High pressure fuel pump, has throttle arrangement provided at high pressure side of valve seat of pressure limiting valve, where cross section of arrangement is approximately equal to desired maximum opening cross section of valve
摘要
<p>The pump has a high pressure discharge unit (26), and a pressure limiting valve (42) with a valve unit that is actuated by a pressure difference. A throttle arrangement (64) is provided at a high pressure side of a valve seat (54) of the pressure limiting valve. The cross section of the throttle arrangement is approximately equal to a desired maximum opening cross section of the pressure limiting valve.</p>
