Embodiment Construction

[0046] Figure 1 to Figure 8 A connector 1 according to the invention is shown.

[0047] This connector 1 comprises a connector element 2 and a connection device 10 also according to the invention. The element 2 is configured as a male connector end, while the device 10 is configured as a female connector end adapted to receive the element 2 . The device 10 is intended to be connected to a first line, and the element 2 is intended to be connected to the connection device 10 and to a second line, these lines not being shown in the figure 1 -8 shown. figure 1 , 2 and 7 show connector 1 in a detached state, in image 3 is in the join period, in the Figure 4 , 5 and 8 are in the connection state.

[0048] The element 2 and the device 10 are two components of the connector 1, which is suitable for high pressure and high temperature (up to 450°C) or extremely low temperature (for example up to -250°C) when the connector 1 is in the coupled state. convey gaseous and / or liquid ...

Abstract

The invention relates to a connecting device and a connector comprising the device. The connector is adapted for transmitting pressurized fluids, comprising a pipe end delimiting an inner flow channelfor a fluid, an end body including an inner cavity isolated from the inner flow channel, and displacement means for moving the pipe in the body between an unlocked configuration and a locked configuration. These displacement means comprise a pivot, an off-centered member, a connecting rod and a rear housing formed in the body, defining a first articulation diameter between the pivot and the off-centered member around a first axis, a second articulation diameter between the off-centered member and the connecting rod member around a second axis, and a third articulation diameter between the connecting rod and the rear housing around a third axis. The three axes are separate and parallel to a transverse direction transverse of the device. The distance between the first and second axes is smaller than the half-sum of the first and second diameters. The distance between the second and third axes is smaller than the half-sum of the second and third diameters. The translatable pivot is capable of pushing the pipe back in a forward direction.

Description

technical field [0001] The invention relates to a connecting device. The invention also relates to a connector comprising the device. [0002] The field of the invention is that of a connector suitable for the communication of fluids at high pressures and high or very low temperatures, which require maximum safety and tightness of the metal parts employed. Advantageously, this sealing is achieved by metal-to-metal contact without the need to use a seal made of polymeric material. The invention is also suitable for special applications in the field of cryogenic technology. Background technique [0003] GB-A-163,053 describes a connecting device between two conduits. The first conduit is screwed into the main coupling element having a first frusto-conical surface. The second conduit is threaded into a coupling ring provided with a second frusto-conical surface and slide-fitted into the main element. The device also includes a cam lever mounted on the coupling element, int...
