Why an oil trap should prevent for liquid slugging? It's just the opposite: liquid can accumulate as as soon area is reduced enough, all the liquid is pushed through it at once.
And the trap on a evaporator is only for compressor startup so that oil and liquid dont effect the txv sensor
This is not worth arguing on it because both doesn't have a relation with each other.
Hi Peter1

Not liquid slugging. Slugs of oil.

Marc O'Brien showed us image 19.5 on page 455 in my RJ Dossat. I have the 3rd edition. It shows the txv bulb must be installed 30cm up the vertical riser if a trap cannot be used. If a trap can be used then the bulb can be installed before the trap on a horizontal. The trap collects oil during the off cycle so that it does not interfere with the bulb when the compressor starts.
