the tongue, and Tongue piece (61) provided in the body, tongue (51), in order to open and close the inlet (52) and the flap (53); The cover (30) is attached to the housing (20) so that the thermostat chamber (25) is closed, such a cover (30) has a rubber ring seal (40) is attached. It is located in the ring groove (34) of the cover to prevent leakage of the thermostat chamber (25) and to hold the thermostat (50) in place in the chamber. Thermostats (25); Its characteristic is that the rubber seal (40) is provided with a ring-shaped shoulder.
