Abstract:
A low pressure regulator for a high pressure fuel pump includes a standard damping orifice, providing a constant level of piston movement damping by enabling a fluid pathway between a spring chamber and a return line. The low pressure regulator also includes a further damping orifice, which is covered by the piston when discharge port holes are open, the further damping orifice providing a further, variable level of piston movement damping by providing a further fluid pathway between the spring chamber and return line. The further damping orifice is open in a hydraulic accumulator mode and closed in a regulator mode, thereby reducing pressure spikes caused by insufficient spring chamber filling.

Claim (Index 6):
A low pressure regulator as claimed in  claim 5  wherein when the piston is at a certain position between the closed position and the fully open position, each discharge port hole, and each further damping orifice, are blocked by the outer wall of the piston.
