Thermostat valve for heating and/or cooling body, has omega spring provided for protection of free mobility of plunger and wheel, and working together with extension of wheel when extension approaches end position of housing

摘要

The valve has an intermediate plunger with intermediate plunger parts, which are mounted in a transmission drive gear wheel (6) in a torque proof and axially movable manner. The intermediate plunger parts are connected with each other by a thread. An intermediate part (1) has an omega spring (28) for protection of free mobility of the intermediate plunger and the transmission drive gear wheel. The omega spring works together with an extension (29) of the gear wheel when the extension approaches an end position of a housing (8) by the tension of the spring.
