Abstract (en)
A cryogenic pump 2 is typically used to supply high pressure natural gas to an engine. The pump 2 has a piston 6 operable to discharge cryogenic liquid from a pumping chamber 8 within a pump housing 4. The cryogenic liquid exits the chamber 8 through an outlet port 10 in which a check valve 12 is positioned. The check valve 12 has a valve member 14 which is loaded by a spring 28 and is retained by a retaining member 16 accessible from outside the housing 4. The check valve 12 has an inlet 18 which is axial with the valve member 14 and an outlet 20 which is transverse to the axis of the valve member 14.
