Abstract
The vibrator operated by compressed air imparts vibration to a vibratory conveyor. The vibrator comprises a base, a forward stroke chamber formed by a continuous seal situated on the side of the base facing the conveyor, and a striker mounted on the seal of the forward stroke chamber. The striker interacts with the conveyors under the action of the air for the purpose of imparting vibration. The vibrator also comprises a reverse stroke chamber formed by an additional continuous seal situated on the side of the striker facing the working platform and connected to the surface of the fluid medium.
