      Has anyone any idea how the oil in an Enots oiler arrives in the upper chamber? I've stripped mine down (1924 OK Junior) , all oil ways are clear but the pump will draw oil from the tank when piston is lifted but pumps it back out again when pushed down. How does the oil get to the upper side of the piston? It would appear to operate similarly to a bicycle tyre pump other than there isn't a valve to prevent the oil returning from whence it came. Am I overlooking the obvious?

            Thanks for your assistance Eric, I had seen this on the net; There is a small drilling at the head of the pump for the oil to get out of the upper chamber but I can't fathom how the oil gets into the upper chamber. I've assembled the piston in both directions but no joy. I'll contact the VMCC; they'll probably know, can't be rocket science!

              Hi Vernon

              Having had a bit a think about this Oiler with the pump washer facing upwards there may be one way valve in the discharge to the oil drip feed piping as well as the oil control valve.

              When the top of the top up the pump chamber is filled with oil. Pushing down the plunger will create negative pressure and pull the oil past the pump washer being by restricted-throttled or blocked by the one way valve.

              The spring will maintain the oil supply until it reaches the top of it's stroke.

              Hope this Helps

              Eric

                Methinks that's it Eric; that's the principle; I'll see if I can get a replacement cup washer, it may just solve it altho' the one already on looks ok. Thanks for your input.
