Abstract
A pressure gas connection of a reverse-flow device with the pressure gas feed conduit (2) in dust-laden gas filters is disclosed. The reverse-flow device is formed as a two-stage injector. In dust-laden gas filters which are provided with such a reverse-flow device, each individual injector (1) is connected in a manner which is as gas-tight as possible to the pressure gas feed conduit (2). In order to create a rapidly and easily mountable pressure gas connection for injectors (1) which does not require any additional seals, the connecting sockets (1a) of the injectors (1) of the first stage are inserted over the pressure-gas feed conduit (2) alternating with spacer sleeves (3). A stationary sleeve (4) is inserted over one end of the pressure gas feed conduit (2) and a movable end sleeve (5) is inserted over the other end of the pressure gas feed conduit (2). The movable end sleeve protrudes beyond the pressure gas feed conduit (2) in axial direction and is provided with a clamping device (6) which presses the connecting sockets (1a) and the spacer sleeves (3) in axial direction against the stationary sleeve (4).
