CASE STRUCTURE FOR THERMOSTAT

摘要

PROBLEM TO BE SOLVED: To provide a case structure for a thermostat allowing efficient layout of a coolant flow passage by burying the thermostat into a member to be mounted such as an engine head, an easy mounting work of the thermostat, an effective use of a case of the thermostat and easy mounting of a liquid temperature sensor and a jiggle valve. SOLUTION: In the case structure comprising a cylindrical case 1 with an inlet opening part and an outlet opening part formed on a peripheral surface, a flow passage area for communicating the inlet opening part 1a and the outlet opening part 1b within the case 1 and a valve element 2 advancing/retreating so as to cross the flow passage area according to a temperature change in coolant flowing in the flow passage area and interrupting and communicating the flow passage area by the advancing/retreating and being buried into a fitting hole of the member to be mounted with a formed coolant flow passage, a through hole 1d is formed in the case 1.
