Small suction line accumulator
I'm trying to locate a small suction line accumulator, as used on a/c rotary compressors. See part in red in sketch below.
If anyone knows where such a device can be purchased separately to the compressor, I'd be most grateful for links & references.

Re: Small suction line accumulator
Are you sure that that is an accumulator?
There is often a muffler in that position.Brian - Newton Abbot, Devon, UK

Re: Small suction line accumulator
Failing that, why not just make one from copper tubing. allowing for an internal riser and some provision for oil return.

Re: Small suction line accumulator
All rotary compressors have an accumulator mounted on the side. That's because the incoming gas goes straight to the suction valves. The crankcase and motor are on the high side.

A few pictures of an experimental set-up, showing the internal construction of these accumulators / particle-smashers:

Re: Small suction line accumulator
You need to make a small opening, slot or hole to allow oil to weep from the lower point back into the riser. The opening needs to allow the oil to return at the same rate it is being recovered of course. Small amounts of refrigerant liquid may pass thru when there is a low oil level, but this should not be a problem generally as the liquid is most likey to boil off before it travels any distance.
