  • Patent number: 11126210
    Abstract: An electrically operated valve assembly having a manual override includes a valve body, an actuation cam, a shaft, a gear, and a biasing member. The shaft is connected to the actuation cam and includes a projection. The gear defines an opening which selectively receives the projection of the shaft to engage the shaft to the gear. In a first operating condition of the valve assembly, the actuation cam is in an engaged position relative to the valve and the shaft is biased to be engaged with the gear. In a second operating condition of the valve assembly, the actuation cam is in a disengaged position offset along the axis of the shaft from the valve handle and at least partially rotated about the axis of the shaft such that the shaft is disengaged from the gear. Further, a master control module can control one or more such valve assemblies.

  • Patent number: 11077748
    Abstract: A shutoff vent is disclosed. A main body has a first end and a second end. The main body defines a first opening towards the first end, a second opening towards the second end, and a mating port between the first opening and the second opening. The first opening and the second opening are in communication through the mating port to define a gas passageway. A translatable plug is disposed within the main body, and the gas passageway extends past the translatable plug. The translatable plug is configured to reversibly translate towards the second end to sealably obstruct the mating port. In some examples, the translatable plug is configured to translate towards the second end when force is applied to the translatable plug from the first end.
