Definitions

  • the invention relates to an electromagnetic actuating device according to the preamble of claim 1.
  • Such an adjusting device is known from DE-A-30 24 109.
  • the device described there has a single shaft, which is connected to the valve disk of an internal combustion engine and carries at its other end an anchor plate which can be moved back and forth between two magnets.
  • An actuating magnet is provided in order to lead the equilibrium point of the spring system into an operating position at the start of operation, for this purpose an abutment for the base point of the spring system must be displaced. It is important that, insofar as the shaft is also guided by the abutment, no canting occurs during the movement of the abutment, so that the shaft is guided with as little friction as possible after the abutment has reached the working position.
  • the object of the invention is to provide a generic device in which malfunctions caused by tilting of the abutment during the movement from the rest position to the operating position are avoided.
  • the abutment has a sleeve-shaped receptacle for the shaft-shaped approach, with the help of this sleeve-shaped receptacle, the abutment is guided according to the shaft and can reach its exact working position.
  • the stem of the valve is separated from the control element, so the arrangement is divided into two.
  • the configuration according to the invention ensures that the control shaft is properly guided in this division.
  • the abutment has bevels which cooperate with corresponding bevels in the working position, so that self-centering takes place.
  • an anchor plate connected to the control element runs into a guide and during commissioning the anchor plate and the sleeve-shaped receptacle for the shaft-shaped attachment ensure that the abutment is displaced into the intended working position.
  • the sleeve-shaped extension now serves to guide the shaft and thus to guide the anchor plate in order to enable the anchor plate to work in a precisely aligned manner.
  • the core of the method according to the invention is thus characterized in that first the anchor plate with the shaft guides the abutment and its sleeve. After the centering, the abutment and the sleeve now serve to guide the shaft with the anchor plate.
  • Reference number 10 shows the cylinder head of the engine block of an internal combustion engine.
  • the cylinder chamber 16 is vented through an outlet valve, which opens an outlet channel 14 when the valve plate 20 opens.
  • the valve is controlled by an electromagnetic actuator.
  • a stem 24 leads out of the valve head 20 out of the cylinder head 10 and slides in a sleeve 26 in the cylinder head.
  • the end of the valve stem 24 is designated by the reference numeral 28, there it has a support on which a stamp head 40 to be described later strikes.
  • a ring 30 is flanged circumferentially, which serves as an abutment for a spring system, which is composed of a large coil spring 32 and a small coil spring 34.
  • the two coil springs 32 and 34 run coaxially into one another, the opposite base 36 is a support in the cylinder head.
  • the valve stem 24 can be moved in the slide bearing 26 against the force of the spring system 32 and 34, the valve plate 20 then lifts from its seat and opens the outlet channel 14.
  • valve stem 24 The axial extension to the valve stem 24 forms a stem 38 of a control element, which has a punch head 40 at its lower end for contact with the valve stem 26.
  • annular anchor plate 46 which consists of ferromagnetic material, adjoins the shaft 38 of the control element.
  • a spring system consisting of a large coil spring 42 and a small coil spring 44 rests on the anchor plate, which likewise run coaxially with one another and coaxially with the shaft 38 of the control element.
  • This spring system 42 and 44 is formed by a support 48, which will be discussed later.
  • a magnetic core 68 which is U-shaped in cross section, is arranged in a ring, the axis of the ring coincides with the axis of the valve stem 24.
  • a coil 66 which is U-shaped in cross section, the magnetic core 68 in FIG Opened towards anchor plate 46.
  • the shaft of the control element is surrounded by a similarly designed magnetic core 62 which carries a coil 64 in its interior.
  • the anchor plate 46 moves, depending on the excitation of the magnet 62 or 66, from contact with the magnetic core 64 to contact with the magnetic core 68 and back.
  • an actuating magnet which consists of a magnetic core 58 and a coil 60.
  • a ferromagnetic element 56 is attracted is connected to a sleeve 70.
  • the magnetic core 58 has a bevel on its working surface, which defines a type of cone jacket, since the magnetic core 58 surrounds the shaft 38 of the control element in a ring shape.
  • the ferromagnetic element 56 is likewise provided with a bevel 80, so that when it is attracted by the magnetic core 58, its bevel 80 comes exactly on the bevel of the magnetic core 58 and thus centers itself in its attracted position.
  • a sleeve-shaped receptacle 70 is connected to the ferromagnetic element 56, in which the shaft 38 of the control element is guided.
  • the sleeve-shaped receptacle 70 forms a pipe 82 in which the shaft 38 can slide back and forth.
  • the ferromagnetic element 56 Due to the excitation of the coil 60, the ferromagnetic element 56 is attracted and centered with the aid of its bevel 80, so that the sleeve-shaped receptacle 70 moves downward and thus displaces the abutment 48 for the base point of the spring system 42 and 44.
  • the switching magnet 64 is first excited, which moves the control element into its one switching position, preferably into the closed position.
  • the control element 38 is thus in a defined position, and the subsequent excitation of the actuating magnet 60 transfers the point of equilibrium of the spring system 42 and 44 from an eccentric position between the magnets 62 and 66 to the central position between the respective switching magnets, so that now one symmetrical sequence of movements of the control element 38 between the two magnets 62 and 66 can take place.
  • the armature plate 46 is held by the magnet 62 during the excitation of the actuating magnet 60 and is therefore relatively rigid.
  • the shaft 38 of the control element fixed in this way thus moves in the bore 82 and therefore serves to guide the sleeve-shaped extension 70, so that the channel 82 is precisely aligned into the working position after the movement of the ferromagnetic element. At this time, the bevels 80 take over the exact centering.
  • the bore 82 now serves for the exact guidance of the shaft 38 of the control element, the anchor plate 46 also sliding back and forth with its edge in a guide 86. Tilting of the anchor plate is now avoided by the sleeve-shaped receptacle 70, whereas previously the tilting of the sleeve-shaped receptacle 70 was prevented by the fixed anchor plate 46.
