Abstract (en)

[origin: WO2010006729A2] The invention relates to an expansion valve for regulating the mass flow rate by generating a pressure difference on the expansion valve of a refrigeration or heating cycle. Said expansion valve comprises a base (31) having a through-hole (32) that is surrounded by a valve seat (33), and a valve element (34) which closes the through-hole (32) and rests within the valve seat (33) in a closed position and can be moved relative to the valve seat (33) in the opening direction on the base (31). The base (31) is designed to be inserted into a bore section (29) of an attachment point (26, 27) of a connection (21) of an internal heat exchanger (14) or into a connection (21) of a pipe in the refrigeration or heating cycle. The outer circumference (46) of the base (31) has a fastening section (47) that is releasably fastened to the attachment point (26, 27) of the connection (21) by means of a complementary fastening section (48).
