Zusammenfassung:	A drive system (114) for a cryogenic pump (110) is provided including a spool housing (150) having a plurality of valves (240) disposed therein about a pump axis (118) and a tappet housing (152) including a plurality of tappet bores (200), each tappet bore in communication with a respective one of the plurality of valves (240). A collection cavity (220) collects hydraulic fluid from the tappet bores. A pump flange (119) includes a fluid inlet (302) and a fluid outlet (304). An inlet manifold (305) directs hydraulic fluid received through the fluid inlet (302) to each of the plurality of valves (240). An outlet manifold (322) directs hydraulic fluid from each of the valves (240) and the collection cavity (220) to the fluid outlet (304).
