Abstract
A liquid pump applicable in a fuel system such as a common rail fuel system includes a valve assembly having a valve stack with axially aligned components, dead volume, and vapor-distributing flow channels, for cavitation mitigation. An inlet valve meters a flow of liquid into the pump for pressurization by a plurality of reciprocating plungers operated by way of a rotating camshaft.
