PATENT OFFICE.

The invention relates to a steam trap, in which the of a moving organ, for example the movement caused by a swimmer is not transmitted directly to a valve, but by means of a switching device, which is released by the float in one sense or the other and in turn moves the valve, opening it as well as closing is effected quickly.

The switching device of the previously known steam water trap of this type is almost always moved by counterweights that only allow regulation when one is over has a sufficiently large room; furthermore, the counterweights worked on all devices of this kind with the maximum of their power at both ends of the path so that the required work of the Float must also be a maximum in order to cause a notch, which causes difficulties in the effect and can cause great inconvenience, all the more so because of the whole mechanism works in water and thus the joints are subject to oxidation, which impairs good work.

The present invention aims to avoid these shortcomings.

The invention consists essentially in the use of a switching device which is composed of springs with two rod systems articulated together. the Bars of every system form a certain angle with each other. The first of these Systems is under the influence of the swimmer, the second is under the influence of the the former system and moves the valve of the device when the former is released Rod system, the springs for usually none or at least only a very large number of springs exert little force when the float is at its stroke ends, d. H. so with the valve closed or open, while the springs are probably at the moment the disengagement of both rod systems are able to act with the maximum of their tension.

Such a steam water separator is shown in the drawing.

Fig. Ι is a vertical section through the lower part of the steam water separator;

Fig. 2 is a plan view of part of the switching device.

In the illustrated embodiment, the water from the pipe 1 passes through the Opening 2 in the container where it will collect on the bottom, taking care is that the water flows into the container at such deep points that_ thereby the rising or falling of the float 3 cannot be directly impaired. The float is supported by a vertical Rod 4 guided between two stops 5 and 6. The parts 7, 8, 9, IO and 11 are located on the container

and io springs 12 are attached, which allow joints 13 and 14 to move horizontally but not vertically. The valve rod 15 moves the conical double valve 16 and is in the parts 7 and 11 out. As already said, the upper end of rod 4 is for example out in the lid of the device. The lower end of the rod 4 carries at a joint 18 the rods 19 and 20, one of which is 19 at 13 at the end of the Spring 12 and the other 20 are hinged at 21 to the fixed part 8. on the other hand the joint 18 is connected to a joint rod 22, which at 23 with which the valve moving rod 17 is articulated together. This joint 23 is in turn mediated one or two rods 24 connected to the joint 14, which is connected to that of the fixed Part 9 held spring engages. When the levers are in the position shown in full lines in Fig. I, so the two rods 19 and 20 form, so to speak, two sides of a rhombus, the with the rod 20 is articulated at 21 on the fixed part 8, while he is with that of the action the spring 12 underlying rod 19 is connected at 13 such that a horizontal Shifting this pivot point is possible. The drawn position of the rod 4 indicates their lowest position. The rods 22 and 24 also form two sides of a rhombus, one of which Fulcrum 14 is subject to the action of the spring 12 carried by the fixed part 9, while the other pivot point with the pivot point just described 18 of the Rods 19 and 20 formed rhombus coincides. In the full lines position of the rods shown, the double valve 16 is closed and is also through the horizontal pressures generated as a result of the action of the springs 12 on the one hand of the Joint 14 in the direction of the joint 13 and on the other hand the joint 13 in the direction on the joint 14, whereby the joint connected to the valve rod 17 is pushed up is kept closed. The up and down movement of the joint 18 is of course limited by suitable means Stops of the rod 4 in the housing cover. If the swimmer becomes 3 as a result the buoyancy of the water entering the container against the stop 5 of the Pushed rod 4, the latter and thus the joint 18 is pushed upwards, thereby but the valve rod 17 also receives an upward movement, so that the valves 16 stay tightly closed. When the joint 18 crosses the straight connecting line between the joints 13 and 21 has come out, the pressure seeks through the springs 12 relaxing in the process the joint 13 to bring about a further upward climb of the joint 18, so that the Valve remains closed all the time. But as soon as the joint 18 a little the extension the rod 24 has exceeded, is under the pressure of the springs 12 of Articulation point 23 suddenly assume the position shown in FIG. 1 in dotted lines is reproduced, while at the same time the levers 19 and 20 are also dotted Will take positions so that the levers are in a sense the mirror image of the previous one Position the lever and thus form the other two sides of the rhombus. That The valve is opened and remains open until the float 3 descends hits against the stop 6, whereby all levers and rods are brought back to their previous position and that too Valve 16 is closed again. The downward movement of the valve is controlled by a stop 25 on the rod 17 limited, which strikes against the fixed thrust bearing 7. The swimmer, when he starts, needs rod 4 in one or the other Take your senses with you, only exert a very small amount of force, and the springs 12 can be set so that they exert almost no force in this position of the lever ; however, the moment the notch takes place, the effect is of the springs, which are then fully under tension, maximum; the joints consequently make the slightest deflection, although moving from the maximum of the force will. The device described allows the swimmer any altitude to give, while in the previously known arrangements the altitude of the swimmer or swimmers always by the necessary maximum deflection for movement of the device was limited.
