Metering unit for high-pressure pump, is formed with two valve elements, where metering case has two outlet openings for each valve element, and two valve elements are hydraulically separated

摘要

The metering unit (37) has a valve element (14), a device (16) for moving the valve element in a direction, another device (18) for moving the valve element in another direction, and a metering case (45). The metering unit is formed with two valve elements. The metering case is completely made of plastic or metal, such as steel or aluminum. The metering case has two outlet openings (42) for each valve element. The two valve elements are hydraulically separated. Independent claims are included for the following: (1) a high-pressure pump with a drive shaft; and (2) a high-pressure injection system of an internal combustion engine with a high-pressure rail.
