    Abstract: A cryogenic fluid delivery system includes a tank adapted to contain a supply of cryogenic liquid, with the tank including a head space adapted to contain a vapor above the cryogenic liquid stored in the tank. A liquid withdrawal line is adapted to communicate with cryogenic liquid stored in the tank. A vaporizer has an inlet that is in communication with the liquid withdrawal line and an outlet that is in communication with a vapor delivery line. A pressure building circuit is in communication with the vapor delivery line and the head space of the tank. The pressure building circuit includes a flow inducing device and a control system for activating the flow inducing device when a pressure within the head space of the tank drops below a predetermined minimum pressure and/or when other conditions exist.

    Abstract: A nozzle includes a nozzle bayonet with a warm seal positioned at a distal end and a nose seal positioned at a proximal end so that a distal passage is defined between the warm and nose seals. The nozzle also includes a nozzle poppet valve. Purge and vent lines are in fluid communication with the distal passage. A receptacle includes a receptacle poppet valve, a receptacle inner tube and a receptacle outer tube with a receptacle insulation space defined therebetween. A coupling space is defined between an outer casing and the receptacle outer tube. The receptacle coupling space receives the nozzle bayonet. The receptacle sequentially engages the warm seal and the nose seal of the nozzle during insertion of the nozzle bayonet into the receptacle coupling space with the nozzle and receptacle poppets engaging to open the nozzle and receptacle poppet valves when the nozzle bayonet is fully inserted into the receptacle coupling space.

    Abstract: A body structure has an inlet port that receives fluid, a first outlet port that connects to a top-fill line of a cryogenic tank, a second outlet port that connects to a bottom-fill line of a cryogenic tank and a slider tube cylinder. A cylinder housing connects to the body structure and has a pressure comparison cylinder with upper and lower volumes, with the latter in fluid communication with a cryogenic tank. A piston having a piston shaft slides within the pressure comparison cylinder. A pressure regulator is in fluid communication with the upper volume and the slider tube cylinder. A slider tube is connected to the piston shaft and slides within the slider tube cylinder. The slider tube cylinder selectively directs fluid to a top-fill line through the first outlet port or to a bottom-fill line through the second outlet port.
