Device having an injector for a liquid reducing agent, configuration having the device and methods of using the device and the configuration
View Patent ↗A device includes an injector for a liquid having at least one pressure sensor, preferably an integrated pressure sensor. The device is used, in particular, for adding liquid reducing agent to an exhaust gas line of a motor vehicle. A configuration having the device and methods of using the device and the configuration are also provided.
1. A device, comprising:
an injector for a liquid; and
at least one pressure sensor integrated in said injector.
2. The device according to claim 1 , wherein said injector has a housing and said at least one integrated pressure sensor is disposed in said housing.
3. The device according to claim 1 , which further comprises an injection line for feeding the liquid to said injector, said injector having an inlet connected to said injection line.
4. The device according to claim 1 , wherein said injector includes a needle valve having a pressure chamber, and said at least one pressure sensor is in fluid connection with said pressure chamber.
5. A device, comprising:
an injector for a liquid; and
at least one pressure sensor releasably connected to said injector.
6. A configuration, comprising:
at least one tank having a tank bottom;
a chamber disposed at said tank bottom;
an injector configured to be positioned on an exhaust gas line for injecting a liquid into the exhaust gas line;
at least one pressure sensor integrated in said injector; and
a supply unit disposed in said chamber and connected to said injector for supplying the liquid to the exhaust gas line.
7. A method for delivering a liquid reducing agent, the method comprising the following steps:
adding the liquid reducing agent to an exhaust gas line of a motor vehicle with the device according to claim 1 .
8. A method for delivering a liquid reducing agent, the method comprising the following steps:
adding the liquid reducing agent to an exhaust gas line of a motor vehicle with the configuration according to claim 6 .
9. A configuration, comprising:
at least one tank having a tank bottom;
a chamber disposed at said tank bottom;
an injector configured to be positioned on an exhaust gas line for injecting a liquid into the exhaust gas line;
at least one pressure sensor releasably connected to said injector; and
a supply unit disposed in said chamber and connected to said injector for supplying the liquid to the exhaust gas line.
