The tongue piece (61) is mounted in a sliding motion. in the body of the tongue In order to open and close the inlet opening (52) and exit opening (53), a cover (30) is attached to the housing (20) in order to close the thermostat chamber (25). ) The cover (30) has been provided. An annular seal (34) and an annular seal (40) are installed in the annular groove (34) to prevent leakage of the thermostat chamber (25) and to Hold the thermostat (50) in place in Thermostat chamber (25), flexible seal (40), has an inner corner formed by an annular lip (42) and an annular ridge (43), an annular lip margin (42), and The circular ridge margin (43) is pressed against the annular distal surface (51a) and oblique surface (51c) of the tongue body (51) in order to provide Thermostats (50) are positioned accurately and reliably. Thermostats (50) are integrated into a thermostat unit located in the refrigerant compartment. of the cooling system of the internal combustion engine in order to control the refrigerant flow In accordance with the chiller temperature, the thermostat (50) is positioned precisely and reliably by a simple thermostat mounting structure. In the thermostat mounting structure, the housing (20) is provided with the cooler inlet (26), the thermostat chamber (25) is provided. Formations to extend cross-section to the refrigerant inlet (26), and the thermostat (50) are installed in the thermostat chamber ( 25) Thermostat (50) consists of a cylindrical tongue body (51) provided with an inlet (52) and an outlet (53) located in the side wall of the tongue body. Inlet (52) and outlet (53) open to the refrigerant inlet (26). The tongue piece (61) is mounted in a sliding motion in the tongue body to open and Close the inlet (52) and outlet (53). The cover (30) is attached to the housing (20) in order to close. Thermostat chamber (25), cover (30) is provided with an annular groove (34) and an annular rubber seal (40) is installed in an annular groove (34) to to block the leakage of the thermostat (25) chamber and to hold the thermostat (50) in place in the thermostat (25) chamber. Flexible leak (40) has an inner corner formed by an annular lip margin (42) and an annular ridge margin (43). An annular lip margin (42) and a circular ridge margin (43) are pressed together. with the annular end surface (51a) and oblique cutting surface (51c) of the tongue body (51) in order to position the thermostat (50) precisely and reliably.

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.
