摘要： 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).

摘要： The invention relates to an insert (1) for a thermostatic expansion valve as a thermostatic expansion valve (2) comprising such an insert and to a method of assembling such a thermostatic expansion valve (2). The insert (1) comprises an expansion valve element (3) and an expansion valve seat (4). The expansion valve element (3) is held inside the insert (1) by a biasing member (5), wherein the insert (1) is structured and arranged to be inserted into a valve housing (8). The task of the invention is to provide an insert for a thermostatic expansion valve that allows a simple assembly of the valve and also provides an improved functionality. The task is solved in that the insert (1) further comprises a control valve (12), wherein the control valve (12) is located in the same flow path through the insert (1) as the expansion valve seat (4).

摘要： The invention relates to a capsule for a valve as well as to a valve comprising such a capsule. The task of the present invention is to provide a valve in which tight tolerances for construction can be achieved and the assembly of the valve is simplified. According to the present invention the above task is solved by a capsule (1) for a valve comprising at least one diaphragm (2), a valve seat (3), a capsule inlet (5) and a capsule outlet (6). The valve seat (3) is openable and closable to permit or stop a fluid flow from the capsule inlet (5) to the capsule outlet (6). The above task is also solved by a capsule (1) for a valve that comprises at least one diaphragm (2), a valve seat (3), a capsule inlet (5) and a capsule outlet (6), wherein the capsule (1) is structured and arranged to control the position of a pilot valve element external to the capsule (1). The above task is also solved by a valve (10) comprising a valve housing (15), wherein a capsule (1) of the above kind is arranged in the valve housing (15).
