An object is to propose a fluid handling device for liquid hydrogen that prevents evaporation of liquid hydrogen, and moreover affords excellent heat insulation without liquefying oxygen in the vicinity. In a fluid handling device for liquid hydrogen, piping sections (1) have a heat insulation structure, a swivel joint section (2) is configured with helium gas sealed into a boundary relative-rotation section (6) between an outer ring section (3) and an inner ring section (4) with a bearing section (5) interposed, and moreover, between an outside-air-contacting wall section (7) that is in contact with the outside air and a liquid-hydrogen-contacting wall section (8) that is in contact with liquid hydrogen, a vacuum section (9) extends in the axial direction and moreover a heat-conducting extended path section (10) is provided with one end connected to the outside-air-contacting wall section (7) and the other end connected to the liquid-hydrogen-contacting wall section (8), extending the heat conduction distance between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8), and reducing heat conductivity between the outside-air-contacting wall section (7) and the liquid-hydrogen-contacting wall section (8).

Disclosed is a valve apparatus of a urea tank for a vehicle, the valve apparatus configured such that a urea solution injection pipe is flexibly bent and has a float so that a urea injection valve provided at the urea solution injection pipe is prevented from being immersed in the urea solution in the urea tank. Thus, the urea solution can be prevented from being damaged upon freezing in a winter season. Further, when a urea solution is injected, the urea solution injection pipe is straightened by flow pressure of the urea solution such that the float is forced to be immersed in the urea solution in the urea tank, and accordingly the urea solution injection valve is immersed therein. Thus, the urea solution can be efficiently injected into the urea tank.

A fuel transfer system for use with a motor vehicle includes a stationary module configured for permanent installation in the motor vehicle and a portable module configured for a detachable connection to the stationary module. The stationary module has a fuel fitting arranged in fluid communication with the fuel line between the fuel sending unit and the engine, a first fuel conduit connected to the fuel fitting and to a first transfer connector. A first normally closed valve is arranged in the first transfer connector. The first transfer connector is configured to be secured to a motor vehicle, for example next to a fill neck behind a filler door of the vehicle. The portable module has a second fuel conduit having a second transfer connector on one of two ends and a fueling nozzle connected to the other one of the two ends of the second fuel conduit.

An inventive boom arm for a concrete-distributing boom. The boom arm has an elongate box-profile support formed from two flanges and two webs connecting the flanges laterally. The boom arm has first and second articulation points spaced apart in the longitudinal direction of the boom arm. A first flange opening is disposed at the first articulation point and a second flange opening is disposed at the second articulation point. A sealing-partition seals a cavity region of the box-profile support at least in a region of the first and second flange openings. The sealing partition can be provided in the form of a plate that continuously spans the cavity region between the first and second articulation points and is connected laterally to the webs. The first articulation point is located at the end of the boom arm and is arranged within the cavity region and is covered by the partition plate.
