Abstract
Abstract A valve device serving to prevent overfilling of portable containers, particularly liquid gas cylinders, includes a ball which is freely rotatable relative to a spherical seating face in a casing having a filling channel extending to said seating face. The ball has a through passage which in the prescribed filling position communicates with the channel, and the ball is connected to a load member tending to keep the ball, and thus its passage, in a given orientation so that the communication is broken when the container is tilted away from the prescribed filling position. The device further includes a valve member controlled by a float and operative to interrupt the filling operation after a predetermined filling level has been reached in the container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
A valve device to prevent overfilling of portable containers, particularly liquid gas cylinders,comprising a casing having a spherical surface and a fluid filling channel opening in said spherical surface, a valve member for automatically obstructing the filling flow when a predetermined level has been reached in the container, a freely rotatable ball resting against said spherical surface, a passage extending through said ball, and a load member associated with the ball and extending downwardly therefrom to normally hold the ball in such a position relative to said casing that during the filling operation said passage communicates with said fluid filling channel only when said container is held in a prescribed filling position, said valve member being housed in said passage and being operatively connected to a float associated with said load member.
Claim 2
Dependent Claim
132 words
A valve device to prevent overfilling of portable containers, particularly liquid gas cylinders,comprising a casing having a spherical surface and a fluid filling channel opening in said spherical surface, a valve member for automatically obstructing the filling flow when a predetermined level has been reached in the container, a freely rotatable ball resting against said spherical surface, a passage extending through said ball, and a load member associated with the ball and extending downwardly therefrom to normally hold the ball in such a position relative to said casing that during the filling operation said passage communicates with said fluid filling channel only when said container is held in a prescribed filling position, said valve member being housed in said passage and being operatively connected to a float associated with said load member.
Claim 3
Dependent Claim
43 words
A valve device according to claim 1, wherein said valve member is connected to one end of a lever which at its other end carries said float and intermediate its ends is supported by a rod connecting the ball with its load member.
Claim 4
Dependent Claim
33 words
A valve device according to claim 1, wherein said load member itself forms a float and is carried by a rod mounted for displacement in said ball passage and carrying said valve member.
