    摘要： A high pressure fluid system including enhanced safety, maintenance and servicing features. The system can include a CAM assembly module, having a valve seat assembly, seal cartridge assembly and inlet manifold, that is easily installed in and removed from a frame and/discharge manifold as a single unit. A discharge manifold can isolate different pressure rated passageways of the system, and multiple rupture discs associated with the same. A discharge manifold end plate can be included to provide ease of repair of discharge outlets and to establish a plumbing system for the rupture discs. A quick coupler can facilitate connection between a plunger of the seal cartridge assembly and a cross head stub connected to a power frame. A lubrication valve assembly can provide and meter lubrication from a high pressure inlet source to a plunger and packing of the seal cartridge assembly.

    摘要： A high-pressure fuel pump includes a housing and a swash plate which is mounted in the housing and is arranged in an oil space of the housing. A drive shaft is connected to the swash plate and passes through a housing opening, and with a seal for the drive shaft, which seal is mounted in the housing in the region of the housing opening. The high-pressure fuel pump has a plurality of pump elements for sucking up, compressing and ejecting fuel, which pump elements can be acted upon consecutively by the rotatable swash plate. In a pump of this type, the fuel pump has at least one magnet, the magnetic force field of which acts on the oil space of the housing. Premature wear of the pump, in particular premature wear of the seal, is avoided since the magnet separates off iron-containing dirt particles found in the oil.

    摘要： A high pressure fuel pump (20) that pressurizes and supplies a fuel by driving a cam (21) such that a plunger (23) reciprocates, the high pressure fuel pump (20) comprises a lifter guide (25) having a guide hole (25A), a lifter (22) that is disposed between the cam (21) and the plunger (23) and is fitted into the guide hole (25A) to be free to slide so as to transmit a driving force from the cam (21) to the plunger (23), an oil collection portion (27) that is provided above the guide hole (25A) so as to surround a periphery of the lifter (22), and stores a lubricating oil for lubricating a sliding portion between the lifter (22) and the guide hole (25A), and an oil supply passage (25C) for supplying the lubricating oil to the oil collection portion (27). As a result, a reduction in a lubricating performance with regard to the lifter (22) in a position away from an opening portion of the oil supply passage (25C) is suppressed.
