ELECTROMAGNETICALLY CONTROLLED VALVE FOR A HIGH PRESSURE PUMP AND HIGH PRESSURE PUMP

摘要

The invention relates to a electromagnetically controlled valve for regulating the delivery of a high pressure pump in a fuel injection system, comprising a valve piston (1) which can be axially displaced by the piston guide (2). According to the invention, the valve piston (1) comprises an at least partially structured outer peripheral surface (3) for improving the lubrication and/or for reducing the friction between the piston guide (2) and the valve piston (1). The invention also relates to a high pressure pump for a fuel injection system comprising said type of valve.
