摘要： In a high-pressure cleaning apparatus with a high-pressure pump for a cleaning liquid connected on the suction side to a preliminary tank with a feed pipe for cleaning liquid and having in the pressure pipe a bypass pipe branching off from this pressure pipe and leading to the preliminary tank, and with an electromotor driving the high-pressure pump and having a coolant pipe through which cleaning liquid flows, in order to also ensure effective cooling of the electromotor in the recirculation mode without loss of coolant, it is proposed that the feed pipe to the preliminary tank have a greater conveying capacity than the coolant pipe and that the coolant pipe lead into the preliminary tank in which there is a means for limiting the filling level.

摘要： A safety vacuum cleaner including a measuring system for residual dust monitoring, including a housing having an air passage with an inlet, an outlet, and a flow cross section. A turbine is disposed within the air passage and is rotatable to move an air stream through the air passage, the air stream containing dust particles. The turbine is electrically grounded such that electrical charges associated with the particles are removed upon contact of the particles with the turbine. A filter element is disposed within the air passage, and at least one electrode is disposed within the air passage downstream of the turbine, the electrode shaped as a grid covering the flow cross section of the air passage. The electrode conducts an electrical current responsive to contact with uncharged particles and emits a measurement signal indicative of the amount of the particles in the air stream.

摘要： A binary atomizing nozzle includes a housing having a liquid insert and a gas insert. The liquid insert has an interior chamber and a liquid inlet and a liquid discharge communicate with the chamber. A spin insert is positioned in the chamber so that liquid flowing from the chamber is given a rotational spin and exits the liquid discharge as a hollow cone. The spin insert is threadedly engaged with the wall of the chamber so that the liquid discharge constantly wets the wall portion of the flaring discharge. The liquid insert has an outer portion spaced from the gas insert and provides an axially extending annular chamber having a gas discharge. The liquid discharge is axially spaced a preselected distance from the gas discharge so that gas exiting the gas discharge flows along the outer portion of the liquid insert according to the Coanda effect and thereby atomizes the liquid exiting the liquid discharge.

摘要： A cylindrical inset forming a mixing chamber in a binary atomizing nozzle is mounted in a housing ahead of the nozzle discharge and is provided with radial boreholes. The liquid to be atomized, for instance water, and the atomizing gas, for instance air, are fed to the cylindrical inset, with the liquid arriving axially and the gas passing radially from an annular spacing surrounding the inset within the nozzle housing through the radial boreholes into the inset. The radial boreholes are located in several consecutive transverse plans when viewed in the direction of flow and are arrayed in mutually offset manner in the circumferential direction of the cylindrical inset.

摘要： A dual-material atomizing nozzle comprises a housing (10) with a gas intake (13), a liquid intake (14) and with a mixing chamber (11) for the gaseous and liquid components; a rod-like insert (16) flaring into a saucer-shape opposite the nozzle exit extends through the mixing chamber (11) along its longitudinal axis (15); the end of the housing (10) which is at the nozzle exit side is thus covered while forming an approximately radial, annular-gap shaped nozzle exit slot (23).At least one convergent/divergent tube-path (28, 29; 25, 24) based on the Laval principle is provided within the mixing chamber (11) no farther than the nozzle exit (12). Thereby, and especially when a second convergent/divergent tube path (25, 24) is present behind the liquid intake (14), first the gas and also the mixture of gas and liquid will be accelerated within the nozzle housing (10) to supersonic speed. In this manner a dual-material atomizing nozzle is created with an adequately large angle of jet and providing fine droplets, being insensitive to soiling and requiring only a slight ratio of gas to liquid, being resistant to wear and clogging.
摘要翻译：双材料雾化喷嘴包括具有气体入口（13）的壳体（10），液体进口（14）和用于气体和液体组分的混合室（11）与喷嘴出口相对的碟状插入件（16）沿其纵向轴线（15）延伸穿过混合室（11）; 因此，在形成大致径向的环形间隙形状的喷嘴出口槽（23）的同时，在喷嘴出口侧的壳体（10）的端部被覆盖。至少一个基于拉瓦尔原理的收敛/扩散管路径（28,29; 25,24）设置在混合室（11）内，不比喷嘴出口（12）更远。因此，特别是当在液体进口（14）后面存在第二收敛/扩散管路径（25,24）时，首先将气体以及气体和液体的混合物在喷嘴壳体（10）内加速至超音速速度。以这种方式，产生双材料雾化喷嘴，其具有足够大的喷射角度并且提供细小的液滴，对污染不敏感，并且仅需要气体与液体的轻微比例，耐磨损和堵塞。
