Abstract:
1. A coupling unit ( 16 ) for connecting refrigerant lines ( 11 ) of a refrigerant circuit ( 10 ), in particular for cooling a vehicle drive module, the coupling unit ( 16 ) including an expansion valve ( 20 ) accommodated in the coupling unit ( 16 ), the expansion valve ( 20 ) separating the refrigerant circuit ( 10 ) into first and second sub-areas ( 30 , 32 ), the coupling unit ( 16 ) being connected directly to a refrigerant feed ( 25 ) and a refrigerant return ( 27 ) for an evaporator ( 26 ), the coupling unit ( 16 ) comprising coupling connections ( 36 , 38 ) for the refrigerant feed ( 25 ) and the refrigerant return ( 27 ) which are detachably connected to the expansion valve ( 20 ) via a common fastening device ( 44 ), and with the common fastening device ( 44 ) having at least one fastening element ( 48 ) that is accessible for connecting and disconnecting from a side of the expansion valve ( 20 ) that faces away from the coupling connections ( 36 , 38 ), wherein the coupling connections ( 36 , 38 ) are axially fixed through a lateral indentation ( 50 ) and a lateral projection ( 52 ) of a pressing part ( 46 ) of the common fastening device ( 44 ).
