  • Pressure regulating check valve
    Patent number: 11649695
    Abstract: Apparatuses and methods for pressure regulating check valve assemblies are described. In an example, the check valve assembly comprises a housing defining a fluid passage having a fluid inlet side and a fluid outlet side. A lift check valve positioned within the fluid passage oriented to restrict fluid flow from the fluid inlet side and a second check valve positioned within the fluid passage oriented to restrict fluid flow from the fluid outlet side. A flow dampener is positioned within the fluid passage and between the first and second check valves.
    Type: Grant

  • Pressure testable tubing connection
    Patent number: 8186202
    Abstract: An apparatus for sealing tubing to a device, the apparatus including: a first seal configured to seal the tubing to the device, the first seal having a device side in contact with the device and an interior side opposite the device side; a test sleeve configured to surround the first seal and to seal to the device using a second seal; a third seal disposed at the test sleeve and configured to seal the tubing to the test sleeve wherein the test sleeve, the second seal, and the third seal form a pressure boundary about the first seal; a test port disposed at the test sleeve, the test port being in communication with seals, wherein the test port is configured to connect to a seal test device to test the integrity of the seals in communication with the test port; and a plug configured to seal the test port.
