System comprising a pumping assembly operably connected to a valve actuation source or valve train component

摘要

A system for supplying hydraulic fluid into an internal combustion engine includes a pumping assembly disposed within the housing and a hydraulic circuit operably connected to the pumping assembly and disposed within the housing, the housing comprising: It can be fixed or dynamic. A source of pumping motion is operably connected to the pumping assembly, and the source of pumping motion may comprise a valve actuation source or a valve train component between the valve actuation source and the engine valve. The pumping motion applied to the pumping assembly by the source of the pumping motion causes hydraulic fluid received from the supply pressure hydraulic fluid input of the hydraulic circuit to be sent to the boosted hydraulic fluid output of the hydraulic circuit.
