Injecting device, particularly for injecting fluid into exhaust system of internal combustion engine, has hollow space that is connected with external gas reservoir for receiving gas volume
摘要
<p>The injecting device (1) has a hollow space (22) that is connected with an external gas reservoir for receiving a gas volume. The hollow space is designed such that the gas volume encloses fluid in the hollow space. The fluid is provided in the injecting device. The hollow space is formed in valve needle (16). An independent claim is also included for a method for increasing cold compressive strength of an injecting device.</p>
