Abstract

PURPOSE:To increase a life of a solenoid valve decreased in its cost and weight while enabling leak gas to be collected by circulating oil in the solenoid valve and collecting the leak gas from the circulating oil. CONSTITUTION:Oil is supplied from an oil pump, advancing into an oil supply port 36 of a solenoid valve-provided gas injection nozzle 1, and the oil is allowed to flow in an oil outlet port 22 via oil passages 26, 21, circulating in an oil tank. Consequently, a coil 16 and a yoke 15 are cooled by the oil while well lubricating each sliding member in the solenoid valve. While high pressure gas from a gas supply passage 35 leaks to an upper part housing 11 from a bottom part housing 12 via a clearance between a valve 29 and a supporting unit 30, but this leakage gas is circulated with the oil in the oil tank, separated here from the oil, collected and again used.
