Definitions

  • the invention relates to a device for switching cyclones.
  • Cyclones are used for example in the crankcase ventilation of internal combustion engines. They serve to separate the crankcase gas from liquid components such as oil mist. The crankcase gas is thereby set in rotation in the cyclone. The oil mist or oil droplets settle on the wall of the cyclone and flow from there via a discharge pipe into an oil sump. The de-oiled gas passes via a pressure regulating valve to the intake tract of the internal combustion engine and is supplied to the intake air again.
  • crankcase gas depends on the operating condition of the engine and may be in the range of 50 to 220 l / min.
  • a cyclone has an optimal operating point with a certain amount of gas. In order to reliably degrease the different amount of gas, it is necessary to provide a plurality of switchable cyclones, which are switched on or off depending on the amount of gas. For this purpose, approaches are known, such. B. the use of additional valves which turn on or off the cyclones.
  • the volume flow of the crankcase gases is divided into at least two partial volume flows, and at least one partial volume flow is passed through at least one oil separator element, the size of the partial volume flows being regulated as a function of the size of the volume flow.
  • the invention is therefore an object of the invention to provide a device that makes it possible to accomplish a reliable switching on and off of cyclones without much component effort. This object is solved by the features of independent claim 1.
  • the essential advantage of the invention is that a control piston is provided.
  • This control piston is designed such that it opens or closes the access of the gas to a first or another cyclone depending on the back pressure of the crankcase gas.
  • a compression spring is provided to reset the control piston or as a force component against the back pressure of the crankcase gas. This makes it possible to achieve an efficient regulation of the volume flow and a distribution to several partial volume flows.
  • the entry into the at least two cyclones is configured cylindrically, therein is a retaining pin for receiving the compression spring and the receptacle of the control piston.
  • further education three cyclones are provided, wherein the control piston in the bottom has a passage opening and is in communication with the first cyclone. This means that at very low flow rate, the first cyclone is effective and a liquid separation takes place, if a higher volume flow must be cleaned, the control piston deviates from the rest position against the force of the compression spring and opens another passage for the volume flow.
  • this may have suitable sealing rings.
  • the cyclones are arranged in a common housing in an advantageous manner, this housing has a bottom drain, the further education provided with a valve and is suitable that the liquid collected in the circuit, i. attributed to the oil circuit of the internal combustion engine.
  • a control of the volume flow can also be done via a diaphragm valve.
  • This diaphragm valve is characterized by the pressure difference between the pressure of the crankcase gas before the cyclone, i. the pressure of the uncleaned crankcase gases and the pressure of the crankcase gases after the cyclone controlled. The pressure difference results in closing or opening of additional cyclones. At a maximum pressure difference all cyclones are open.
  • the diaphragm valve consists of a rubber-elastic membrane, which is acted upon by a compression spring. Two plungers are provided on this membrane via a plate. These close or open the access to two cyclones.
  • the diaphragm valve may also be equipped with a piston which moves along a cylinder wall. On this cylinder wall openings are provided which are in communication with the cyclones. By moving the piston, these openings are closed or released. Also, this fairly simple structure is suitable to achieve a regulation of the distribution of the crankcase gases and thus an optimal cleaning effect.
  • the device 10 according to FIG. 1 consists of three cyclones 11, 12, 13, which are arranged in a common housing 14.
  • the housing has a bottom drain 15, which is closed by a drain valve 16.
  • the drain valve 16 releases the opening 17, provided that a certain fluid pressure on the valve loads.
  • the housing 14 is closed by a lid 18.
  • Above the cover 18 is a closing body 19, which receives the cleaned by the cyclones 11, 12, 13 crankcase ventilation gases. These gases are passed via the line 20 and via a pressure regulating valve 21, not shown here, to the outlet line 22.
  • the cleaned crankcase gases can be supplied to the intake tract of an internal combustion engine.
  • the gases to be purified flow in via the opening 23.
  • This opening is shown in more detail in FIG. Identical parts are provided with the same reference numerals.
  • the cyclones 11, 12, 13 are shown in plan view.
  • To each cyclone leads a supply line 24, 25, 26.
  • the supply lines open into a common opening 23.
  • this opening 23 which is cylindrical, there is a control piston 27.
  • This control piston is attached to a retaining pin 28 and guided simultaneously.
  • About the retaining pin a compression spring 29 is pushed, which exerts a force on the control piston in the direction of the opening 23.
  • the control piston has at least one opening 30 on the bottom facing the compression spring.
  • FIG. 3 shows a structure of a device for de-oiling crankcase ventilation gases with three cyclones 34, 35, 36.
  • Each cyclone has its own supply line 37, 38, 39.
  • the crankcase gases to be cleaned pass through the opening 40 to the supply lines.
  • a diaphragm valve 41 is provided to control the distribution of the volume flows to the cyclones.
  • This consists of a rubber membrane 42 which is clamped between the housing 43 and a cover 44.
  • the rubber membrane carries in the central region a plate 45.
  • On this plate two plungers 46, 47 are arranged.
  • the plunger 46 can close the supply line 39, the plunger 47, the supply line 38. In the illustration shown here, the supply line 38 is opened, the supply line 39 is closed.
  • a compression spring 48 and a spring guide 49 are provided on the side opposite the plate side of the rubber membrane 42.
  • the compression spring provides a force component on the rubber membrane 42 in the direction of the supply lines 38, 39.
  • the space within the cover 44 is connected to the connection line for the gases purified by the cyclones, so that the pressure of the connection line continues into the space inside the cover 44.
  • the pressure of the crankcase gases On the opposite side of the rubber membrane 42 prevails due to the opening 51, the pressure of the crankcase gases to be cleaned. This means that at a low raw gas pressure, the supply lines 38, 39 are closed by the plungers 46, 47. Increases the raw gas pressure, the membrane is loaded against the force of the compression spring 48 and move in the direction of the compression spring, so that first the feed line 38 and later the feed line 39 is released.
  • FIG. 4 schematically shows a simple solution of a regulation of the gas distribution to the cyclones 52, 53, 54. These lie next to a supply line 55.
  • a slide 56 In the supply line 55 there is a slide 56, which is fastened to a membrane 57. Again, the membrane is acted upon on the right side with the pressure of the clean gas and left side with the pressure of the gas to be cleaned.
  • the slide 56 has a passage opening 58. While the cyclone 52 is opened in each operating state, the opening 58 shifts depending on the loading of the membrane and releases the cyclone 53, 54.
  • FIG. 5 shows, in a 3D representation, a housing for a control piston, as shown in a similar construction in FIG.
  • This control piston 60 is located in a cylindrical housing 61 and can move there along the arrow 62.
  • the support at the end of the housing via a compression spring 63.
  • This compression spring is attached via brackets 64, 65, 66 on the control piston 60.
  • the control piston is acted upon by the flow pressure of the crankcase gas in the direction A on the end plate 71. Depending on the volume flow, this causes a movement against the pressure of the spring 63. Due to an existing annular gap between the end plate 71 and the housing 61, the crankcase gas can flow past this end plate and enters a first cyclone.
  • the control piston 60 is arranged displaceably on a carrier 72.
  • This carrier 72 has guide surfaces 67, 67a.
  • the carrier 72 is gripped by the control piston 60 in the region of these guide surfaces and on the boundary walls arranged in this region.
  • the control piston 60 can move along the carrier 72.
  • two openings 68, 69 are provided in the carrier 72 itself. These openings are connected to the other cyclones, which are not provided here, connected.
  • a window 70 on the control piston 60 releases these openings 68, 69 or closes the openings, if only a small cure belgepurtig is applied.
  • crankcase gas pressure is maximum, ie both these cyclones are open and a cyclone which is in a permanently open state. If the crankcase gas pressure is reduced, first the opening 69 is closed by the control piston and then the opening 68.
  • the structure shows a simple and effective valve for controlling the crankcase gas flow and distribution thereof to the plurality of cyclones. Of course, it is possible to control several cyclones by appropriate embodiments of the window 70 and other openings below this window.
