Abstract
A feed valve for the quick discharge of an accumulator includes a piston with a small clearance relative to a cylinder. The piston has a rear face carrying a guide block which maintains the piston in proper position by cooperation with a slide. An elastic device, such as a spring, biases the piston to a closed position. The valve arrangement is especially useful for silo products such as granular or pulverulent products.
