Title:
TEMPERATURE SENSITIVE TYPE VALVE MECHANISM
Document Type and Number:
Japanese Patent JP2017187014
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a low-cost temperature sensitive type valve mechanism capable of having thermal performance confirmed.SOLUTION: A pump housing 14 is provided with a main oil path 15, and a return oil path 16 is provided substantially in parallel with the main oil path 15. In addition, a valve insertion hole 17 whose tip almost reaches the return oil path 16 is provided to the pump housing 14 across the main oil path 15. The valve insertion hole 17 has a hole opening provided with a female screw 18, and a through hole 19 extending to outside the pump housing 14 is provided nearby the tip. A temperature sensitive type valve mechanism 20 can be inserted into the valve insertion hole 17 at any time.EFFECT: The temperature sensitive type valve mechanism needs to be carried in a liquid tank or thermostatic chamber together with the pump housing before, the present invention eliminates the need, and the temperature sensitive type valve mechanism which is compact and lightweight is only carried in the liquid tank or thermostatic chamber. Consequently, there is provided the low-cost temperature sensitive type valve mechanism that can have thermal performance confirmed.SELECTED DRAWING: Figure 1
