ABSTRACT:
An emptying balance contains a product flow setting device, which contains a rotary slide valve. The angle between a rotary slide valve wall and the facing fixed wall is consequently dependent on the opening position of the rotary slide valve. A fine blocking flap is also provided which is opened by means of two pressure cylinders arranged in series, and which are individually controllable. For subsequent metering of small product quantities only one of the two pressure cylinders is operated and this only leads to a limited opening of the fine blocking flap.
