Vacuum Symbols
All symbols, except those marked
*)
may be used in any orientation.
The symbols for vacuum pumps should
always be so positioned that the narrowing
lines point to the side of higher pressure.
*)
These symbols must only be used in the
indicated position (tip of the triangle pointing
downwards)
