ELECTRIC POWER SYSTEM AND A METHOD FOR PROTECTING THE SAME
An electric power system includes a direct voltage rail system (101) and power converters (102-106) each transferring electric energy between the direct voltage rail system and a power source or a load. Each power converter includes a protection system (107) responsive to operation of the power converter outside a safe operating area of the power converter. Each power converter is connected to the direct voltage rail system via a protector element (108-112) for disconnecting the power converter if electric current through the protector element is outside an allowed range, and each power converter is connected to the power source or the load via a circuit breaker (113-117).

MOUNT FOR FLUIDICALLY CONNECTING A RECEIVER TO A REFRIGERANT CIRCUIT AND ASSEMBLY COMPRISING THE MOUNT, CHECK VALVE ELEMENTS AND AN EXPANSION VALVE INSERT
The present invention relates to a mount (1) for fluidically connecting a receiver (100) to a refrigerant circuit (R). The mount (1) comprises a first channel (2), a second channel (15), a third channel (14), a fourth channel (12) and a fifth channel (13). The first channel (2), the fourth channel (12) and the fifth channel (13) are configured to be receive respective check valve elements (101, 102, 103, 104). Further, the second channel (15) is configured to receive an expansion valve insert (107). When being equipped with respective valve elements and used as an assembly according to the invention, respective fluid channels (2, 12, 13, 14, 15) of the mount (1) are configured to be opened or closed depending on the direction of fluid flow, thereby allowing fluid to pass from a first port (3) to a second port (4), for example via the receiver (100), or vice versa. In particular to save manufacturing time and to reduce the number of brazings, the mount (1) is formed in one piece.

IMPROVED LATCHING ARRANGEMENT FOR A QUICK CONNECTING AND DISCONNECTING FLUID COUPLING
The invention relates to a quick connecting and disconnecting fluid coupling (1, 25) with a male (2, 22) and a female fluid connector (3, 23). The male fluid connector (2, 22) comprises a connection latching arrangement (12, 15), and a sleeve (7) that is rotatably arranged relative to the body (6) of the first fluid connector part (2, 22). The sleeve (7) can be positioned in a mechanically biased standby position, in which the sleeve (7) is mechanically biased in a rotational direction (20) using a mechanical biasing means (17). The mechanically biased standby position is maintained in an uncoupled state of the quick connecting and disconnecting pressurised fluid coupling (1, 25) using a holding device (8, 24). The standby position is released by applying a releasing axial force onto the sleeve (7), wherein the releasing axial force is directed opposite to the connecting direction (4) of the first fluid connector part (2, 22).

IMPROVED FLUID CONNECTOR FOR QUICK CONNECTING AND DISCONNECTING FLUID COUPLINGS
The invention relates to a fluid connector part (2, 3) for a quick connecting and disconnecting pressurised fluid coupling (1). The fluid connector part (2, 3) comprises a housing (8) with a first fluid valve arrangement (10) between a fluid tube or hose side (6, 7) and a connecting side (4, 5) of the fluid connector part (2, 3). The first fluid valve arrangement (10) comprises a fluid throughput orifice (21) and a first spool member (11). The first spool member (11) is movable between at least an opening position, in which fluid may pass through the first fluid valve arrangement (10), and a closing position, in which the fluid passage (21) through the first fluid valve arrangement (10) is blocked. The fluid connector part (2, 3) is designed and arranged in a way that the first spool member (11) is pushed into its closing position by a pressure differential over the first valve arrangement (2, 3). Further the first spool member (11) may also be moved into its closing position by means of an externally accessible handling device (27).
