摘要： The invention relates to a functional unit (20) of a supply tank (19) of an injection device (15) for a liquid reducing agent in an exhaust gas post-treatment device (3) comprising a catalyst (11) for selective catalytic reduction (SCR). The functional unit (20) is essentially equipped to convey the reducing agent from the supply tank (19) in a targeted manner and to prevent the reducing agent from freezing at least in the region of the functional unit (20) at extremely low temperatures. The functional unit (20) is designed such that it is not damaged when the reducing agent freezes.

摘要： The invention relates to a device for ventilating an exhaust gas after-treatment system (10), with which a freezable operating/auxiliary agent, in particular a reduction agent, is metered into an exhaust tract (12) of an internal combustion engine. A hydraulic spring accumulator (60, 66, 68) stores energy during operation with system pressure. Upon shut-down of the internal combustion engine, said accumulator releases the energy without current such that a vacuum for suctioning the operating/auxiliary agent out of components of the exhaust gas after-treatment system is generated.

摘要： The invention relates to a device (40) for reducing pollutants, in particular nitrogen oxides, in an exhaust gas flow of an internal combustion engine, comprising a reducing agent (46), in particular a urea-water solution, which is stored in a storage tank (42), a metering module, in particular a nozzle (68), for injecting the reducing agent (46) into the exhaust gas flow, and a pump (56, 100) for delivering the reducing agent (46) from a suction point (62) in the storage tank (42) to the metering module via lines (58, 66). According to the invention, the pump (56, 100) lies beneath a reducing agent level (44) in the storage tank (42), and a non-return valve is provided. As a result of the non-return valve, the device (40) is prevented from refilling with the reducing agent (46) after the reducing agent (46) is completely sucked back from the device (40) after shutting off the internal combustion engine, in particular after extended idle times of the internal combustion engine. In a first embodiment, the non-return valve is a filter (64) that is formed with a plurality of screens (80, 82, 84, 86) which are connected one behind the other, which have a special microstructure, and which are formed with a plastic material. In the case of a second embodiment, the non-return valve is formed with a hermetically sealing valve (158) which is heavily preloaded by a spring force in particular and which is directly integrated into the pump (100) that is necessary for delivering the reducing agent (46) in the device (40).

摘要： The invention relates to a storage tank (10) for receiving a medium (12) that can be frozen, in particular a reducing agent, comprising a ventilation unit (34, 36; 72) and a crucible-shaped container (22) introduced in the storage tank (10). An air chamber (50) in the crucible-shaped container (22) is connected via a ventilation line (60) or an overflow opening (40) to an air chamber (48) of the storage tank (10), which is ventilated via a ventilation unit (34, 36; 72).
