The invention relates to a device (1) for controlling a flow rate and expanding a fluid in a fluid circuit. The device (1) is formed by a closure (2) and a valve element (6) arranged inside the closure (2). A valve element (6), which is arranged to be movable in a linear movement (6a) relative to the enclosure (2) in the direction of the longitudinal axis, has a sealing surface (11a) and a control region (16), which is formed at a first end face of the valve element (6) and is arranged adjacent to the sealing surface (11a) in the axial direction. The sealing surface (11a) is formed in the form of a side surface of a straight circular cylindrical member having a constant outer diameter. The outer diameter of the surface of the control region (16) corresponds to the outer diameter of the sealing surface (11a). Furthermore, the control region (16) has a through-flow opening (14) and at least one control opening (15). The valve element (6) is formed with a substantially hollow cylindrical wall in the control region (16). The invention also relates to a method for operating a device (1) for controlling a flow and expanding a fluid in a fluid circuit.

    本发明涉及一种用于在流体回路中控制流量并且使流体膨胀的装置(1)。装置(1)由封围件(2)和布置在封围件(2)的内部的阀元件(6)形成。布置成能够相对于封围件(2)沿纵向轴线的方向以线性运动(6a)的方式移动的阀元件(6)具有密封表面(11a)和控制区域(16),该控制区域形成在阀元件(6)的第一端部面处并且布置成在轴向方向上与密封表面(11a)邻近。密封表面(11a)形成为呈具有恒定外直径的直的圆形筒状件的侧表面的形式。控制区域(16)的表面的外直径与密封表面(11a)的外直径对应。此外,控制区域(16)具有通流孔口(14)和至少一个控制孔口(15)。阀元件(6)在控制区域(16)中形成有大致中空的圆筒形形状的壁。本发明还涉及一种用于操作用于在流体回路中控制流量并且使流体膨胀的装置(1)的方法。
