Abstract
A compensating element (30) for an injection valve has a cup-shaped body (32) with a cup base (34) and a recess. Furthermore, the compensating element has a piston (36) which makes a clearance fit in respect of the recess of the cup-shaped body (32) on an axially extending guide segment (41) of the piston (36) and which is arranged at least partially axially moveable with the guide segment (41) in the recess of the cup-shaped body (32). A sealing element (44) is arranged on the side of the guide segment (41) facing away from the cup base (32) and couples the cup-shaped body (32) with the piston (36). A hydraulically and/or pneumatically sealed system is delimited by the cup-shaped body (32), the piston (36) and the sealing element (44). The coupling of the sealing element (44) with the cup-shaped body (32) and/or the piston (36) is friction-fit.
