Abstract (en)

[origin: JPS6424192A] PURPOSE: To surely seal a work chamber for long hours by forming a spring member arranged between a sealing strip and a groove bottom from a tube made of silicon rubber, relating to a displacement machine for compressible media. CONSTITUTION: On both sides of a disk 4 a displacement body 5 extending spirally is disposed. The displacement body 5 is engaged with the exhaust chamber 6 of a casing 7. On the end face of the displacement body 5 an annular groove 13 is provided and into the groove 13, an elastic sealing strip 14 made of a material possible to slide, is inserted. A spring member 15 is disposed between the sealing strip 14 and the groove bottom. The spring member 15 consists of a tube made of a silicone rubber. Thus, the work chamber can be surely and satisfactorily sealed over long hours of operation.
