Abstract:
Ventil (1) mit einem Ventilgehäuse (2), in dem ein Ventilsitz (5) und ein Einlass (3) und ein Auslass (4) angeordnet sind. Das Ventilelement (6) ist dabei in einem Deckel (9) des Ventilgehäuses angeordnet und auf seiner dem Ventilsitz (5) zugewandten Seite mit einer Stützplatte (10) befestigt. Um das Verlieren einzelner Bauteile des Ventils beim Abnehmen des Deckels zu verhindern, ist die Stützplatte im Deckel befestigt.
Abstract:
A method to manufacture a valve using metal injection moulding is disclosed. The valve housing (2) comprises a welding cap (14) for welding the upper part (5) of the valve to the valve housing (2). The welding cap (14) is placed so the upper part (5) can be welded to the housing (2) without damaging the inner cavity (10) of the housing. There is a gap between the welding cap (14) and the inner liner (15) so the heat from the welding do not damage the inner liner (15) allowing the inner parts of the valve to move freely.
Abstract:
The invention relates to a solenoid valve (1) with a housing (2) as well as an inlet (3) and an outlet (6), wherein the solenoid valve further comprises a valve element and an orifice (14), wherein the orifice comprises an orifice inlet (15) and an orifice outlet (16). In order to increase the maximum operating pressure differential of the solenoid valve the orifice is provided in a membrane (12) and the orifice has a diffuser characteristic in a direction from the orifice inlet to the orifice outlet.
Abstract:
A refrigerant exchange arrangement is claimed with a first oil-trapping chamber (10) and a second oil-trapping chamber (11). A refrigerant exchange arrangement of simple construction is to be realized. For this purpose, the second oil-trapping chamber (11) is disposed within the first oil-trapping chamber.

Abstract:
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).
