To use this symbol, the p-points must be arranged as shown in the following diagram:
Note:
That P3 is used only for orientation purposes and will have its bore unset. The horizontal offset may be zero; i.e. P0 and P1(and similarly P2 and P3) may be coincident.
5.
Generic type FILT has a connection reference to facilitate connections to reducers.
If the connection facility is not being used, then an eccentric reducer will have a p-arrive, a p-leave, and a P3 to orientate the flat side.
If the connection facility is to be used, P3 will be the connection p-point and as such must have valid bore and orientation data for the connection. As the flat side can be either in the same direction as the connection or directly opposite, a P9 p-point must be used to give the orientation of the flat side.
