The apparatus (10) for generating a mixture of reducing agent and air has a feed pump (16), by which reducing agent is pumped and which has a pump housing (22, 32). The apparatus (10) furthermore has a mixing chamber (50), into which reducing agent and air pumped by the feed pump (16) can be introduced; the mixing chamber (50) is embodied in a mixing chamber body (36). The mixing chamber body (36) communicates directly with the pump housing (22, 32) of the feed pump (16) and forms a cap of the pump housing (22, 32). The feed pump (16) has a drive shaft (24) for a feed element (30), which protrudes into the pump housing (22) of the feed pump (16), and the mixing chamber body (36) is disposed at least approximately radially to the drive shaft (24). The apparatus (10) has a compact structural size and only a slight reducing agent-filled idle volume.
