Thread: diy silent compressor

how many tubes do your fridge compressor have coming out of it ?

I may be mistaking but I think that the intake tube and the compressor air/oil mist tube were part of the cooling coil /heat exchange /in other words the freon gas and oil were reused over and over, is 1 or both of the bottom tubes ends squeeze together or was they solder close, I am not sure but you might be able to add the oil for the compressor thru. one of the two tubes, DO YOU HAVE a water filter installed on the high pressor side of your compressor to stop the oil mist ?

I cut a hole in the top of the motor to add oil through, so thats not an issue, I was just wondering how you recirculate oil back in if possible as the sil-air compressor I have must do that?? Unless there is a major difference in motors between the two?

COLOR="Red"]the two tubes on the bottom are open still, just cut off...not sure what they are used for originally as i couldnt find info on motors with 4 tubes coming off it. [/

If the bottom tubes are out in the open where you can get to them with your finger tip then turn the compressor on and stick your finger tip over the tube end to see wheter or not you had got compress air coming out of the tubes or a vacuam going in the tubes, if the tube are a vacuam line then add some oil and see what happen

the only way to circulate oil that I see is to separate the oil from the compress air and route the oil back to the intake tube or to a another tube that will permit the oil to enter the compreesor piston area, topping it off every so often and empty the filter of its oil every day will be much simple unless someone with building compressor experience see this post and offer thier advice

I am sure that someone has try it and possible figure the details out, I do not know how you can separete the oil from the compress air but if you can built something to do this then add a air regulation between the separetion and compreesor and set it at about 5psi to keep the oil moving
