Abstract
A solenoid valve actuating apparatus wherein an actuating circuit for controlling exciting currents to electromagnets for actuating a plurality of engine valves so that the engine valves will be opened and closed can be formed by a small number of switching means is provided. Two of the engine valves form one engine valve group, and the actuating circuit is provided for each of the engine valve groups. The actuating circuit includes three series circuits each having three switching means connected in series between a first line terminal on a high voltage side and a second line terminal on a low voltage side. Four of the electromagnets each corresponding to each of the engine valve groups connect connecting-in-series portions between the switching means between different series circuits.
