液压门致动装置的阀
摘要：
本发明涉及用于液压门致动装置的阀(1)。所述门致动装置设置用于打开和/或关闭所连接的门，且其具有壳体(13)。所述阀(1)设置于门致动装置的壳体(13)内，用以影响液压流体(H)在门致动装置中的流动。所述阀(1)包括衬套(2)以及滑动件(3)，该滑动件(3)被引导以便能在衬套(2)中纵向位移，并且其借助于复位弹簧(4)而在衬套(2)的纵轴线(L)的方向上被预加张力。所述滑动件(3)具有止推面(5)，由于复位弹簧(4)的作用，该止推面接触设定在衬套(2)上的相对边缘(6)，且由此阻塞液压流体(H)的流动，并且滑动件(3)设定成从外侧机械地作用，以抵抗复位弹簧(4)的作用。本发明还涉及配备有这种阀的门致动装置，该装置设置用于液压地打开和/关闭所连接的门，且其具有壳体(13)和液压回路，当门致动装置执行打开运动或关闭运动时，则液压流体被迫移动通过液压回路。所述阀(1)被整合到门致动装置的液压回路中，使得由于复位弹簧(4)的作用，其阻塞液压流体(H)在液压回路中的流动。所述滑动件(3)在门致动装置的打开运动或关闭运动期间借助于门致动装置的致动装置(24)而受到机械地作用，且因而被推动而在复位弹簧(4)的方向上被迫远离所述相对边缘(6)。
摘要（英）：

The invention relates to a valve (1) for a hydraulic door actuating device. The door actuating device is set up for opening and/or closing a connected door, and comprises a housing (13). The valve (1) is set up in the housing (13) of the door actuating device for influencing a flow of hydraulic fluid (H) in the door actuating device. The valve (1) comprises a sleeve (2) and a slide (3) longitudinally displaceably guided in the sleeve (2) and pretensioned by a return spring (4) in the direction of a longitudinal axis (L) of the sleeve (2). The slide (3) comprises a thrust surface (5) contacting a counter edge (6) implemented on the sleeve (2) due to the action of the return spring (4), and thereby blocks the flow of hydraulic fluid (H), and is designed for being acted on mechanically and externally against the action of the return spring (4). The invention further relates to a door actuating device having such a valve, set up for hydraulically opening and/or closing a connected door, and a housing (13) and a hydraulic circuit, through which the hydraulic fluid is forced when the door actuating device performs an opening or closing motion. The valve (1) is integrated in the hydraulic circuit of the door actuating device, such that it blocks the flow of hydraulic fluid (H) in the hydraulic circuit due to the action of the return spring (4). The slide (3) is acted on mechanically by an actuating device (24) of the door actuating device during the opening or closing motion thereof, and is thereby forced away from the counter edge (6) in the direction of the return spring (4).
