Abstract
Briefly, the invention comprises a vibrator with an on-demand start-up system, that inhibits fouling the atmosphere, with one embodiment of the invention including an integral non-fouling start-up system wherein at least one of the bearing surfaces contains a surface adhered lubricant so as to provide an on-demand static start-up system and in another embodiment the on-demand start-up system is a dynamic system that can unbalance the differential forces on the piston therein to ensure that the vibrator will begin vibrating 'on-demand'. Thus, two types of start-up systems are available one an on-demand static start-up system and the other an on-demand dynamic start-up system with either of the systems can be used alone or if desired in combination to provide redundant start-up systems.
