Document Type and Number:
Japanese Patent JP2002531747
Kind Code:
A
Abstract:
A fuel injection pump having a cam drive and an injection adjuster piston, acting on the cam drive and serving the purpose of an injection onset adjustment. The injection adjuster piston on a face end encloses at least one pressure chamber that via a control valve is either made to communicate with a pressure source or a relief line or can be closed entirely. The control valve is actuated by an a proportional electromagnet. As a result, only a little adjusting medium is required, to obtain a high efficiency of the injection onset adjustment, and advantageously the injection adjuster piston is stressed only axially, and frictional forces on the circumference of the injection adjuster piston are thus avoided.
