CONTROL VALVE ASSEMBLY

The invention relates to a control valve arrangement of an injector, comprising a sleeve-shaped anchor closing body (8) which is axially displaceably arranged on an anchor bolt (13), whose first end face (19) is supported on a stationary holding plate (20), and whose second end face (18) is subjected to high pressure in phases during operation of the injector. According to the invention, a control valve arrangement is specified which is improved with respect to its durability. This is achieved by forming a fluid space (22), preferably designed as a lubrication pocket (23), in the region between the first end face (19) of the anchor bolt (13) and the holding plate (20). In a preferred embodiment, the fluid space (22) is connected via a through channel (21) to the second end face (18) of the anchor bolt. Since pressurized fluid is present at the second end face (18) under high pressure, a hydrostatic bearing of the anchor bolt (13) is thus formed at the first end face (19) relative to the holding plate (20).
