Zusammenfassung:	In one aspect the disclosure provides a valve lift arm which includes a main body defining an arm structure for a valve, and a trigger engagement structure defined at one end of the main body. Also provided is a valve engagement structure defined at the distal end of the main body to the trigger engagement structure, with the valve engagement structure providing a vertical pivot connection to the valve and facilitating operation of the valve through vertical motion of the end of the main body. A pivot structure is provided which divides the main body into a valve part which incorporates the valve engagement structure and a trigger part which incorporates the trigger engagement structure. The pivot structure includes an axle which allows rotational motion of the trigger part relative to the valve part, the allowed rotational motion having a horizontal or lateral component.
