Abstract
A device (10) to control the position of a valve (12) in relation to the position of a unidirectionally rotating member (22) includes the use of a valve drive wheel assembly (24) which is movable in a reciprocating rotational manner, a flexible arm assembly (23), and a flexible rod assembly (25). The flexible arm assembly (23) is in operative association with the unidirectionally rotating member (22) and the valve drive wheel assembly (24) for driving the valve drive wheel assembly (24) in rotational reciprocation as the unidirectionally rotating member (22) rotates. Flexible rod assembly (25) linearly reciprocates the valve (12).
