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 8):
A low pressure regulator as claimed in  claim 5  wherein when the piston is at a certain position between the closed positon and the fully open position, each discharge port hole is not blocked by the outer wall of the piston, and each further damping orifice is not blocked by the outer wall of the piston.
