Embodiment Construction
[0033] in Figure 1 to Figure 3 , The valve 1 according to the first embodiment of the invention is shown in a simplified manner, respectively, wherein according to the illustration, only the upper half is selected and shown in the figure, that is, the half of the valve visible above the longitudinal axis L , Represented by valve 1 below.
[0034] Accordingly, the valve 1 has a bush 2 in which the slide 3 is guided. In this case, the slider 3 is prestressed by means of the return spring 4 in a direction parallel to the longitudinal axis L of the bush 2 and is thereby pushed against the opposite edge 6 which is arranged on the bush 2Inside and located at bushing 2.
[0035] To this end, the slider 3 has a stop surface 5, according to image 3 At the indicated angle α, the stop surface 5 is arranged to be inclined relative to the longitudinal axis L. Due to the action of the return spring 4, the stop surface 5 of the sliding member 3 abuts against the opposite edge 6 in a fluid-ti...

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).
Description
Technical field [0001] The present invention relates to a valve of a hydraulic door actuator device according to the preamble of claim 1, that is, a valve of a hydraulic door closer, which swings the valve of the door leaf operator accordingly. Background technique [0002] According to the document DE 10 2005 030 696 A1, for example, a hydraulic door operator is known, in which a magnetic valve is used to close the door in the event of a fire. However, this would require the provision of sensing technology to detect the opening angle of the door, as well as provision of trigger electronics to activate the magnetic valve, which is expensive and results in a more complicated structure. [0003] Moreover, in such a door actuation device, it is necessary to lock the door in a certain position in part. In particular, in the double-door swing door system, as long as the inactive door leaves are still open so that when the movable door leaves are closed, the closing sequence (the inacti...
