摘要： A high pressure fuel pump includes a pump housing, pressure and damper chambers, a metal diaphragm, a press-fitted portion, and a weld portion. The pressure chamber is provided in the pump housing. The damper chamber is formed by the pump housing and a damper cover. The metal diaphragm damper is arranged in the damper chamber. At the press-fitted portion, an annular surface of the damper cover is press fitted to an annular surface of the pump housing. The weld portion fixes the damper cover to the pump housing at an entire circumference of the press-fitted portion.

摘要： A mechanism for reducing pressure pulsation includes a pair of metal dampers formed by joining two disk-shaped metal diaphragms over an entire circumference and forming a hermetically sealed space inside a joined portion. Gas is sealed in the aforementioned hermetically sealed space of the damper, and a pair of pressing members give pressing forces to both outer surfaces of the aforementioned metal dampers at a position at an inner diameter side from the joined portion. The mechanism is unitized, with the pair of pressing members being connected in a state in which they sandwich the metal damper.

摘要： A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.
