Abstract

Bei einem elektromagnetischen Aktuator (1,1') zur Betätigung eines Gaswechselventils einer Brennkraftmaschine sind in einer vereinzelte, beabstandet angeordnete Stützträger (11,11',22,22') umfassenden Trageinrichtung (5) geblechte Spulenkerne (6,7) zwischen den Stützträgern jeweils mit deren Innenseiten (12,12') flächig auf wärmeleitenden Anschlag angeordnet, wobei in den Spulenkernen lediglich abschnittsweise verlaufend angeordnete Magnetspulen (9,10) über außenseitig um die Stützträger verlaufend angeordnete Abschnitte (9',10) geschlossen sind.

Figure 00000001
In an electromagnetic actuator (1, 1 ') for actuating a gas exchange valve of an internal combustion engine, laminated coil cores (6, 7) are located between the support brackets in an individual support device (5) comprising spaced-apart support supports (11, 11', 22, 22 ') in each case with their inner sides (12, 12 ') arranged flat on a heat-conducting stop, magnetic coils (9, 10) running in sections in the coil cores only being closed via sections (9', 10) running on the outside around the support beams.
