  • Publication number: 20240426392
    Abstract: A thermal sensor assembly for a thermostatic expansion valve includes an enclosure that forms an enclosed interior space containing a thermal sensing fluid, and an opening in the enclosure for charging the thermal sensing fluid. A ball is arranged in the opening and forms a fluid seal between a sealing surface and a sealing interface of the assembly. The sealing surface may be made with a material that is softer than a material of the sealing interface, such that the sealing surface conforms to the sealing interface and fluidly seals the thermal sensing fluid in the enclosed interior space of the enclosure. The opening may include a tapered lead-in hole that tapers radially inwardly as the lead-in hole extends toward the interior space to thereby form the seal. A cover may be attached to an exterior surface of the enclosure to hold the ball in the opening to form the seal.

  • Patent number: 12169023
    Abstract: A shaft seal assembly for sealing a moving shaft of a fluid consumer includes a seal case movable relative to a mating surface of the shaft, a biasing force that biases the seal case towards the mating surface, and a seal at least partially disposed in the seal case. In a dynamic condition, when fluid pressure against the seal case is equal to or greater than a threshold pressure, the seal case sealingly separates from the mating surface, and the seal is forced into sealing engagement against the mating surface of the shaft to form a dynamic seal. In a static condition, when fluid pressure exerted against the seal case is less than the threshold pressure, the seal is sealingly engaged against the mating surface to form a static seal, and the seal case is sealingly engaged against the mating surface of the shaft to form an additional static seal.

  • Publication number: 20240408565
    Abstract: A sparging evaporator for an inerting system including an outer vessel, an inner vessel within the outer vessel, and a plenum formed between the inner and outer vessels. The outer vessel includes a gas inlet for receiving inlet gas into the plenum, and a liquid inlet for receiving liquid fuel into the plenum. The inlet gas in the plenum generates a gas pressure that is exerted against a free surface of the liquid fuel in the plenum thereby forcing the liquid fuel and the inlet gas through an inlet of the inner vessel. The inner vessel contains a lattice structure that promotes liberation of fuel vapor from the liquid fuel and enables the inlet gas in the liquid fuel to sparge the fuel vapor in the liquid fuel, thereby forming a fuel-enriched gas mixture that can be fed to a reactor of the inerting system.

  • Patent number: 12134056
    Abstract: Improvements to filtration and vessels such as for filtration and coalescing of gas streams are shown. A filter element with a partial treated region and untreated region such as providing different surface energies or other filtration characteristics are provided. Various keying arrangements for compatibility and/or rotational locking are shown between the filtration vessel, a tubular coalescing baffle, and/or filter element. The tubular coalescing baffle also may include non-louvered pore structure, which provides for more even flow in a two stage type filtration vessel to prevent premature exiting and reduction of flow velocities along the second stage, and/or may additionally or alternatively include drainage apertures such as drain slot formed along a gravitational bottom or otherwise to facilitate additional drainage of coalesced liquid as opposed to letting such liquid be forced through fluid velocity toward the open end of the tubular baffle.

  • Publication number: 20240353014
    Abstract: A pressure protection valve provides more versatility and improved performance over conventional configurations. The pressure protection valve includes a valve body made of a first material (e.g., plastic) and having multiple integrated fluid connections. A valve base made of a second material (e.g., metal) is connected to the valve body at an inlet portion. A valve stem moves within the valve body to open and close the valve. Fluid connections, therefore, are integrated into the valve body with any suitable number and configuration, which therefore is adaptable with any desired valve base configuration. The valve stem is insertable through the inlet portion of the valve body during assembly, which permits overpressure protection to be blowout-proof. An internal side surface of a valve seat of the valve base, and a valve bore of the valve body through which the valve stem moves, have matched diameters to reduce hysteresis effects.
