Abstract (en)

[origin: EP0416349A2] During cleaning, a pulsating air stream can be fed to a spinning rotor (1) by means of a switching device (6). The switching device (6) is assigned a shut-off device (5). The switching device (6) possesses a housing (60) having a pressure chamber (62), into which opens a control-air feedline (4) connected to a compressed-air source (3). Furthermore, a control-air discharge line (40) opening into the housing (60) is provided. Located in the housing (60) is a closing member (7) for the alternate connection and separation of the pressure chamber (62) and control-air discharge line (40). The feed of compressed air from the compressed-air source (3) to the compressed-air line (2) is controlled in this way. The closing member (7) is loaded in one direction of movement by the pressure effective in the pressure chamber (62) and in the opposite direction of movement by a compression spring (65). <IMAGE>
