I have downloaded this from some website.PS, can you show me the compressor design?
Its from some old DIY book. I don't think I am allowed to post material here that may be copyrighted or generally downloaded from some dubious sites.
Its very simple reciprocating design with ball valve for delivery side and inlet valve on piston itself.
That's a good idea. I would try and find some fridge or AC compressor.I have an ex-fridge compressor I have been using since the 1970s.
