摘要： An expansion valve (1) comprising an inlet opening and at least two outlet openings (5) is disclosed. The inlet opening is adapted to receive fluid medium in a liquid state, and the outlet openings (5) are adapted to deliver fluid medium in an at least partly gaseous state. The expansion valve (1) further comprises a diaphragm (6), and at least two valve seats (4), each valve seat (4) being fluidly connected to one of the outlet openings (5). Each of the valve seats (4) forms a valve in combination with the diaphragm (6), the position of the diaphragm (6) thereby simultaneously defining an opening degree of each of the valves. A well defined distribution of fluid flow towards each of the outlet openings (5) is easily defined by movements of the diaphragm (6). The distribution takes place before or during expansion of the fluid medium. The expansion valve (1) may be arranged in an refrigerant path of a refrigeration system.

摘要翻译：公开了一种包括入口和至少两个出口（5）的膨胀阀（1）。入口开口适于接收处于液体状态的流体介质，并且出口开口（5）适于以至少部分气态的状态输送流体介质。膨胀阀（1）还包括隔膜（6）和至少两个阀座（4），每个阀座（4）流体地连接到一个出口（5）。每个阀座（4）与隔膜（6）组合形成阀，隔膜（6）的位置由此同时限定每个阀的开度。流体流向每个出口（5）的明确分布很容易通过隔膜（6）的运动来限定。分布发生在流体介质膨胀之前或期间。膨胀阀（1）可以布置在制冷系统的制冷剂路径中。

摘要： An expansion valve (1) comprising an inlet opening (2) and a distributor (4) being arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths (3). At least two outlet openings (3) are adapted to deliver fluid in an at least partially gaseous state, and each outlet opening is fluidly connected to one of the parallel flow paths. A first valve part (7) and a second valve part (5) are arranged movably relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines the opening degree of the expansion valve. Since the distributor (4) forms part of the expansion valve, it distributes the fluid medium to the parallel flow paths prior to or during expansion of the fluid medium, i.e. while the fluid medium is in a substantially liquid state. This makes it easier to control the distribution of fluid medium to the parallel flow paths in a uniform manner.

摘要： An expansion valve (1) is disclosed which comprises an inlet opening (2), at least one outlet opening (3) and first and second valve parts. The inlet opening (2) is adapted to receive fluid medium in a liquid state. The outlet opening(s) (3) is/are adapted to deliver fluid medium in an at least partly gaseous state to a flow path. The valve parts are arranged movable relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines a fluid flow between the inlet opening (2) and the outlet opening(s) (3). During normal operation, a resulting force acts upon the first valve part and/or the second valve part to press the first and second valve parts towards each other. The expansion valve (1) comprises means for reducing the resulting force acting upon the valve part(s). Thereby the valve parts can easier be moved relative to each other, and the force required in order to operate the valve (1) is thereby reduced.

摘要： An expansion valve comprising an inlet opening and a distributor being arranged to distribute fluid medium received from the inlet opening to at least two parallel flow paths. At least two outlet openings are adapted to deliver fluid in an at least partially gaseous state, and each outlet opening is fluidly connected to one of the parallel flow paths. A first valve part and a second valve part are arranged movably relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines the opening degree of the expansion valve. Since the distributor forms part of the expansion valve, it distributes the fluid medium to the parallel flow paths prior to or during expansion of the fluid medium, i.e. while the fluid medium is in a substantially liquid state. This makes it easier to control the distribution of fluid medium to the parallel flow paths in a uniform manner.
摘要翻译：膨胀阀包括入口开口和分配器，其布置成将从入口开口接收的流体介质分配到至少两个平行的流动路径。至少两个出口开口适于以至少部分气态的状态输送流体，并且每个出口开口流体地连接到平行流路之一。第一阀部分和第二阀部分以这样的方式相对于彼此可移动地布置，使得第一阀部分和第二阀部分的相互位置确定膨胀阀的开度。由于分配器形成膨胀阀的一部分，所以在流体介质膨胀之前或期间，即当流体介质处于基本液态时，其将流体介质分配到平行流动路径。这使得更容易以均匀的方式控制流体介质到平行流动路径的分布。
