Abstract
A stabilizer cartridge for enhancing stability of a fluid regulator is provided. The stabilizer cartridge includes a body, a first disk, and a second disk. The body has a through-bore and an external flange. The first disk has one or more windows and an aperture, and is fixed on an exterior surface of the body. The second disk is slidable along the exterior surface of the body and is biased into contact with the first disk by a biasing element that is positioned between the external flange and the second disk.
Claims16
A stabilizer cartridge, comprising:
- a body having an internal bore, an internal counterbore, and an external flange;
- a first disk having one or more windows and an aperture, wherein the first disk is positioned around an exterior surface of the body;
- a second disk that is slidably positioned around the exterior surface of the body between the external flange and the first disk, wherein the second disk is configured to restrict fluid communication through the one or more windows but not through the aperture when the second disk contacts the first disk;
- and
- a biasing member that is positioned around the exterior surface of the body between the external flange and the second disk, wherein the biasing member biases the second disk toward the first disk;
- wherein the stabilizer cartridge is insertable, as an assembly, around a valve stem with the valve stem being receivable in the internal bore and at least a portion of a stem guide being receivable in the internal counterbore.
A stabilizer cartridge, comprising:
- a first disk having a plurality of windows and an aperture, wherein the first disk is fixed on a cylindrical body that has a through-bore and a counterbore;
- and
- a second disk that is movably positioned on the cylindrical body and biased into contact with the first disk, wherein the second disk has a smaller radius than the first disk;
- wherein the stabilizer cartridge is slidable, as an assembly, along a valve stem into its operating position, and wherein the counterbore is configured to receive a portion of a stem guide.
A stabilizer cartridge, comprising:
- a body having a through-bore, a counterbore, and an external flange;
- a first disk having one or more windows and an aperture, wherein the first disk is fixed on an exterior surface of the body;
- and
- a second disk that is slidable along the exterior surface of the body, wherein the second disk is biased into contact with the first disk by a spring that is positioned between the external flange and the second disk;
- wherein the stabilizer cartridge is configured to be installed, as an assembly, along a valve stem with the valve stem being received in the through-bore and a stem guide being received in the counterbore.
