The invention relates to a rotor paddle (11) for a water motor (1), comprising a rotor paddle body (12) and a sealing device (22) for sealing an edge (19, 20) of the rotor paddle body (12) with respect to an inner wall (13) of a drainage housing (2) of the water motor (1), and to a water motor (1) having such a rotor paddle (11). The sealing device (22) has a sealing strip (23), which comes into contact with the inner wall (13) of the drainage housing (2), an elastic element (24), which is pretensioned in such a way that the restoring force of the pretension presses the sealing strip (23) in the direction away from the rotor paddle body (12), and a limiting unit (25), which limits the movement of the sealing strip (23) resulting from the restoring force of the pretension and/or the centrifugal force. Thus, the sealing strip (23) can be made of an inelastic but harder and lower-friction material, whereby the wear of the sealing strip is reduced. By virtue of the limiting unit (25), the sealing strip (23) is also prevented from partly detaching from the rotor paddle body (12) when the sealing strip passes over openings (3) in the inner wall (13) of the drainage housing (2) at the inlet (4) and outlet (5) of the water motor (1) and is temporarily not in contact with the inner wall (13) of the drainage housing (2).

A closing element for a valve, comprising
an upstream closing element side;
a downstream closing element side; and
a valve seat surface, wherein both closing element sides have a favorable shape in terms of flow and the valve seat surface is formed between the upstream closing element side and the downstream closing element side.
An adding system for fire-extinguishing units includes a motor, which can be driven by an extinguishing agent stream, an adding pump, which can be driven by the motor, an adding line, and an extinguishing agent additive line. The outer wall of the working chamber of the motor is in the form of a rotation motor, which can also have the shape of a logarithmic spiral. Furthermore, the wall of the drainage housing of the motor, which is in the form of a rotation motor, can have a through-slot for letting the extinguishing agent in and/or out. Moreover, the inlet of the adding pump can be arranged such that the extinguishing agent additive can flow into the adding pump substantially parallel to the movement direction of the pistons of the adding pump. Finally, the adding pump can have an integrated relief valve.

The invention relates to an admixing system for fire-extinguishing units, for producing a mixture of a fire extinguishant and a fire extinguishant additive (premix) by admixing a fire extinguishant additive, in particular a foaming agent, into a fire extinguishant, in particular water, said admixing system comprising a motor that can be driven by a fire extinguishant flow, and a mixing pump used to deliver the fire extinguishant additive, which is coupled to the motor and driven thereby. The admixing system comprises remote control means for transmitting and executing a command for the automatic start-up or shut-down of the motor and the mixing pump, as well as remote read-out means for automatically detecting and transmitting data relating to the state of the admixing system. The presence of an operator is therefore not required with the admixing system. These remote maintenance functions allow the operability of the admixing system to be verified without an operator having to physically go to the fire extinguishing unit with the admixing system, thereby significantly reducing the complexity and related maintenance costs.

An admixing system for fire-extinguishing installations is provided for generating a mixture (premix) of extinguishing medium and extinguishing medium additive by admixing an extinguishing medium additive to an extinguishing medium. The admixing system has a motor that can be driven by a flow of extinguishing medium, an admixing pump that is connected to the motor and serves for supplying the extinguishing medium additive to an extinguishing medium additive inlet line, an admixing line, and an extinguishing medium additive outlet line from which the extinguishing medium additive is admixed to the extinguishing medium in the admixing line. The admixing pump is a piston pump having multiple cylinders and at least two outputs connected to the cylinders. At least one first output, through which return flow is possible, can be switchably fluidically connected either to a return flow line through which the extinguishing medium additive flows back to the admixing pump, or to the extinguishing medium additive outlet line. If the extinguishing medium additive flows from the return-flow-compatible output back to the admixing pump, it is therefore not admixed to the extinguishing medium in the admixing line. Thus, the admixing rate can be changed simply by means of this switching.

The admixing system has a motor that can be driven by a flow of extinguishing agent, an admixing pump connected to the motor for pumping the extinguishing agent additive, an admixing line, and an extinguishing agent additive line, from which the extinguishing agent additive is mixed with the extinguishing agent in the admixing line. The admixing system has a branching line, from which a part of the flow of extinguishing agent can be branched off if the load in the fire extinguishing system only requires a small flow of extinguishing agent. In this manner, the flow of extinguishing agent flowing through the motor is artificially increased so that the motor runs in a higher rotational speed range in which a reliable operation of the motor is ensured (a so-called start-up flow reduction). The admixing system has a motor rotational speed measuring device and a controller, said controller being designed to completely or partly open and/or close the branching valve on the basis of the motor rotational speed measured by the motor rotational speed measuring device.

ADMIXING SYSTEM FOR FIRE-EXTINGUISHING INSTALLATIONS AND METHOD FOR OPERATING SUCH AN ADMIXING SYSTEM
The invention relates to an admixing system (1) for fire-extinguishing installations for generating a mixture (premix) of extinguishing medium and extinguishing medium additive by admixing an extinguishing medium additive, in particular a foaming medium, to an extinguishing medium, in particular water. The admixing system (1) has a motor that can be driven by a flow of extinguishing medium, an admixing pump (6) that is connected to the motor and serves for supplying the extinguishing medium additive to an extinguishing medium additive inlet line (35), an admixing line (10), and an extinguishing medium additive outlet line (13) from which the extinguishing medium additive is admixed to the extinguishing medium in the admixing line (10). According to the invention, the admixing pump (6) is a piston pump having multiple cylinders and at least two outputs (8a, 8b) connected to the cylinders. At least one first output (8b), through which return flow is possible, can be switchably fluidically connected either to a return flow line (29) through which the extinguishing medium additive flows back to the admixing pump (6), or to the extinguishing medium additive outlet line (13). If the extinguishing medium additive flows from the return-flow-compatible output (8a, 8b) back to the admixing pump (6), it is therefore not admixed to the extinguishing medium in the admixing line (10). Thus, the admixing rate can be changed simply by means of this switching.
