<p>The valve has a housing (2) in which a disc shaped valve rotates on a diametrical spinole to close a bore (4). The valve cooperates in a closed position, with a valve seat (5). The valve is fixed to two valve spindles (6) which are supported in a vertical, rotatable, external bush (7). The valve spindles have a bore in which an operating spindle (9) is vertically guided. The bore has two sloping grooves, cooperating with two cams so that vertical movement of the operating spindle creates axisl movement of the valve spinole.</p> |
