CASE STRUCTURE OF THERMOSTAT

摘要

The present invention provides a structure of a thermostat case which enables an efficient layout of a liquid flow path by burying the thermostat to a mount member such as an engine head or the like, and also enables to mount the thermostat easily and furthermore enables to place a liquid temperature sensor and a jiggle valve or the like by making the best use of the thermostat case. This structure of the thermostat case is composed of a cylindrical case formed with an entrance opening and an exit opening in a peripheral surface thereof, a flow path area defined within said cylindrical case (1) to bring said entrance opening (1a) and said exit opening (1b) into communication with each other, a valve element (2) moving back and forth across said flow path area in response to a temperature change of a liquid coolant which flows in said flow path area to provide blockage and communication thereof by opening and closing said entrance opening and said exit opening with its movement and a thermostat which is buried into the insertion hole of the member provided with a liquid coolant flow path, wherein a bore (1d) is formed in said case (1).
