Two-way rotary feedthrough for feeding two fluids from fixed machine section to rotating shaft with axial channel and parallel, eccentric channel connecting with radial bore has two sealing rings mounted near junction of bore and channel

摘要

The two-way rotary feedthrough for separately feeding two different fluids from a fixed machine section (1) to a rotating shaft (2) with an axial channel (3) and a second, eccentric, parallel channel (4) which connects with a radial bore (15) in the fixed machine section. A pair of sealing rings (5) seals the end of the axial channel and a second pair (7) seals the shaft near the inner end of the eccentric channel. A third pair of rings (6) is mounted near the junction of the radial channel and the eccentric channel.
