Patent

CA 2385080

The invention relates to a device for controlling capacitive actuators for fuel injection valves for instance. The actuators comprise an energy source (V) and a charging capacitor (C1). A series connection of the primary coil (w1) pertaining to a transformer and a charging switch (S1) is arranged in parallel to the charging capacitor and in the device. A series connection respectively is arranged in parallel in relation to the series connection consisting of the secondary coil (w2) of the transformer and a decharging switch (S2), whereby said first series connection consists of an actuator (P1 to Pn) and a selector switch (A1 to An) allocated thereto. Diodes (D1, D2) are switched in parallel to the charging switch (S1) and the decharging switch (S2).

L'invention concerne un dispositif pour commander des organes de réglage capacitifs, par exemple pour soupapes d'injection de carburant, qui comprend une source d'énergie (V) et un condensateur de charge (C1). Dans ce dispositif, un montage en série constitué de la bobine primaire (w1) d'un transformateur et d'un commutateur de charge (S1) est monté en parallèle au condensateur de charge. En parallèle au montage en série constitué de la bobine secondaire (w2) du transformateur et d'un commutateur de décharge (S2) sont montés, respectivement, un montage en série constitué d'un organe de réglage (P1 à Pn) et d'un commutateur de sélection (A1 à An) associé à cet organe de réglage. En parallèle au commutateur de charge (S1) et au commutateur de décharge (S2) sont montées des diodes (D1, D2).
