Thats so cool! Just going through some of my old college notes when I was a kid and found his name in there as the inventor of the Roosa Master pump.....genius for sure! A proud grandson no doubt. Thanks
*@Adrossi85* Thank You very very much for uploading this original 8mm (or 16mm) training film. Real training in injection pump repair is accomplished by hands-on disassembly, inspection, re-assembly & dynamic testing machine evaluations, of course... But its of essential benefit to learn the internal components & their functions. Best of all this original film adds to the historic perspective & appreciation for Vernon Roosa's painstaking design & development of his invention. Although Rudolph Diesel built the first single piston type injection pump for the first single-cylinder diesel engine, Vernon Roosa is credited with originating the first rotary type high pressure (2500 to 3500 psi ! !) injection pump And if I understand correctly, Mr Roosa licensed his design to Charles A Vandervell, founder of CAV/ Lucas Injection Company in England ;o)
This is an interesting trip down Memory Lane. I started in the repair business back in '71 and that film was shot in '78. It used to be a really small world as the service schools were all held in Hartford. I knew that instructor and a couple of the students in that classroom scene. Hard to believe that it's been almost 40 years since the film was made....
The DPA is built under license from Stanadyne (Roosa Master). It is based on the Model A pump, the first design from Roosa Master. On earlier DPA pumps there was a reference on the tag saying that it was a licensed product from HMS (Hartford Machine Screw) which is now Stanadyne. Interesting enough, Bosch also licensed the 'Opposed Plunger' principle on its VP-30 and VP-44 pumps.
