  • Patent number: 9506681
    Abstract: The invention relates to a device and a method for generating a positive pressure in a tank for liquefied gas on a refrigerated vehicle with an evaporator for the liquefied gas, in conjunction with which the evaporator is connected in a fluid-conducting fashion to the tank via a line for liquefied gas, and in conjunction with which a valve is arranged in the line, comprising the following method steps: opening the valve so that liquefied gas exits from the tank and into the line; closing the valve in such a way that a quantity of the liquefied gas remains in the line and is able to flow back into the tank; heating the quantity in the line. The invention also relates to a method for the supply of liquefied gas, and a device for generating a positive pressure in a tank for liquefied gas in a cooling system, in conjunction with which the method according to the invention for generating a pressure is utilized.

  • Publication number: 20140216601
    Abstract: The present invention relates to a method and a device for refilling a stationary storage tank with a subcooled cryogenically liquefied gas from a tanker. A subcooler, comprising a cooling bath and connected between the tanker and an inlet of the storage tank, is filled with the liquefied gas from the tanker up to a filling level and cooled to a bath temperature. The storage tank is subsequently refilled with the liquefied gas from the tanker by the liquefied gas being pumped through a heat exchanger in the cooling bath of the subcooler into the storage tank by using a delivery pump, during which it is cooled to the bath temperature of the cooling bath. After the end of the filling process, the subcooler is no longer supplied with liquefied gas and therefore heats up.

  • Publication number: 20110239670
    Abstract: A method for managing access to a confined space which is cooled by the direct injection of a cryogenic fluid, comprising at least one system for closing the confined space, which can prevent access to said confined space and can be opened/closed to a variable and controllable degree, and a data acquisition and processing device. The device can: control the open or closed state of the closure system; set and control the degree to which the closure system is open/closed; ensure that a time delay (TP) is respected every time the closure system is closed, after which time delay the injection of cryogenic fluid into the space resumes; and, at the request of a user, implement the cycle for opening the closure system. The device determines the time that has elapsed (TE) in the closed position since the last closure cycle of the closure system and compares TE to TP. If TE=TP the device immediately authorizes the opening of the closure system.

  • Publication number: 20090277188
    Abstract: The invention relates to a heat exchanger for a mobile refrigerated vehicle having a tank for liquefied gas comprising a pipe for accepting a flow of a liquefied gas and for the evaporation of at least one part of the liquefied gas, in conjunction with which the pipe, at least in sections, exhibits a longitudinal axis, and the heat exchanger comprises an inlet side for liquefied gas and an outlet side for at least partially evaporated gas, and in conjunction with which the outlet side is connected to an exhaust pipe in such a way as to permit a flow, in conjunction with which the pipe exhibits elements in its interior for the purpose of generating turbulences in the flow or a radial phase separation. The invention is characterized in that, with the help of the elements, the thickness of a gas interface layer on a wall of the pipe, which occurs as a result of vaporization of the gas, is reduced considerably, whereby the efficiency of the heat exchanger is increased considerably.

  • Patent number: 4033434
    Abstract: A pair of brake levers each having a brake shoe thereon acting in opposite directions against a brake drum have one end pivotally mounted and the other end of one brake lever is pivotally connected to a pivotally mounted operating lever. A rod is pivotally connected between the other brake lever and the operating lever. The operating lever is moved in the non-braking direction by an actuator and a spring pivots the operating lever in the other direction to apply the brake shoes. The end of the rod pivotally connected to the operating lever has a uni-directional drive thereon to adjust the effective length of the rod only when the operating lever is moved in the non-braking direction to compensate for wear of the brake shoes.
