ABSTRACT:
A distributor device for compressed air and/or other fluid. The distributor device possesses a distributor housing with a distributor space opening at a longitudinal slot. Adjacent to the longitudinal slot two mutually opposite sealing bars are provided. On the rear side of each such sealing bar there is a secondary pressure space provided in addition to the distributor space and which is arranged to be acted upon by pressure fluid in order to thrust the sealing bar against each other in a sealing fashion. It is in this manner that a reliable sealing action is provided independently of any residual plastic deformation of the material of the sealing bars.
