摘要:
Connection device (10) for fluid circuits, the device (10) being arranged to hydraulically connect two adjacent circuit sections (C, C') and, if necessary, to allow disconnection of the two circuit sections (C, C') under load without causing fluid losses from the circuit, the device (10) comprises moreover two thermal expansion valves (12, 12') releasably connected directly to each other, each valve (12, 12') being configured to be mounted to an end of a respective circuit section (C, C') and being shiftable between an open position and a closed position, in which it allows and prevents fluid flow through the device (10), respectively, depending on the fluid temperature.

摘要:
The invention relates to a releasing element (15) used in a security system (13) for coupling devices, in particular for breaking couplings (10) consisting of two coupling halves (11, 12) removably connected by means of a security element (14). Said invention is characterised in that the releasing element (15) makes it possible to contactlessly fixing the security element (14) to the coupling halves (11, 12). The invention also relates to a security system which makes it possible to connect and disconnect the coupling halves (11, 12) and comprises the security element (14) provided with at least two lever elements (29) and the releasing element according to claims 1 to 11. Said invention is characterised in that the lever elements (29) are constructed and arranged in such a way that the releasing element (15) is hold and maintained exclusively by said lever elements (29). A breaking coupling provided with the inventive security system is also disclosed.
