Abstract
PURPOSE: To maintain least lowering of a piston body by the self weight by using the synthetic resin made piston ring having tapered guiding surface.
CONSTITUTION: When a pump is stopped with a piston 5 in the extended state of the whole cyle, the pressurized working oil below the piston 5 leaks-out gradually and returns to a tank through an unload hole 3, and the lower edge of the cylindrical surface part X of a synthetic resin made piston ring 9 coincides with the lower edge of the hole 3. At this time, the flexible piston ring 9 begins to be closely contacted onto the inner surface part of the cylinder body 1, so the leak of the pressurized working oil reduces to the minimum. At this time, as this synthetic resin made piston ring 9 has the tapered guiding surface part Y formed on the outer diameter part, the piston ring 9 can penetrate into the inner diameter surface of the said guiding surface part easily, and the piston ring 9 is prevented from being pushed-out into the unload hole 3. Therefore, even if the piston body 1 is switched to descend by a change-over, such a trouble that the piston ring 9 is cutaway is not generated.
