Embodiment Construction
[0044] Apparatus for handling pressurized fluids 2 in Figure 1 to Figure 11 shown in . The device comprises a terminal 4 forming a source of pressurized fluid and a gun 62 forming a first part of a coupling 6, the complementary part 64 of which is mounted on a motor vehicle 8 comprising an on-board tank 82 for storing pressurized fluid , and the vehicle fuel tank can be coupled with the gun 62. Line 9 connects terminal 4 with gun 62 . The safety circuit breaker 10 is inserted along the line 9 and divides the line between a first upstream section 92 extending between the terminal 4 and the circuit breaker 10 and a second downstream section 94 which A section extends between said circuit breaker 10 and the gun 62 .
[0045] For the sake of clarity of the drawings, only in the figure 1 with Figure 9 Components 4 and 62 of device 2 are shown respectively in .
[0046] The circuit breaker 10 comprises a male element 100 and a female element 200 .
[0047] The male element ...

Provided are a circuit breaker and a handling installation for pressurized fluid including such a circuit breaker. The circuit breaker includes a male element and a female element. The male element includes a male body defining a first inner pipe and provided with a member for closing off the front end of the first pipe, along the fitting axis, of at least one first radial passage, of a movable valve and a locking notch arranged on the male body. The female element includes a female body defining a second inner pipe and provided with at least one radial passage, a movable valve and several locking members movable transversely with respect to the fitting axis, between a first radial position, for the axial locking of the male and female bodies in the coupled configuration, and a second radial position, where the locking members free the passage of the male body in the female body. In the coupled configuration, the radial passages are in communication, while sealing gaskets respectivelycooperate radially with the male and female bodies. A resilient return ring is mounted on the female body and surrounds the locking members. This ring resiliently returns the locking members toward their first radial position in the coupled configuration and is deformed radially, and resiliently, by the locking members during their movement, from their first radial position toward their second radial position.
Description
technical field [0001] The invention relates to a so-called "safety" circuit breaker for use in equipment for the treatment of pressurized fluids, such as equipment for filling motor vehicle fuel tanks with pressurized hydrogen. Background technique [0002] In order to prevent the time required to fill motor vehicle tanks with pressurized hydrogen from being too long, it is known to use high filling pressures which can be as high as 875 bar. Depending on this pressure level, the connection between the hydrogen source and the vehicle tank must be tight. [0003] During filling it is not possible to rule out untimely movements of the fuel tank of the motor vehicle, which movements can be caused by poor fixing of the vehicle or incorrect handling by the user. This movement must not cause alteration or exposure to the outside world of the lines connecting the source of pressurized hydrogen to the vehicle's fuel tank. [0004] Similar problems arise in other equipment used to ...
