Abstract: A fuel pump comprises a housing with a pumping chamber, an outlet passage and a pumping plunger which is reciprocally arranged within a plunger bore. A pressure relief valve assembly is arranged in a pressure relief passage and includes: a seat member comprising a through bore extending from a first side to an opposite, second side, and an annular seat in the second side surrounding the bore, wherein the seat member is arranged in the pressure relief passage with the first side exposed to high pressure; a needle having an elongate shaft with a needle head, which extends through bore, the needle head being proximal the seat member and having an annular seat surface adapted to cooperate with the annular seat to close the through bore in a closed position; and a spring element arranged to exert a closing force on the needle such that it is biased in closed position.

Abstract: A radial adsorber comprising: an adsorbent mass containing particles, a cylindrical shell ring extending along a longitudinal axis that is vertical when the adsorber is in operation, an external grid and an internal grid arranged in such a way as to be permeable to the gas and impermeable to the particles, the internal grid and external grid between them forming an annular volume housing the adsorbent mass, an internal chamber located between the vertical longitudinal axis and the internal grid, an external chamber located between the external grid and the shell ring, the internal chamber and external chamber being intended for the circulation of the gas, the external grid being formed by a plurality of wires and a plurality of supports, the supports being mounted transversely to the wires, the supports and the wires being mounted secured to one another.

Abstract: A process for producing a purified gas stream having impurities, using a production unit for producing a gas stream and a storage reservoir. The process includes producing a first gas stream by means of the production unit. Storing at least a portion of the first gas stream in the storage reservoir. Extracting, from the storage reservoir, a second gas stream corresponding to at least one portion of the first stream polluted by the impurities. Purifying the second gas stream by transfer of at least one portion of the impurities contained in the second gas stream into the first gas stream. And recovery of the purified gas stream at the output of the purification.

Abstract: Process for conditioning a container including a granular material A enabling the adsorption of the nitrogen contained in a feed gas stream, including a step of injecting, into the container, a gas or a gas mixture G such that the adsorption capacity of the material A with respect to G is less than 10 Ncm3/g at 25° C. and 1 atm.

Abstract: A process for establishing vacuum insulation under cryogenic condition and an apparatus compatible with such process are described. When an insulation enclosure filled with high purity CO2 is evacuated to around 100 absolute Pa at ambient temperature, hard vacuum of below 1 absolute Pa may be automatically obtained within the insulation enclosure when temperature drops to around or below ?170° C. This process can be employed to provide vacuum insulation for cold box housing air separation units operated under cryogenic condition.
