Abstract

A filling nozzle is provided which has a high flow straightening effect and is capable of forming a stable liquid flow of a circular cross section. In a filling nozzle in which a flow straightening member for straightening the flow of liquid is arranged in a hollow nozzle body, a flow straightening plate with a multitude of fine holes formed therethrough so as to pass the liquid therethrough is used a the flow straightening member, and a divergent chamfered portion, which act as a guide means for guiding fine streams of liquid flowing out from adjacent individual fine holes in a direction to bring them into contact with one another, is formed on an opening edge of an outlet of each fine hole on an outlet side surface of the flow straightening plate.

Claims

1. A filling nozzle in which a flow straightening member for straightening a flow of liquid injected through the interior of a nozzle body is arranged in the hollow nozzle body, characterized in that

said flow straightening member is composed of a flow straightening plate with a plurality of fine holes formed therethrough so as to pass the liquid, and a guide means is formed on a surface of said flow straightening plate at an outlet side thereof for guiding fine streams of liquid flowing out from adjacent ones of the individual fine holes in a direction to bring them into contact with one another.

2. The filling nozzle as set forth in claim 1, characterized in that the shape of the surface of said flow straightening plate at the outlet side thereof is such that a central portion thereof protrudes toward a downstream side more than a peripheral portion thereof does.

3. The filling nozzle as set forth in claim 1, characterized in that the guide means comprises a divergent chamfered portion formed at an outlet of each fine hole.

4. The filling nozzle as set forth in claim 1, characterized in that the guide means comprises circumferential grooves connecting outlets of the individual fine holes to one another.

5. The filling nozzle as set forth in claim 1, characterized in that the guide means comprises radial grooves connecting outlets of the individual fine holes to one another.
