Abstract

An exhaust gas recirculation valve which comprises a stub pipe which protrudes into a pipe and with whose opening a valve element interacts, which valve element is moved by an actuator, the actuator being connected to the stub pipe by means of a connecting part in such a way that the above mentioned parts can be jointly inserted through a first opening into the pipe, a closing part of the stub pipe closing a second opening of the pipe, at which location an outwardly protruding end of the stub pipe is connected to an exhaust gas recirculation conduit. The connecting part advantageously also serves to relay measurements of a measurement recording device, recorded at the stub pipe to the analysis device of the measuring device.
