摘要： The invention relates to a method and an injector for determining a position of a second part (10) inside a stepped boring (6). This part should assume an exact distance (H) from a first part (2). In order to determine the distance (H) between both parts (2, 10), a collar (3) is firstly introduced into a second boring (6b) of the stepped boring (6) until it rests upon a step (16) of the stepped boring (6). Afterwards, a punch (4), together with a touch probe (5), which is located inside a longitudinal boring (d), is placed upon a lower annular surface (17) of the collar (3) or on an underside (17a) of the first part (2), and the collar (3) is compressed until the predetermined distance (H) is obtained. The distance (H) is measured to a reference measure (x) between a projecting end piece (E) of the touch probe (5) and a reference mark (B) outside of the punch (4). The stamping process is stopped once the reference measure (x) has been obtained.

The fuel injector further comprises a nozzle body, with a top surface on which the control module is mounted. The nozzle body comprises a drilling with a nozzle needle, co-operating with the control piston, arranged in the lower section thereof and the piston guide, arranged in the upper section thereof.

摘要： A transfer device for transferring an actuator displacement, has a housing with a first recess having a first and second plunger displaceably mounted. These plungers are actively connected via at least one transfer chamber by a fluid. The active connection causes the second plunger to be displaced when the first plunger is moved and vice versa. The transfer chamber is hydraulically coupled via a sealing gap to a compensating chamber compensating the pressure differences, in a delayed manner. The transfer device also has a chamber device with a compensating chamber, a chamber housing, and a first plunger. The chamber device has a device with a first body with a recess including a second body, and with an elastomer placed in the recess between the first and second body. The elastomer has a first groove extending at least partially along the recess.
