Abstract
An electromagnetically-driven valve includes intake valves that are provided in a gasoline engine and that are arranged side by side; a valve plate that connects the intake valves to each other, wherein driving force that is generated by electromagnetic force is transferred to the valve plate; and a changing mechanism that is fitted to the valve plate. The changing mechanism changes the valve drive state between the two-valve drive state, in which both of the intake valves are driven, and the one-valve drive state, in which one of the intake valves is driven and the other intake valve is stopped.
Claims6
An electromagnetically-driven valve, comprising:
- a first valve and a second valve that are provided in an internal combustion engine, and that are arranged side by side;
- a connection member that connects the first valve with the second valve, wherein driving force that is generated by electromagnetic force is transferred to the connection member;
- and
- a changing mechanism that is fitted to the connection member, and that changes a valve drive state between a first state, in which the first valve and the second valve are both driven, and a second state, in which the first valve is driven and the second valve is stopped,
- wherein, in the second state, relative movement between the connection member and the second valve is allowed so that the driving force that is transferred to the connection member is prevented from being transferred to the second valve.
