Claims

[Claims for Utility Model Registration] 1. A valve chamber 6 of a thermostat 5 is formed in a hot water channel 4 connecting a water jacket 2 of a cooling engine 1 and a radiator 3, and a valve chamber 6 is formed on the side of the valve chamber 6. A partition in which a communicating valve operating chamber 7 is provided, and a valve body 8 is slidably provided within the valve chamber 6 between a closed position where the warm water channel 4 is shut off and a valve open position where the valve enters and exits the valve operating chamber 7. A temperature-sensitive actuator 9 is provided, which is composed of a valve and displaces the valve body 8 between a valve-closing position and a valve-open position in response to the temperature of hot water flowing into the valve operation chamber 7 from the hot water channel 4. A cold water engine thermostat featuring: 2. In the structure according to claim 1, a butterfly valve 18 is used as the valve body of the thermostat 15 in place of the gate valve 8, and the butterfly valve 18 shuts off the hot water channel 4 within the valve chamber 6. A thermostat for a water-cooled engine, characterized in that it is swingable between a valve closed position and a valve open position along the axial direction of a hot water channel 4. 3. In the structure according to claim 1, a plug-shaped valve 28 is used as the valve body of the thermostat 25 in place of the gate valve 8, and the plug-shaped valve 28 crosses the hot water channel 4 within the valve chamber 6. The plug-shaped valve 28 is provided so as to be rotatable about its axis, and the plug-shaped valve 28 is provided in the valve chamber 6 in a direction perpendicular to the rotation axis of the plug-shaped valve 28 .
A thermostat for a water-cooled engine, characterized in that a water passage 28a is formed through the hot water passage 8 and has a passage cross-sectional area that is approximately the same as the passage cross-sectional area of the hot water passage 4.
