摘要： Applicator tool positionable within a valve seat bore (2) of a cylinder head (3) for an internal combustion engine, the applicator tool (1) comprising
- a sealing portion (4) extending radially outwardly from a base body (5) of the applicator tool (1) for sealing abutment with the valve seat bore (2),
- a wiper portion (6) extending radially outwardly from the base body (5) and narrower in diameter than the sealing portion (4), and
- a circumferential groove (7) between the sealing portion (4) and the wiper portion (6) and recessed relative to the wiper portion (6), preferably wherein the circumferential groove (7) has a groove base (8) which is circumferentially continuous.

摘要： Valve train (1) for an internal combustion engine, comprising:
- at least one rocker arm (2), wherein the at least one rocker arm (2) is mounted at a bearing (3) and wherein the at least one rocker arm (2) can be moved around the bearing (3) by an actuating element (4)
- at least one valve actuating element (5), wherein the at least one valve actuating element (5) can be moved by the at least one rocker arm (2) and wherein at least one valve (6) can be actuated by this movement of the at least one valve actuating element (5),
wherein a fluid element is arranged between the at least one valve actuating element (5) and the at least one rocker arm (2), wherein
- the fluid element comprises at least one cavity (8) for a fluid
- the volume of the fluid in the at least one cavity (8) can be varied by moving a piston and
- the at least one valve actuating element (5) constitutes or is mounted on the piston.
