Beschreibung
Zusammenfassung:	A pressure limiting valve 14 (PLV), a common rail 12 assembly and methods of tuning a common rail assembly are disclosed. The pressure limiting valve 14 comprises a body 28 provided with a bore (46, figure 4) with a seat member 41 at an end, surround a spill orifice 50. An adjustable valve assembly 29 comprising a valve member 30, a spring 34 and a plug 36 is arranged in the cavity (46, figure 4). The position of the retainer 36 can be adjusted and may compress the spring against the valve member. The seat 41 may be integral with the body 28 or a separate part. The disclosed fuel reservoir 12 assembly is tuned by pre-assembling the pressure relieving valve 14, fixing it in the common rail and then tuning the PLV to a target safety pressure threshold. The valve may be tuned by tightening or loosening the plug. The PLV and common rail arrangement overcomes weakness issues encountered by valves that are crimped or use shims.
