The oil will contaminate quickly and it will no longer be dielectric. <DIV>Just the hose from the motor to the tee is enough to compensate. You do not have to have a large volume of oil. Fill the hose with oil and cap it off, done. or make a neat yet more sophisticated solution. </DIV><DIV>Make the end lid of the motor as a flange assembly and instead of a lid, use a rubber diaphragm. This will then act as a compensator. You can even install a light spring pushing down on the diaphragm if you want a slight internal overpressure. </DIV><DIV><DIV><IMG src="cid:20200324151919.C61DED4C@m0117164.ppops.net" alt="image.png" width="552" height="562"><BR></DIV></DIV></DIV><BR><DIV style="font-size: 10pt;"><DIV dir="ltr">tir. 24. mar. 2020 kl. 21:28 skrev Brian Cox via Personal_Submersibles <<A href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</A>>:<BR></DIV><BLOCKQUOTE style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><DIV style="font-family:Arial,sans-serif;font-size:10pt"><FONT size="2">Here is a drawing for my oil compensator</FONT><DIV><FONT size="2"><BR></FONT></DIV><DIV><FONT size="2"><BR></FONT></DIV></DIV>_______________________________________________<BR>
