Bosch VE,VP pump head demonstration, how it works

in this video ill try to explain the delivery head and plunger of a bosch axial distributor pump
ill also include a little bit of how these are timed
many moons ago before i tore one down i could never really get my head round all of it until i had it in my hand , you can look at diagrams all day but sometimes you just need it in your palm and have a good look over it
