    Abstract: The invention relates to a valve (1, 1a), in particular an expansion valve, for controlling fluid flow, having a valve central housing (10, 10a) having a first and a second opening (12, 12a, 14, 14a) and a valve element (20, 20a) which has a rotationally symmetrical outline and is arranged rotatably within the valve element housing (10, 10a). According to the invention, the valve element (20, 20a) has a cut-out, wherein the cut-out (30, 30a, 30b, 30c) has a variable dimension, and a sub region (32, 32a) of the cutout (30, 30a, 30b, 30c) is formed continuously through the valve element (20, 20a).

    Abstract: Equipping engine cooling fans with flaps, in particular ram-air flaps, which are opened by the relative wind and can close again by means of gravity at a vehicle standstill, is known. Until know, it has been common to install such ram-air flaps manually on a frame of the engine cooling fan. However, all of said embodiment concepts require complex motion guidance during the installation in/on the frame. The invention relates to a method for producing a frame (1) for an engine cooling fan of a motor vehicle in order to provide economical automation, the frame being equipped with a flap (5), in particular ram-air flap, and produced by means of injection molding in a tool (16), wherein an articulated connection of the flap (5) to the frame (1) is provided in a joint production step for the frame (1), in which the flap (5) is first prepositioned in the tool (16) for the production of the frame (1) and then provided cavities (10) of the flap (5) are also filled during the production of the frame (1), which cavities form corresponding bearing points (11) for the flap (5) on the frame (1) after the solidification of the plastic and thus enable a movable connection of the flap (5) to the frame (1). The invention is intended for frames having ram-air flaps for engine cooling fans of motor vehicles.

    Abstract translation: 将发动机冷却风扇设置为具有襟翼,特别是由相对风打开并且可以在车辆停止时通过重力再次关闭的襟翼空气襟翼。 直到知道,通常将这种压缩空气襟翼手动安装在发动机冷却风扇的框架上。 然而,所有实施例的概念都需要在安装在框架内/上的复杂的运动引导。 本发明涉及一种用于生产用于机动车辆的发动机冷却风扇的框架(1)的方法,以便提供经济的自动化,该框架配备有翼片(5),特别是冲压空气翼片,并由 在工具(16)中注射成型的装置,其中,在所述框架(1)的接合制造步骤中,所述翼片(5)与所述框架(1)的铰接连接被设置在所述框架(1)中,其中所述翼片 在框架(1)的制造过程中,将预置在工具(16)中用于生产框架(1)并且然后提供翼片(5)的空腔(10)也被填充,该空腔形成相应的支承点(11 ),用于在塑料固化之后在框架(1)上的翼片(5),从而使得翼片(5)与框架(1)的可动连接。 本发明适用于具有用于机动车辆的发动机冷却风扇的压缩空气襟翼的框架。
