The work chamber is limited by a housing (1) with a spherically curved surface part (2), to which the peripheries of plates extend. The axes (5,6) of the plates form an angle so that the plate surfaces locate against each other along a fixed sealing line (10). - A tongue (12) locates with a straight edge (14) against the surface of the other plate and with a circular arc-shaped edge (15) against the spherical surface part (2). A suction aperture and a blow-out aperture are arranged on opposite sides of the sealing line (10). |
