ABSTRACT:
A pumping system is provided in which a low pressure metering pump injects fluid charges into a high pressure pump which in turn operates into a high pressure load. The high pressure pump is designed to always present a low pressure at its input on its intake stroke. This insures that the metering pump will always operate into a low pressure regardless of the load, and will therefore be enabled to always accurately meter charges into the high pressure pump.
In various embodiments, the high pressure pump and/or the low pressure pump include spring elements for providing well defined pumping pressures.
In some embodiments, an oil reservoir and diaphragm provide a well defined pressure against which the metering pump can operate.
