This holding ring 2 has a notch on its outer periphery, and an elastic seal ring 11 is disposed within this notch. The presser ring 2 is pressed by a wave-shaped ring spring 12 supported by a clamping ring 13 at its crimp surface against a pressing surface extending perpendicularly to the pump shaft 8 at the notch 10', thereby causing the sealing ring 11 to press against the pressing surface. is crimped to. The hold-down ring 2 is filled with fluid and is connected via a passage 16 to the suction side of the pump. A metal support ring 17 is fixed to the pump shaft 8 within the interior chamber 15 . This support ring 17 is supported on the front surface of the inner chamber 15 via an intermediate plate, which is a sliding plate 18. The spring 19 is supported at one end by the support ring 17 and at the other end by the pressure ring 2.
1 is supported by a pin 20 directed outward. This spring 19 acts via a seal ring 22 on a sliding seal ring 23 made of carbon. 1 imitation 12 is spring 1
It has the strength of suffering of 1 in 9.
