Oil pump explanation of Copeland semi-herm

[Peter_1]

Does someone have a manual or explanation about the oil pumps, found on Copeland, the systems where the rotation doesn't matter, the oil pumps always the right direction (the swash/swap plate system with the very small stop pin, on the outer non-rotating housing, set out of the middle of the pump)

They are all the same. Frascold uses the same concept. Unfortunately, there is no exploded view available, as far as I know. You may try downloading the spare part electronic catalogue from frascold's website and see if the detail is high enough for you.
You just need the drawing, right. I'm sure you perfectly know how it works, don't you?

Try searching patents.

Sure, I know but I was trying to find drawing or photo's with the different positions in both directions and the intermediate position while changing direction, perhaps some pictures what happens when the stop pin brakes (this is how I discovered years ago how this pump works)

Peter,

I've looked through all my Copeland stuff and didn't find any internal diagrams of the pump.

There are plenty of pictures of the oil pump in the AE bulletins and manuals that I'm sure you have.

Thansk, this is what I found so far http://www.hvacrinfo.com/cope_ae_bulletins/TAE1166.PDF
