Abstract
PURPOSE: To prevent gas from leaking to distance pieces, by filling the same gas in a distance piece provided with a shaft seal part and by making the pressure of the gas in the distance piece higher than that of the gas in the other adjacent distance pieces.
CONSTITUTION: An upper distance piece 1, an intermediate distance piece 2 and a lower distance piece 3 are provided between a cylinder 4 and a crankcase 5. The intermediate distance piece 2 is provided with a shaft seal part 20 hermetically filled with oil 201 for sealing-up. The opening and closing of a solenoid valve 72 for gas supplied from a pressure tank 73 is regulated by a differential pressure detection controller 71 to make the pressure in the distance piece 2 slightly higher than that in the distance piece 1.
