Abstract: Valve arrangement for ensuring different amount of medium flow-through comprising at least two chambers (6,7) separated by a limiting wall (3) provided with a through-opening (1). An insertion piece (2) in the through-opening (1) is able to move transversally and the cross-section of its elongated middle portion (4) corresponds to that of the through-opening (1). At least at one end of the insertion piece (2) a closing head (5) is provided. A form-fitting (8) between the closing head (5) and the limiting wall (3) ensures a first closed state thereby a first amount of flow-through from a chamber (6) being on one side of the through-opening (1) to the chamber (7) being on the other side of it when the longitudinal movement of the insertion piece (2) is limited as the closing head (5) abuts against the limiting wall (3) at the through-opening (1).

Abstract: Transmission element device for two-way timing connected mechanically to the surface to be activated (15) of a timed apparatus operated by a controller (37), the surface to be activated (15) is linearly movable against counter-force. The transmission element (1) has a transmission element brake cylinder (7) filled with operating medium. The inner space of the transmission element brake cylinder (7) is divided into a first chamber (19) and a second chamber (21) by a linearly moving transmission element piston (9) having a sealing element (23). The transmission element piston (9) is provided with openings (25, 27) for ensuring the flow of the operating medium between the two chambers (19, 21) in an extent determined separately for each direction. The exit portion (5) of the transmission element (1) is in push contact with the surface to be activated (15), while the transmission element piston (9) is fastened to the controller (37).

Abstract: Auxiliary valve controlled self-cleaning main valve with mechanical operating means. The valve body (1) of the main valve has an inlet (2) and an outlet (3) interconnected through a flow-through opening, and a movable piston (6) having a main closing element (8) at one of its sides and a brake O-ring (9) at its other side. In the control chamber (5) an auxiliary valve (4) with a control valve stem (7) is provided. Between the piston (6) and the auxiliary valve (4) a compressible spring (12) is positioned. The mechanical operating means is provided with a wedge travel path and adapted to press the control valve stem (7) when force is applied externally and to keep it pressed in without applying external force, further it is adapted to release it when force is applied externally and to keep it released without applying external force.
