<p>An apparatus imparts movement to fluid dispersing nozzle (36) with a mechanism for converting rotational movement about an axis of rotation into orbital movement about the axis of rotation, and an elongate member (30) is connectable to the mechanism at one end and is connectable to a fluid nozzle at an opposite end from the mechanism. The orbital member provides orbiting movement of the opposite end in response to rotation of the mechanism about the rotational axis, and provides stationary centered positioning of the opposite end in response to a non-rotating mechanism. A speed multiplier transmission or gearbox can be provided between the motor shaft and drive spindle if desired. A separate mixer is positionable within the member and is moveable longitudinally with respect to the member during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone.</p> |
