Method of sealing the rod of a piston moving to and fro, especially in the Stirling engine, and the device for sealing the rod of a piston moving to and fro, especially in the Stirling engine.

摘要

1. The method of sealing the rod of a piston moving to and fro, especially in Stirling engines, consists in implementing mechanical sealing in the form of a gland equipped with sealing rings and skimming rings. Unique characteristics: In the gland chamber, the piston rod (2) is surrounded with the element (6) made of an oil-absorbing material. The circumference of the element is pressed to the rod surface, which ensures constant contact between the surfaces. Once the oil-absorbing element is soaked with oil, it is replaced with a new one. 2.

The device for sealing the rod of a piston moving to and fro, especially in the Stirling engine, consists of a gland equipped with sealing rings and skimming rings. Unique characteristics: The ring (6) made of an oil-absorbing material is axially positioned in the housing of the gland (1) and surrounds the piston rod (2). The ring-shaped clamping elements (7, 8) are mounted around the external circumferential surface of the ring.
