Abstract (en)
[origin: EP1251266A1] The limiter (56) has a housing (58) with intake (70) and outlet (86), connected by a tensioned element (82) at a set pressure differential. The limiter has a bypass volume, in direction of flow in front of the tensioned element. A hydraulic resistance, esp. a flow throttle (74), is positioned in the intake to the bypass volume, which also contains a pre-chamber (72). The bypass volume is created by movement of the tensioned element. The element is a cylindrical piston (82) with outer and intake-sided sections (94,92). The pressure limiter is pref. integrated in a second fuel pump.
