Abstract:
A bulb (5) for a thermostatic expansion valve is provided, said bulb (5) comprising a chamber (7), said chamber (7) being located within a metallic casing of said bulb and being filled with a filling adapted to influence a valve element of said thermostatic expansion valve. Service of a temperature controlled valve connected to a bulb should be facilitated. To this end said bulb (5) comprises a connection geometry (10) adapted to be connected to a capillary member (6) and said casing being provided with a closed opening zone located within said connection geometry (10), said opening zone being adapted to be opened upon mounting a counterpart (15) to said connection geometry (10).
