  • the cylinder chamber 21.1 is controlled via an electrically actuated control valve 33 and the cylinder chamber 22.1 via an electrically controllable control valve 34 can be acted upon with compressed air, so that upon activation of the control valve 34 and acting on the cylinder chamber 22.1 with compressed air, the piston rod 17 against the action of the compression spring 26 from her Starting position is moved over a first shorter movement stroke A in a first stroke position, which is defined by the fact that the piston 27 comes to rest against the stroke stop 29.
  • the piston rod 17 Upon activation of the control valve 33 or pressurization of the cylinder chamber 21.1 with the piston 27, the piston rod 17 is moved against the action of the compression spring 26 in a second, larger movement stroke B from the initial position to a second stroke position, which is defined by that formed by the section 17.1 upper end of the piston rod 17 comes against the stroke stop 30 to the plant.

  • the first stroke position corresponds to a partially opened filling valve 12 and the second stroke position (to movement stroke B) corresponds to the completely opened filling valve 12.
  • the control of the filling valves 12 and their actuators 18 takes place in the filling machine shown in Figure 1 by a central machine control and / or provided by the rotor 1 decentralized control units 35, for example for each filling station 3 separately or for a group of filling stations 3 are provided together, for example, generally in such a way that whenever the filling station 3 has reached a predetermined position of the rotational movement of the rotor 1 and the bottle to be filled 2 is in sealing position on the filling element 4, the filling valve 12 in question is opened, for example stepwise in the form that initially for a slow filling by activation of the control valve 34, the piston rod 17 of the respective filling valve 12 with the piston 27 in the first stroke position and Thus, the valve body 16 are moved to the first open position, and then then for a quick filling by activating the control valve 33, the piston rod 17 and thus the valve body 16 are moved to the second stroke position and in the second open position.
  • the (weight gain) measured by a weighing device 37 will, for example via the control unit 35, the closing of the filling valve 12 initiated.
  • This closing is again stepwise, for example, in such a way that when the control valve 34 is activated, the control valve 33 is deactivated, so that when the cylinder chamber 21.1, but still pressurized cylinder chamber 22.1, the piston rod 17 returns from the second stroke position in the first stroke position and thereby the Fill valve 12 is partially closed.
  • the filling process is then terminated by the fact that the control valve 34 is deactivated, so that the piston rod 17 are moved by the action of the compression spring 26 in its initial position and thus the valve body 16 in the closed position with non-pressurized cylinder chamber 22.1.

  • the setting of the lifting stops 29 and 30 can be carried out for each filling station 3 or for each actuating element 18 individually and individually, but also in groups for several actuating elements 18 at the same time, namely quickly and conveniently via the external machine control and / or via the decentralized control units 35 ,
  • the machine control or the decentralized control units 35 form so that on command or request and as a function of measured during the filling process filling parameters, such as flow rate, temperature of the filling material, ambient temperature, filling pressure, etc., the (filling parameters) corresponding sensors are detected, for example, from the inductive flow meter 36, from the weighing device 37, not shown thermometers and manometers, etc., an automatic tracking or readjustment of the lifting stops 29 and 30 takes place, for example, with a in the central machine control and / or program stored in the decentralized control units 35 for achieving a homogeneous filling process or filling pattern and for optimum performance of the filling machine.

  • actuating elements 18 are used to control filling valves in filling machines, it is of course not necessary for these filling valves to have the design described in connection with FIGS. 1 and 2. Other constructive versions of the filling valves are possible.
  • the actuators 18 can be used specifically for controlling filling valves in filling elements so that with a stroke stop the closing state of the respective filling valve or the closing state corresponding position of the piston rod of the actuating element is defined at least during the running filling machine.
  • the position of the piston rod 17 corresponding to the closing state of the filling valve 12 would then be determined by the stroke stop 29, while the stroke stop 30 corresponds to the stroke position of the filling valve corresponding to the open state of the filling valve Piston rod 17 determines.
  • This version has the advantage that when closing the respective Filling valve 12, the closing movement of the valve body 16 is braked by the pneumatic pressure in the cylinder chamber 22.1 and the valve body 16 thus gently against the valve seat comes to rest, so that thereby wear of the filling valves 12 is avoided or substantially reduced.
