    • The invention relates to a hydraulic directional magnetic valve, in particular a hydraulic 3/2 directional magnetic valve (1), comprising a valve housing (2); a valve chamber (3) integrated in the valve housing (2) and having a first valve seat bore (6) as a connection to a first line, in particular a pressure line (P), a second valve seat bore (7) as a connection to a second line, in particular a working line (A), and a free opening (8) to a third line, in particular a tank line (T); an electromagnet (4); and a valve lifter (5) movable by means of the electromagnet (4) and partially arranged in the valve chamber (3), wherein the valve lifter (5) comprises within the valve chamber (3) a first sealing face (9) facing the first valve seat bore (6) and a second sealing face (11) facing the second valve seat bore (7), so that either the first valve seat bore (6) or the second valve seat bore (7) can be closed. The valve lifter (5) extends out of the valve chamber (3) right through the second valve seat bore (7) to the electromagnet (4) and, when the second valve seat bore (7) is closed, due to a differential area ratio the valve lifter (5) is drawn into the second valve seat bore (7) by means of the pressure in the second line, in particular the working line (A).

    • The invention relates to a door closer (10), comprising a spring arrangement (14) which is tensed for opening the door and which provides the necessary closing moment for the door to close; and a gear mechanism (20 to 28) between the spring arrangement (14) and the door for influencing the force characteristic which changes through the opening angle of the door. The gear mechanism (20 to 28), which changes in its transmission ratio through the opening angle of the door has a first and a second toothed wheel (24, 28) which engage with each other and which are each formed by a circular gear ring. Said toothed wheels are mounted eccentrically in relation to their central points (42, 44), their axial distance being maintained. The first toothed wheel (28) is connected to an output shaft (30) and the second toothed wheel (24) is connected to a toothed wheel (22), coaxially in relation to its centre of rotation (38). Said toothed wheel (22) engages with a toothed rack (20) which is coupled with the spring arrangement (14). The axis of rotation (32) of the output shaft (30) extends through the centre of rotation (40) of the first toothed wheel (28). The entire device is arranged in such a way that the eccentricities of the toothed wheels (24, 28) resulting from their respective centre points (42, 44) and centres of rotation (38, 40) are point-symmetrical to their pitch point (46).

    • An automatic door closer and a process for mounting the same are disclosed. The dampening piston (2) has a coupling part (15, 39) and an outer part (30, 33). The coupling part is pre-mounted on the axle group (1) outside the door closer housing (20) and is then inserted into the housing. The outer part (30, 33) has no bores for connecting the piston to the axle group, which are usually located in the area of the sealing surfaces. The outer part (30, 33) is connected to the coupling part (15, 39) by a connecting member (3) that is screwed from the outside through the pressure chamber (32). This type of design significantly reduces the size of the door closer housing and in addition shortens mounting time.
