摘要： A reciprocable piston comprises a cylindrical body reciprocable within a hollow cylinder and at least two spaced ring seals disposed around the circumference of the cylindrical body. Within the cylindrical body there is a scavenging system that comprises: an internal chamber that is in fluid communication with a space between the spaced ring seals; and a one-way fluid passage that allows one-way fluid flow from the internal chamber to the cylinder chamber when fluid pressure within the internal chamber is greater than fluid pressure within the cylinder chamber. A method of scavenging fluid comprises collecting fluid that leaks by a piston seal and returning the collected fluid to the cylinder chamber from which it originated, through a scavenging system disposed within the piston.

摘要： A storage tank defines a cryogen space for storing a cryogenic liquid. The storage tank comprises a combined fill and vent assembly, which comprises a conduit having a first end with an opening disposed within an upper part of the cryogen space, and a second end outside of the cryogen space that is connected to a receptacle, to which a re-filling nozzle can be attached. A check valve disposed in the conduit allows flow only in the direction of filling the cryogen space with cryogenic liquid from the receptacle. A by-pass line is provided around the check valve with a valve disposed in the by-pass line that is operable to open or close to control flow through the by-pass line. The method comprises attaching a re-filling nozzle to the receptacle and opening the by-pass valve to vent vapor from the cryogen space to reduce vapor pressure therein and to cool the conduit, receptacle, re-filling nozzle, and fill line. After venting the storage tank, the by-pass valve is closed, and the storage tank can be re-filled through the receptacle and conduit.

摘要： A pilot fuel injection valve is mountable in a cylinder head of an engine and injects a liquid pilot fuel directly into a combustion chamber. The pilot fuel injection valve comprises a cooling system to keep the pilot fuel at a temperature that is lower than the lowest initial boiling point for the pilot fuel that occurs inside the fuel injection valve. The pilot fuel injection valve further comprises a thermally insulated nozzle having an outer surface that is not cooled by the cooler cylinder head and the cooler pilot fuel held inside the fuel injection valve. During operation, the nozzle's outer surface can be heated to a temperature that is not significantly lower than the final boiling point of the pilot fuel so that a significant amount of pilot fuel does not condense on the nozzle surface during engine operation.
