Abstract: Multidirectional vent limiting devices for use with fluid regulators are described. In some examples, a vent limiting device includes a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The interior surface includes a first sealing surface that defines a portion of the first fluid passageway. In some examples, the vent limiting device further includes a stem and a poppet. In some examples, the stem is rigidly coupled to the interior surface of the housing. In some examples, the poppet includes a second sealing surface that defines a portion of the first fluid passageway, and a radial bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. In some examples, the poppet is slidable along the stem between an open position and a closed position. In some examples, the second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.

Abstract: A vent limiting device adapted to be operably coupled to an exhaust vent of a fluid regulator. The vent limiting device includes a housing, a poppet disposed in the housing, and a retaining element arranged to retain the poppet in the housing. The housing has a fluid passageway extending between a fluid inlet and a fluid outlet. The poppet is movably disposed in the housing, responsive to pressure at the fluid outlet, to control fluid flow through the fluid passageway. The housing includes one or more retaining features that engage the retaining element to retain the retaining element in the housing.

The first end of the stem is rigidly coupled to the poppet. The poppet is slidable in an axial direction within the housing between an open position and a closed position. The second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.
