The present invention relates to a multi-coupling device of the plate type for the simultaneous connection of a plurality of hydraulic, electric and pneumatic lines through quick couplings. The device according to the present invention is characterized in that it comprises bayonet coupling means which allow the coupling of the two plates by means of the relative sliding of the mobile plate with respect to the fixed plate. By virtue of the presence of a dedicated hydraulic circuit which connects the female couplings of the fixed plate to one another, the multi-coupling device according to the present invention allows to separate the step of coupling of the plates from the step of hydraulic connection of the male and female couplings.

The invention relates to a device for connecting feed lines, comprising: first electrical connector elements which can each be connected to a power supply, and first fluid connection elements which can be connected to a working fluid source, all of said elements being grouped together in a fixed manner in a first stationary connector; a power feed line, a working fluid feed line; and a second fluid connection element coupled to a first end of a flexible tube and second electrical connector elements, grouped together in a fixed manner in a first movable connector. According to the invention, at least first end segments of the second electrical connector elements and of the flexible tube are disposed inside an elastically flexible hose that is connected to the first movable connector.

A fastening structure includes a circular sleeve and a coupling member. One end of the circular sleeve has a receiving trough. A bottom of the receiving trough is provided with a first magnetic member. A wall of the receiving trough is provided with a protruding post. At least one guide groove is formed on an outer wall of one end of the coupling member. One end of the guide groove is an open axial groove having an opening. Another end of the guide groove is a closed axial groove having a stop end. The guide groove has a transverse groove between the open axial groove and the closed axial groove. Another end of the coupling member is a pivot end that has a central passage extending inwardly. A second magnetic member is disposed in the central passage. The first and second magnetic members have repulsive magnetic poles.

A disconnect fitting adapted for use with a phase changing composition including a fitting base having a first fitting base end, a second fitting base end and a fitting base opening therebetween, a pin capture disposed within the fitting base opening, a displaceable pin secured within the pin capture, a fitting socket having a first fitting socket end, a second fitting socket end, a fitting socket opening therebetween, the second fitting socket end secured to the second fitting base end, and a valve at least partially disposed within the fitting socket opening. When the displaceable pin is in an unloaded condition, the displaceable pin extends in a direction of the second fitting base end, and when the displaceable pin is in a loaded condition, the displaceable pin is compressed in a direction of the first fitting base end. The pin capture permits passage of the phase changing composition through the fitting base opening when the displaceable pin is in the unloaded condition or the loaded condition. The disconnect fitting permits a secure connection of the fitting base and the fitting socket regardless of the state the material when the base and socket are disconnected.

A coupling assembly includes a locking collar, a gasket, and a retaining sleeve. The locking collar includes a body and external threads. The external threads are formed on an outer circumferential surface of the body. The gasket is positioned between first and second pipes, and the locking collar. The retaining sleeve includes internal threads formed in an inner circumferential surface of the retaining sleeve. Each internal thread is configured to receive a respective external thread of the locking collar. The retaining sleeve is rotatable between an unlocked position in which the gasket seal is disengaged from the locking collar and the first and second pipes, and a locked position in which the external threads and the internal threads cooperate to move the retaining sleeve axially along the locking collar so that the gasket seal is engaged with the locking collar and the first and second pipes.
