Patent number: 11719353Abstract: A pressure valve includes a housing having bottom portion defining a bottom opening configured to be in communication with a vessel and a sidewall defining an internal cavity. The housing includes a vent aperture configured to provide fluid communication between the internal cavity and ambient air surrounding the pressure valve and an accessory aperture configured to couple an accessory to the housing. A seal seat is positioned within the internal cavity fluidly between the vent aperture and the bottom opening. A pressure control assembly is coupled to the housing. The pressure control assembly breaks a sealing engagement with the seal seat to provide fluid communication between the vessel and the vent aperture in response to a desired positive pressure being reached within the vessel or in response to a negative pressure being reached in the vessel. The accessory aperture is positioned between the bottom opening and the seal seat.Type: GrantFiled: August 10, 2022Date of Patent: August 8, 2023Assignee: Spike Brewing LLCInventors: Benjamin Caya, Adam J.
