Water supply control for driving and handling of water supply

The invention relates to a water jet actuator as described in the preamble of the main claim.

Water jet drives of this type, which are used with propeller or centrifugal pumps or the like and which operate on internal combustion or electric motors, are known and function either as transverse jet propellers, especially bow thruster rudders, or controlling.

The parts of these water jet drives, i.e. the pump, its housing, control device, ducts, motor, engine base and other conventional auxiliary devices, have hitherto been mounted individually on watercraft and possibly welded individually to the hull of the ship. This created disadvantages in terms of storage, installation and replacement of equipment of this quality.

For this reason, the invention is based on a water jet sprayer of the type described at the beginning, which is simpler to store, transport, install and dismantle.

The object underlying the invention is solved by a water jet operator having the features of claim 1.

The lightweight construction is clear from the features of claim 2, whereby the preferred construction of the transverse jet rudder, in particular the bow jet rudder, is clear from the features of claim 3. A suitable design for a drive device with mainly control will become apparent from the features of claim 4. In this case, it is customary to equip four channels in four main directions. However, for example, one channel may be left out of one of the main directions, for example when the water jet is pushed back freely or when pushing water forward is out of the question. For such control devices around them, all four or more channels for the engine chassis come into question. Thus, when the motor in the transverse jet origin is most often transverse to the longitudinal axis of the vessel, it can be preferably both transverse and longitudinal in the steering around it. A very advantageous arrangement is achieved in a control device according to the features of claim 5.

Other advantages and features of the invention will become apparent from the following description.

The invention is explained by means of Figures 1 and 2. They see:

Figure 1: invention used in a transverse jet rudder,

Figure 2: Invention used for a drive and control device.

The propeller pump 1 (Fig. 1) is mounted in the housing 2 with a vertical axis so as to pivot so as to draw water from the bottom of the vessel, as is already known per se (DT-PS 22 15 344, US-PS 3 903 833).

The channel is connected on both sides by channels 3, 4 which lead to the steering side and the left side of the vessel 5. The flow of water sucked by the propeller pump is guided by a cover 6 optionally to one of the channels.

For this purpose, the cover is mounted for pivoting about a horizontal axis 7 in the housing and can be operated for pivoting by a hydraulic motor or other suitable drive device. The propeller pump is driven via a bevel drive 9, e.g. a bevel gear or worm gear or the like, and a universal joint shaft 10 by a motor 11. The example is an internal combustion engine, but it can also be an electric motor running at a constant speed, for example. In this case, the transverse thrust of the water is controlled so that the cover is only partially turned.

One of the ducts, namely 4, is fixedly connected to the housing 2 and together with the supports 12 forms the base of the motor. In this way, the pump 1, the housing 2, said channel 4, the water flow control device (cover 6), its drive 8, the motor 11 and the torque transmission elements 10, 9 form a structural unit which can be stored, transported and installed as such. By connecting the channel 4 to the motor base, a light construction method is obtained.

Figure 2 shows the use of the invention for control around it. The propeller pump 21, which may also be a centrifugal pump, is arranged with a vertical axis of rotation in a knee 22 mounted for pivoting about the same axis in the housing 23. The knee is L-shaped so that the water sucked by its vertical part can be pushed in the horizontal part in selected directions. The turning movement is provided by a motor 24. For the rotation of the propeller pump, a motor 25 is provided, which transmits its torque via the universal joint shaft 26 and the bevel gear 27 to the propeller pump. The ejected water can be led in four directions, namely through openings 28 and 29, which either lead out or can be connected to ducts, through a second opening opposite the opening 29 and which is therefore not shown in the drawing. Finally, the water can be led through a channel 30 which, together with the supports 31, forms the base of the motor. All the described parts form a structural group that can be transported and installed as a unit.

The connecting elements for connecting the channels and openings to the watercraft, e.g. the extension of the channels and openings, can be of any quality and are therefore not shown here. Auxiliary devices such as switches, cooler, battery, switch and control cabinet, etc. are not shown here and in the present case also belong to the unit according to the invention.
