ABSTRACT:
Disclosed is a travel-transmitting element for an injection valve, comprising a pressure-loaded storage chamber which is filled with a hydraulic fluid and a storage element that is provided with an elastomeric bellows-type member. In order to ensure sufficient steadiness of the rotational speed over the service life, the inventive elastomeric bellows-type member is provided with a stiffening element which ensures constant radial stiffness over the service life at least in some sections thereof.
