Re: [CAD_CAM_EDM_DRO] Bridgeport way wear,lubrication fix

I'm not certain about the Bijur oil pump but most pumps have an exhaust valve that acts as a check valve to prevent the chamber from pulling on the exhaust side during pump stokes. This would prevent the oil from running back out of the system. Most simple pumps like that are just a piston or diaghram in between two spring loaded check valves going the same direction.
