    Hi Friends,

    Would it be possible tell me what is this part inside of white circle and inside of BITZER semi-hermetic compressor ?

    Sincerely yours.

    It’s a Venturi type device to remove oil from the motor housing back into the sump

    I didn't realize my link did not show correct information of part 86 & 103

    Venturi, I'm not sure about that, as would it not pressurize sump, has to use discharge pressure to make venturi work I would have thought!

    Dear RANGER1,
    Thanks for your reply. I found my question answer, It is "EDUCTOR", With this mechanism compressor sucks oil that collected in end of compressor and takes it to sump.
    Photo of educator and how it works at below :

    In this situation with eductor, do you know where the pressure comes from to make it work on input port?
    Sump must be very “open” or large equalisation port to suction of compressor as not to pressurise sump.
    Learn something new every day, hopefully
