Auxiliary framework for electrically latched rocker arms

A valvetrain for an internal combustion engine of a type that has a combustion chamber, a moveable valve having a seat formed in the combustion chamber, and a camshaft, comprising:

• a rocker arm assembly comprising a rocker arm;
• an electromagnetic latch assembly including an electromagnet and a latch pin;
• and
• a framework that supports a conductor that is part of a circuit that includes the electromagnet;
• wherein the framework holds a component of the electromagnetic latch assembly adjacent the rocker arm assembly;
• the electromagnet is mounted to the framework;
• and
• the electromagnet is operable to cause the latch pin to translate between a first position and a second position through a magnetic flux that passes between the rocker arm assembly and the component of the electromagnetic latch assembly held adjacent the rocker arm assembly by the framework;
• wherein the electromagnet is operable to cause the latch pin to translate between the first position and the second position through the magnetic flux that passes through the rocker arm;
• one of the first position and the second position provides a configuration in which the rocker arm assembly is operative to actuate the moveable valve in response to rotation of the camshaft to produce a first valve lift profile;
• and
• the other of the first position and the second position provides a configuration in which the rocker arm assembly is operative to actuate the moveable valve in response to rotation of the camshaft to produce a second valve lift profile, which is distinct from the first valve lift profile, or the moveable valve is deactivated.
