    摘要： A cryogenic fluid delivery system includes a main tank system with a main tank adapted to contain a first supply of cryogenic liquid, and reserve tank system with reserve tank adapted to contain a second supply of cryogenic liquid. A pressure building circuit is adapted to delivery vapor to the head space of the main tank to build pressure in the main tank and a fuel delivery line supplies cryogenic fuel from either the main tank or the reserve tank to a use device. The reserve tank stores saturated cryogenic fuel that is delivered to the use device via the fuel delivery line while the cryogenic liquid in the main tank is being saturated. The fluid delivery system automatically switches to delivering cryogenic fuel from the main tank to the use device via the fuel delivery line upon saturation of the cryogenic liquid in the main tank.

    摘要： A body structure includes an inlet port that receives fluid from a delivery device, a top-fill outlet port that connects to a top-fill line in communication with a cryogenic tank, a bottom-fill port that connects to a bottom-fill line in communication with a cryogenic tank and a slider tube cylinder. A cylinder housing is connected to the body structure and has a pressure comparison cylinder with an upper volume and a lower volume, with the latter in fluid communication with a cryogenic tank. A piston slides within the pressure comparison cylinder and a piston shaft is connected to the piston. A pressure regulator is in fluid communication with the upper volume of the pressure comparison cylinder 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 directs fluid to a top-fill line through the top-fill outlet port when a pressure in the lower volume exceeds a pressure setpoint and fluid to a bottom-fill line through the bottom-fill outlet port when the pressure in the lower volume is below a pressure setpoint. An over-pressure member is positioned in the upper volume of the pressure comparison cylinder. The piston contacts the over-pressure member as the piston slides upward in the pressure comparison cylinder.

    摘要： 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.

    摘要： A system for transferring cryogenic fluid from a dispensing tank to a receiving tank is disclosed. The dispensing tank stores a supply of cryogenic liquid with a dispensing tank headspace above the liquid. A compressor has an inlet connected to the headspace of a receiving tank and an outlet connected to the headspace of the dispensing tank. A liquid transfer line is in fluid communication with the liquid side of the dispensing tank and the receiving tank. Cryogenic liquid is transferred from the dispensing tank to the receiving tank when the compressor is activated so as to transfer vapor from the headspace of the receiving tank to the headspace of the dispensing tank to create a pressure differential between the dispensing and receiving tanks.
