  • Patent number: 5842500
    Abstract: An overfill preventing valve (20) is adapted to be operatively interposed in a flow path between a fluid source (21) and a compressed fluid storage cylinder (22) to prevent the cylinder from being overly filled. The improved valve includes an elongated tubular body having a first seat (25), a first space (26), a second space (28), a second seat (29), a third space (30), a third seat (31), a fourth space 37 and an entrance portion (32) communicating with a source. A passageway (33) continuously communicates the first and fourth spaces. The second and fourth spaces communicate with the interior of the cylinder. A float (36) is contained within the body for movement toward and away from the first seat in response to the liquid level in the cylinder. A valve member (38) is mounted on the body for sealed movement toward and away from the second seat. This valve member separates the first space from the second space. The valve member is biased to move away from the second seat.
