Definitions
- the invention relates to an actuating device, in particular with actuation by an electromagnet, according to the preamble of claim 1.
- an actuating device for an electrically actuated valve in which the cross section of a throttle bore can be narrowed with the help of a throttle pin, depending on the magnetic excitation of the solenoid coil.
- this valve has the advantage that it can be controlled analogously, i.e. that is, it works continuously and is very simple in construction compared to conventional proportional valves.
- the invention is based on the object of designing an actuating device in such a way that expensive and complex adjustment work with selective assembly can be dispensed with.
- the basic air gap should have a precisely predeterminable size.
- This object is achieved by the actuating device characterized in claim 1.
- the essence of the invention is that the adjustable part is connected to the return spring by a press fit.
- the basic air gap can be adjusted more or less deeply by pressing in a suitable one. Connection vary. If a pin provided with a collar is used as the connecting element between the return spring and the adjustable part, this connection can be implemented in a structurally simple manner with the aid of a spring as tolerance compensation.
- the thickness of the collar arranged on the pin corresponds to the width of the basic air gap, then a simple adjustment of the actuating device is possible by using a flat assembly stamp which presses the pin into the adjustable part until the upper edge of the Federal and the outer upper edge of the return spring lie in one plane.
- FIG. 1 shows a cross section through the actuating device according to the invention for an electrically actuatable valve
- FIG. 2 shows two method steps for setting the actuating and actuating device on a section of FIG. 1.
- a magnet coil 2 is accommodated, which encloses a magnetic core 3.
- An intermediate cover 4 holds the solenoid 2 in the housing 1.
- the intermediate cover 4 holds a sealing ring 5 for sealing the solenoid 2 from other spaces of the valve.
- the housing 1 is closed by a cover 6.
- An expediently operable by the magnetic field of the magnetic coil 2 conical yoke plate 7 is on one side of the ' solenoid 2 and is connected to a pin 8.
- the pin 8 is made of non-magnetizable material and has an extension in the form of an actuating pin 9.
- the actuating pin 9 extends through an opening 10 in the magnetic core 3 to the other side of the magnet coil 2.
- the pin 8 At its one end adjacent to the yoke plate 7, the pin 8 has a collar 11. At the opposite end, the actuating pin 9 carries a valve cone 12 which, together with a valve seat 13, forms a throttle point 14. The throttle point 14 is arranged between an inlet connection 15 and a return connection 16.
- the yoke plate 7 represents the adjustable part of the actuating device, while the magnetic core 3 forms the fixed part.
- a return spring 17 in the form of a disc spring is fixed on its outer circumference in the axial direction in the housing 1. At its radially inner clamping point, the return spring 17 is held in contact with the collar 11 by a spring 18 in the form of a plate spring arranged between the return plate 7 and the return spring 17.
- the thickness of the collar 11 of the pin 8 corresponds to the width of the basic air gap 19 when the magnetic coil 2 is not excited, the upper edge of the collar 11 and the upper outer edge 21 of the return spring 17 lie in the end position of the assembly stamp 20 shown in FIG. 3 in one level. In this state, the return spring 17 is bent exactly by the thickness of the collar 11. If the assembly stamp 20 is then lifted off again, the return spring 17 springs back into its flat starting position, precisely by the thickness of the collar 11. The return spring 17 takes the pin 8 and the back plate 7 with it, so that the back plate 7 is moved up by the thickness of the federal government 10.
- the width of the basic air gap 19 in the axial direction of the valve is then the same size as the thickness of the collar 11. The tolerance of the basic air gap 19 therefore only depends on the accuracy of the thickness of the collar 11. The tolerances of the other parts are eliminated.

Abstract
Un dispositif d'actionnement comprend une partie mobile (plaque de retour 7) retenue à un boîtier (1) par un ressort de rappel (17). Au repos, une discontinuité magnétique (19) déterminée avec précision est formée entre le partie mobile et une partie fixe (noyau d'aimant 3). La partie mobile est reliée au ressort de rappel (17) par un ajustage serré. On peut ainsi modifier la discontinuité magnétique (19) en introduisant plus au moins profondément une connexion appropriée, par exemple une cheville (8), dans la partie mobile (plaque de retour 7).An actuation device comprises a movable part (return plate 7) retained to a housing (1) by a return spring (17). At rest, a precisely determined magnetic discontinuity (19) is formed between the moving part and a fixed part (magnet core 3). The movable part is connected to the return spring (17) by a tight fit. It is thus possible to modify the magnetic discontinuity (19) by introducing more or less deeply an appropriate connection, for example a pin (8), into the movable part (return plate 7).
