Document Type and Number:
Japanese Patent JP2002523670
Kind Code:
A
Abstract:
A control unit for controlling a pressure buildup by a pump unit in a fuel injection system. The control unit has a control valve and a valve actuation unit connected to the control valve. The control valve is embodied as an inlet valve that opens inward in the flow direction. The control unit has a valve body that is supported so that the valve body moves axially in a housing of the control unit and rests against a valve seat of the control valve from the inside when the control valve is closed. In order to give the through flow curve of the control valve as flat a course as possible with small strokes (Ssmall) of the control valve. The control unit includes a throttle device that throttles the flow through the control valve when the control valve is open by a small stroke (Ssmall).
