    摘要: Suction jet pumps are already known with a driving line (1) which leads via a jet outlet into a suction chamber (3), wherein the suction chamber has a suction opening (5) which interacts with a valve element (6) and through which fluid can be sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank (11) and sucks fuel out of a fuel tank into the storage tank. At low levels in the fuel tank, air may sometimes be sucked up and conducted into the storage tank, as a result of which foaming occurs in the storage tank. However, the large volume of the foam causes fuel to be displaced, which may result in partial emptying of the storage tank. This effect is also referred to as dynamic leakage. A characteristic curve of the suction jet pump that represents the suction power as a function of the driving stream has a comparatively steep gradient. Severe foaming occurs only above a critical suction power of the suction jet pump, referred to below as the foam limit. In the case of the suction jet pump according to the invention, foaming is avoided or at least reduced. According to the invention, it is provided that the driving line has a bypass opening (10) which leads into the suction chamber and is arranged in such a manner that the bypass stream thereof acts on the valve element.

    摘要: The invention relates to a ventilation device for ventilating shower streams that is configured as an insert, and that may be utilized in a connection of a sanitary fitting, particularly in the connection of a shower head housing. The insert contains at least one water throughput channel (15) connected to a ventilation channel (18, 19, 20, 21) such that air is suctioned in through the ventilation channel (18, 19, 20, 21) when a flow passes through the water throughput channel (15), ventilating the water stream. The insert may have a receptacle for a flow restrictor (11). A backflow preventer (13) may be provided in order to prevent water leakage from the exterior end of the ventilation channel.

    摘要: Accordingly, it can be seen that our Double Funnel Float Valve 10 functions both as a valve and as a trap in liquid supply and liquid disposal systems. It functions without a power source and without mechanical parts, making it inexpensive and durable. It is designed to be easily installed to standard plumbing, virtually maintenance free, and the only movable parts, the floating ball 14, weighted oval shuttle 16, and aspiratory shuttle 24, can be easily replaced.
    Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Various other embodiments and ramifications are possible within it's scope. For example, the double funnel float valve 10 might also be configured as a faucet or, on a larger scale, sewer systems.
    Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.

    摘要: Vacuum generating means for providing reduced pressure for sewage transport in a vacuum sewer system, which means comprises a liquid-driven ejector (3), the working medium of which is fed to the ejector (3) by a circulation pump (6) from a sewage collecting container (5), the suction side (4) of the ejector 3 being, via a check valve (9), connected to a vacuum sewer network (2) . Sewage delivered through the sewer network flows through the ejector (3) into the collecting container (5). The bore of the discharge pipe (11) of the ejector, is substantially cylindrical throughout. Its length (L) is 8 to 20, preferably 10 to 15, times the diameter (D) of its bore and the pipe (11) discharges directly into the open interior of the collecting container (5).
