にも給油可能となつている。 Furthermore, a pressurizing cylinder 19 for pressurizing lubricating oil containing a piston 18 is arranged in parallel, and a high-pressure liquid introduction member 9 and a high-pressure liquid supply source (not shown) are arranged in parallel.
An oil chamber 20 connected to a lubricating oil supply source (not shown) of the pressurizing cylinder 19 is connected to the sliding portion of the rotating shaft 1 by an oil supply flange 21. A suitable number of grooves 22 are formed on the circumferential surface between the packing 10 of the sliding part of the rotating shaft 1 and the inlet 5, and these grooves 22
It is also possible to refuel.

１の回転は円滑に行なわれる。 The high-pressure liquid passes through the pressurizing chamber 23 of the pressurizing cylinder 19, is guided from the high-pressure liquid inlet 9 into the rotating shaft 1 through the hole 6 of the sealing member 7, passes through the through hole 2, and then enters the outlet 16. flows out from. that time,
The lubricating oil in the oil chamber 20 is pressurized to almost the same pressure as the high-pressure liquid by the high-pressure liquid passing through the pressurizing chamber 23 of the pressurizing cylinder 19, and the sliding area between the inlet 5 of the rotating shaft 1 and the packing 10 is The moving parts are supplied with lubricating oil pressurized to almost the same pressure as the high-pressure liquid by the pressurizing cylinder 19 using the high-pressure liquid as a pressure source.
As a result, the lubricating oil is retained, and rotation of the rotating shaft 1 is performed smoothly.
