Abstract (en)
[origin: WO2005054725A1] A transfer device, which transfers a displacement of an actuator, particularly for an injection valve, has a housing (5) comprising a first recess inside of which a first and a second plunger (6, 7) are displaceably mounted. The first and second plunger (6, 7) are actively connected via at least one transfer chamber (10, 11) by means of a fluid. The active connection causes the second plunger (7) to be displaced when the first plunger (6) is moved and vice versa. The transfer chamber (10) is hydraulically coupled via a sealing gap (21) to a compensating chamber (22) that compensates for, in a delayed manner, the pressure differences between the transfer chamber (10, 11) and the compensating chamber (22). The transfer device also comprises a chamber device with a chamber that is the compensating chamber (22), with a chamber housing that is the housing (5), and with a plunger that is the first plunger (6). The chamber device comprises a device with a first body, which has a recess, a second body, which is introduced into the recess, and with an elastomer (50), which is placed in the recess between the first and second body whereby, in this area, closing and sealing the space between the first and second body. The elastomer (50) has a first groove (61) extending at least partially along the recess while located at distance from the wall of the recess.
