摘要： A system for supplying hydraulic fluid in an internal combustion engine comprises a pumping assembly disposed within a housing and a hydraulic circuit, operatively connected to the pumping assembly, also disposed within the housing, which housing may be fixed or dynamic. A source of pumping motions is operatively connected to the pumping assembly, which source of pumping motions may comprise a valve actuation motion source or a component of a valve train between the valve actuation motion source and an engine valve. Pumping motions applied to the pumping assembly by the source of pumping motions causes hydraulic fluid received from a supply pressure hydraulic fluid input of the hydraulic circuit to be transmitted to an increased pressure hydraulic fluid output of the hydraulic circuit.
