ELECTROLYTIC CAPACITOR, POWER SUPPLY DEVICE, AND LIQUID FUEL INJECTION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To prevent white smoke and abnormal odor which are generated by an overvoltage from being discharged outside in an electrolytic capacitor. SOLUTION: The electrolytic capacitor 300 is equipped with an interior airtight means 380 for airtightly sealing capacitance element 320 in order to suppress evaporation of electrolyte in regular busy condition, a valve means 370 for discharging gas generated from the electrolyte, from interior of the interior airtight means 380 to outside when the pressure inside the interior airtight means 380 exceeds a threshold value, and an exterior airtight means 400 covering airtightly the valve means 370 in order to accommodate the gas discharged from the valve means 370 to outside.
