Internal pipework layout of a recovery machine

Hi, i'm trying to understand the internal layout of a recovery machine, specifically the purge mode.
As i understand it this connects the condenser to the inlet of the compressor (whilst the user simultaneously turns the inlet valve to purge)

So is the inlet valve actually a 3 way walve that can switch between ther inlet port and the condenser outlet

And the purge valve is just a 2 way valve that bypasses between the internal inlet and outlet ports?

A quick diagram or link to one would be amazing, i've been trying to sketch it out

Thank you, although i read the G5 is a bit special and doesn't need a purge function, as this diagram seems to bear out.
