In order to ensure homogeneous and reliable spraying of a multi-component blend, a spray gun (1) is disclosed, the housing of which encompasses both a combination of check valves (42) and safety valves (46) and a switching unit (10). One element (12) consisting of a mixing box (8) and a tail pipe (9) is removably fixed to said box and, consequently, can be replaced by another either because the conditions have changed or because it is clogged. The check valves (42 and 46), disposed one after the other, ensure that both or all components are fed under the same pressure to the mixing box (8), and the tail pipe (9) fitted on said box enables the desired jet to be obtained. |
