ACTUATOR ARRANGEMENT
First Claim
1. An actuator arrangement for controlling a latching arrangement of a dual body rocker arm of an internal combustion engine, the dual body rocker arm comprising a first body, a second body, and the latching arrangement, the latching arrangement being controllable to latch and unlatch the first body and the second body, the actuator arrangement comprising:
- an actuation source;
a shaft comprising a cam configured to control the latching arrangement; and
a gear mechanism configured to translate a continuous rotation of the actuation source into an intermittent rotation of the shaft in steps of a predefined degree,wherein, in use, a continuous rotation of the actuation source is configured to cause, via the gear mechanism, the shaft to rotate in steps of a predefined degree, thereby to change an orientation of the cam relative to the latching arrangement by a predefined amount, so as to control the latching arrangement.

Abstract
An actuator arrangement for controlling a latching arrangement of a dual body rocker arm of an internal combustion engine, the dual body rocker arm comprising a first body, a second body, and the latching arrangement, the latching arrangement being controllable to latch and unlatch the first body and the second body. The actuator arrangement includes: an actuation source; a shaft including a cam for controlling the latching arrangement; and a gear mechanism for translating a continuous rotation of the actuation source into an intermittent rotation of the shaft in steps of a predefined degree. In use, a continuous rotation of the actuation source causes, via the gear mechanism, the shaft to rotate in steps of a predefined degree, thereby to change an orientation of the cam relative to the latching arrangement by a predefined amount, so as to control the latching arrangement.
