The invention relates to a device for controlling the opening width of a window or the like, with a fluid operated jar for Opening or closing the window and a switching device, which depending on a changeable Environmental condition the energy for actuating the impact device in the sense of opening or by closing the window.

A device is already known for automatically regulating the window opening in a greenhouse as a function of the temperature in the greenhouse, in which an electric motor drives a drive shaft which opens and closes each window via a rack and pinion gear. This known device has the disadvantage that a rack and pinion gear is required for each window and that the motor has the tendency to continue rotating due to the inertia after the electrical circuit has been interrupted. This causes could lead to large eruption of the window _s welehes in the closing direction causes the window closes too quickly, so that it becomes damaged.

In a still known hydraulic transmission device for actuating ventilation devices a window is operated by a pusher operated by a gear pump is controlled, which can be operated by hand by means of a lever. The operator consequently controls both the speed and the duration of the opening or closing movement of the Window by actuating and moving the lever accordingly. There is a risk of that improper handling of the lever results in too rapid a movement with excessive off " blow of the window is caused, which can lead to damage of the same.

It is also still known to open flaps by means of a fluid operated pusher device in FIG to move in an opening or closing direction, where 4 <J b6i a thermostat is provided which controls the supply of energy to the pushing device for actuation the flaps controls. In this known arrangement, the movement of the pusher and of the flaps or windows connected to it as a direct function of the temperature fluctuations via the thermostat. In the event of strong temperature changes, there are therefore strong deflections the flaps or windows, which can also damage them.

The object on which the invention is based is to provide a device of the device mentioned at the beginning for controlling the opening worlds
a window or the like.

Piston, which is connected to the thermostat 24 by a 5 The two outer terminals of the scarf tube 26, which a small bore ters 37 are on the connection blocks 43 and 44, has. The thermal sensor is in the greenhouse which is also shown in FIG. 1 are shown, attached to a point at which the temperature is to be regulated electromagnets 45, 46 of the valves 7 and 8, respectively. When the temperature closed in that. The hole in the block 9 is shown in FIG. 2 greenhouse is higher than the one on which the thermostat io is shown schematically as pipe 47. If the valve is set by a control button 27, tilts til 7 open, the beta entering at 10 will flow the mercury tube in such a way that a fluid flow to the ports 11 or pulse or a series of pulses passed through the 18, the to the impact device or the impact device pulse generator 22 are generated, the electrons 1 lead. The fluid is energized by the magnet of the valve 7, whereby the window 15 pusher or pusher devices 1 above or the windows of the greenhouse are opened, so the connections 11 and 18 to the outlet 12 above that the temperature drops. Drain the mercury tube into valve 8 when it is open. The valves 19 and 20, which are manually operated for the thermostat, would then assume their reference position, in which no impulses are applied to each of the elec- tromagnets of the valves 7 and 8 which are operated by the shock devices 1. If 20 is to be opened or closed, and the temperature in the vicinity of the thermocouple valves 7 and 8 parallel-connected shunt 25 falls below the temperature to which the thermocouples 14 and 15 and the manually operated valves stat is set the solenoid of the valve 8, 16 and 17, which excites the flow through the secondary, whereby the window or the window closing lines 14 and 15 respectively, are closed in FIG. 2 and the greenhouse becomes warmer. 25 shown.

The operation of the device is as follows: the generator device 22 comprises a disk 29; 1 is shown, and the disk 29 is constantly rotating during operation and at the common of the device constantly with constant flow rate by a synchronous electric motor 30, whose duration and frequency are as described above via a reduction gear 31 and a bevel gear - is set. The switch 37 acts as a three-way gear 32 is rotated. The electric motor 30 is switch depending on the difference between the temperature via a main switch 33 and the terminals 23 to which the temperature sensor responds, and which is connected to the network, which is also shown in FIG. 1 ge reference temperature to which the thermostat 24 are shown. The disk 29 carries four or one other 35 positions, and will conduct either a pulse or Im-number of equally spaced pulses to the electromagnet 45 or 46 or pins 34 which do not conduct any pulse parallel to the axis of rotation of the disk. Extend the duration of each pulse. As the disc 29 is rotated, the length of movement of the pusher determines the pins 34 to move in a circular path and direction during each effective pulse, and therefore sequentially engage with one actuation, the speed of window movement. The release lever 35 of a microswitch 36, which is variable between the frequency of the pulses, so that the Temeine of the input lines to the motor 30 and the rate of change of temperature can be adjusted; the faster the temperature fluctuations, the faster the temperature fluctuations are, the more quickly the thermostat 24 is connected to the common terminal of the mercury scarf. The frequency of the impulses should be greater,
When a pin is in engagement with the lever 35, the microswitch 36 is switched on by opening one or more valves 20; this NEN the electromagnetically operated valves to switch off again as soon as the pin is used by which several pushing devices 1 equal operating lever comes free. Actuate early when turning. For example, a shock disk 29 can be a series of voltage devices regulate the windows on one side of an impulse on the common terminal of the 5 ° greenhouse roof and another, electromagnetically operated valve operated by the mercury switch in the thermostat 24 powered testifies. In Fig. 2 is the latter switch with 37 pushing device which draws the windows on the other side. The duration of the impulses is regulated by regulating a greenhouse roof. Moving the two pushing front lever 35 up and down directions would tend to look like themselves in FIG. 2, whereby the time changes, would be the same and would therefore be based on a difference in the one pin 34 in engagement with the lever of the wind force that stands on the window at the corresponding 35. The microswitch 36 acts including the corresponding sides of the roof, respond. At lever 35 is mounted on a plate 137 which, in another arrangement, can move a pulse generator as a whole up and down, seen 22 supply several blocks 9, each of which is elec Valves 1, 8 wear and each one in F i g. The control knob 40 shown in FIG. 1 is rotated because its own thermostat 24 including the spindle 39 is rotated. The button 40 is associated with a three-way switch 37,
provided with a pointer which moves over a scale 41 the manually operated bypass valves 16, 17, which can be divided into units, for example seconds, it is possible for the associated pusher device to be subdivided. The frequency of the pulses 65 or pushers 1, manually rather than automatically, is changed by removing pins 34 or actuating the table. To be replaced in place of the shunt. If all four pins are in their control valves 16, 17, manually operated switches can be pre-regulated, for example an impulse occurs to all be able to see the middle connection of the three-way

switch ^ 37 au deü one or the other outer Connection of the same, where the electromagnets 7 or 8 are energized, regardless of the position of the three-way holding device so that the pusher Is operated in a desired direction.

Instead of the rotating pin disk 29, any other electrical pulse generator can be used. to be used. For example, this can comprise transistors and therefore of a more compact design and only require a small amount of energy.

In the case of the in FIG. 3 shown second embodiment of the device, the pulse-generating device is fluid-operated and not electrically Irish type, the pulse generating means being a pulse of pressurized fluid via a valve to the shock valve supply.

An adjustable drip feed device has already been proposed which is set up in such a way that it feeds water or another fluid to a siphon container 51 which, when a predetermined amount of water has accumulated therein, empties irl an articulated equalizing reservoir 52 ″, which in turn empties emptied to actuate a servo valve 53 m which is arranged to actuate a valve 54 which regulates the water as inflow through an inflow pipe and thus generated water pulses of the inflow pressure at an outlet connection 50 the frequency of the pulses, and the rate of flow from the surge tank 52, controls the volume of each pulse.

The connection 55 is provided with a tube 56 which leads to a chamber 57 in a block 58 which comprises a piston 59 forming a passage valve. The plunger 59 is moved by a plunger 60 of a temperature sensitive device as shown, which is responsive to the temperature in the greenhouse or in another room. The piston 59 has three positions, namely a "window-opening" position in which a water pulse is passed through the tube 56 to the shock device 1, a "window-closing" position in which a pulse is directed to a piston 61 instead , which regulates a tap valve 62, which leads from the pusher 1 to a waste water outlet 63, and SB a neutral position in which no pulse is sent to the pusher 1 or the piston 61 WM ₁ Instead of the pulses directly to the pusher 1 or the To direct the bleed valve 62, they can also be directed so that they actuate a servo piston which actuates the thrust valve 1

As with the first embodiment, the pulse generating device actuate more than one jar 1, each of which is its own Has Durehläßventil. In another request Any impulse-generating facility and each associated gate valve collectively regulate more than one pusher.

The pusher device 1 shown as an example in FIG. 3 is shown as an eiflfäeh acting pusher device, the operating stroke opening of a window OS, while the latter is closed by the action of a counterweight 66. For example, the window will still appear 65 or more windows operated by a shaft 67, which is rotated by the movement of a pusher.
