Abstract

PURPOSE: To prevent the provision of such as the air to the lower portion of a piston rod, by providing an enclosure inlet-outlet ports at such position where the operational oil level in an operational oil tank will be as deep as possible.
CONSTITUTION: An enclosure 8 having inlet/outlet ports E is provided at the position in an operational oil tank 7 where the operational oil level will be as deep as possible in the up-down process. Consequently said ports E are placed at the furthermost position from the oil level while since the operational oil in said tank 7 and from a returning tube 6 can be led to the suction port C, thereby the air in the air space of said tank 7 is prevented from mixing with the operational oil and the air can be prevented from being supplied to the lower portion of the piston rod without sacrifice of the pump efficiency.
