Definitions

the invention relates to a preamble of claim 1 Device with an electromagnetic actuator for actuating a gas exchange valve an internal combustion engine, comprising both sides of a stroke oscillating drivable armature provided switching magnets in a multi-part, the machine-side arrangement serving support, which acts as a frame-like Housing with spaced support beams connected in one piece via crossbeams is formed, and the support bracket between the stroke direction of the armature between divided the crossbar and for a machine-side arrangement of an actuator arranged secured relative to each other clamped against one another by clamping means are.
the invention has for its object the generic device for actuation further develop several gas exchange valve, this goal with one simplified structure is achieved by breaking separation.
actuators for essentially aligned gas exchange valves arranged in series Cylinders of the internal combustion engine in a common, strip-like design Housing are arranged, and the housing by means of breaking the support beams is divided in two at about the level of the resting anchor, with the essentially simultaneous fracture separation of the support beams between the anchor stroke direction between Breakage notches have approximately averaged passageways that coincide with cross to the anchor lifting direction essentially parallel clamping screws.
a device 1 with an electromagnetic actuator 2 for actuating a Gas exchange valve 3 of an internal combustion engine comprises on both sides of a stroke oscillating armature 4 provided switching magnets 5 and 6 in a multi-part, the machine-side arrangement supporting device, which as a frame-like housing 7 with cross members 8 and 9 in one piece connected, spaced support beams 10 is formed, the support beams 10 divided transversely to the stroke direction of the armature 4 between the cross members 8 and 9 and secured for a machine-side arrangement of the actuator 2 relative to each other Arranged clamped against one another via clamping means 11 designed as clamping screws are.
this device 1 for the purpose of actuating several, in several Cylinders of the internal combustion engine, not shown, arranged gas exchange valves with the further objective of a structure of the Device 1 is proposed according to the invention that actuators 2 for essentially aligned gas exchange valves 3 arranged in series Cylinders of the internal combustion engine, not shown, in a common, strip-like designed housing 7 are arranged.
the strip-like housing is used to achieve safe breakage separation 7 cast from a silicon, particle or fiber-containing light metal alloy.
coil cores 14 formed from core sheets of the switching magnets 5 and 6 with the support beams 10 and / or with sections of the cross members 8 and 9 each for heat dissipation in a flat system, the coil cores 14 being unprocessed poured into the housing 7 or processed subsequently used and are arranged cohesively or non-positively / positively.
a structurally simple construction of the housing 7 is further achieved in that a housing section 7 'between two adjacent support beams 10 several Coil cores 14 corresponding to several gas exchange valves 3 of a cylinder Inlet and one outlet valve or two similar gas exchange valves for Inlet and outlet - are arranged, with the coil cores 14 at both ends have open, channel-like recesses 15 for receiving sections magnet coils 16 running outside the coil cores 14, as is the case with a outer housing section 7 'can be seen in Figure 3.
This design of the Solenoid coils 16 serve on the one hand for a simple connection of the ones not shown Power and control lines and, on the other hand, is intended for additional cooling the magnetic coils 16.
the strip-like housing 7 protrudes on the cylinder head-side crossbar 8 arranged extensions 22 with relative small contact surfaces in a thermally conductive connection with cooled contact surfaces on the cylinder head 23, the two-part for assembly purposes and by means of separate, not shown screws one-piece handle 7 housing through clamping screws 11 is attached to the cylinder head 23.
the cabling module 24 preferably arranged on one of the cover strips 21 24 via a wall opening in the cylinder head 23, not shown is led to the outside.
