Abstract
An apparatus for gas-tight sealing of the connection points between a stationary machine part and a machine part which is rotationally mounted with respect thereto has an annular disc disposed adjacent to the connection point on one of the machine parts, the annular disc being surrounded by an annular channeled housing which spans the connection point and is mounted on the other of the machine parts. The housing contains at least one washer or packing ring which bears against the annular ring and further includes a structure for applying pressure to the washer to maintain the washer against the ring.
Claims3
An apparatus for gas-tight sealing a connection area between a stationary feed line or exhaust line and an exhaust port of a rotary reaction cylinder rotationally mounted with respect to said feed or exhaust lines comprising:
- an annular disc mounted on the exterior of said exhaust port at an edge thereof adjacent to said connection area;
- an annular channeled housing mounted on said stationary feed or exhaust line spanning said connection area and surrounding said annular disc, said housing having a square U-shaped cross section;
- a pair of washers disposed on opposite sides of said annular ring and adjacent thereto;
- and
- a pair of hollow bellows jackets each having an end thereof connected to an interior wall of said housing and each having an opposite end respectively connected to said washers for supporting said washers in said housing in bearing relation against said annular disc for gas-tight sealing of said connection area.
