Abstract: A plate-type heat exchanger is described comprising a stack of heat exchanger plates (2b) forming a first flow path and a second flow path, wherein each heat exchanger plate (2b) comprises an opening (7b) in an opening area (8b), the opening area (8b) being connected to one of the two flow paths and sealed against the other of the two flow paths by means of a gasket arrangement (11b). Such a plate-type heat exchanger should be suitable for high pressures without increasing the risk of leakages. To this end a support element (15) is arranged in the sealed opening area (8b).

Abstract: An expansion valve (1) is described to include a housing (2) having in inlet port (3) and an outlet port (4), a valve seat (5) arranged between the inlet port (3) and the outlet port (4), a valve element (6) movable over an operating stroke between a closed position at the valve seat (5) and an opened position away from the valve seat (5), and an actuator (7), wherein the actuator (7) has an electric rotary motor (8) acting on the valve element (5) by means of a threaded spindle (10) and a nut (9), wherein one of spindle (10) and nut (9) is rotatably driven by the motor (8) and the other one is rotatably fixed. Such an expansion valve should have the possibility for a simple assembly. To this end, in a disassembled condition of housing (2) and actuator (7), the actuator (7) has a mounting stroke which is at least two times the operating stroke, wherein the mounting stoke extends the operating stroke.
