Definitions
- the invention relates to a device for switching cyclones.
- Cyclones are used, for example, in the crankcase ventilation of internal combustion engines. They are used to separate the crankcase gas from liquid components such as oil mist.
- the crankcase gas is set in rotation in the cyclone.
- the oil mist or the oil droplets are deposited on the wall of the cyclone and from there flow back into an oil pan via a discharge pipe.
- the de-oiled gas reaches the intake tract of the internal combustion engine via a pressure control valve and is fed back to the intake air.
- crankcase gas depends on the operating state of the engine and can range from 50 to 220 l / min.
- a cyclone has an optimal operating point for a certain amount of gas. In order to reliably de-oil the different amount of gas, it is necessary to provide several switchable cyclones, which are switched on or off depending on the amount of gas. Approaches are known for this, such as. B. the use of additional valves that switch the cyclones on or off.
- DE 199 18 311 discloses a method for deoiling crankcase ventilation gases and a device for carrying out the method.
- 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 separating element, the size of the partial volume flows being regulated depending on the size of the volume flow.
- the invention is therefore based on the object of providing a device which makes it possible to accomplish a reliable switching on and off of cyclones without great expenditure on components. This object is achieved by the features of independent claim 1.
- the main advantage of the invention is that a control piston is provided.
- This control piston is designed such that, depending on the dynamic pressure of the crankcase gas, it opens or closes the access of the gas to a first or a further cyclone.
- a compression spring is provided to reset the control piston or as a force component against the back pressure of the crankcase gas. This enables an efficient control of the volume flow and a distribution over several partial volume flows.
- the entry into the at least two cyclones is cylindrical, and there is a holding pin for receiving the compression spring and receiving the control piston.
- three cyclones are advantageously provided, the control piston having a passage opening in the bottom and being connected to the first cyclone. This means that with a very low volume flow, the first cyclone is effective and a liquid separation takes place, if a higher volume flow has to 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. If the volume flow increases, a third opening to the third cyclone is also opened, so that at a maximum volume flow three cyclones are acted upon and are available for cleaning the crankcase gas. To seal the control piston and its outer surface, this can have suitable sealing rings.
- the cyclones are arranged in a common housing in an advantageous manner, this housing has a floor drain which, according to a further development, is provided with a valve and is suitable for the collected liquid to circulate, i.e. in the oil circuit of the internal combustion engine.
- the volume flow can also be controlled via a diaphragm valve.
- This diaphragm valve is characterized by the pressure difference between the pressure of the crankcase gas before the cyclone, i.e. controlled the pressure of the uncleaned crankcase gases and the pressure of the crankcase gases after the cyclone.
- the pressure difference leads to the closing or opening of additional cyclones. At a maximum pressure difference, all cyclones are open.
- the membrane 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 access to two cyclones.
- the diaphragm valve can also be equipped with a piston which moves along a cylinder wall. Openings are provided on this cylinder wall, which are connected to the cyclones. By moving the piston, these openings are closed or released. This very simple construction is also suitable for regulating the distribution of the crankcase gases and thus achieving an optimal cleaning effect.
- Figure 1 is a schematic representation of a device for deoiling
- FIG. 2 shows a schematic top view of the illustration shown in FIG. 1,
- FIG. 3 shows a variant of a device with a diaphragm valve
- Figure 4 shows another variant with a membrane plate
- Figure 5 is a 3D representation of a valve for controlling the activation of cyclones.
- 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 floor drain 15 which is closed with a drain valve 16.
- the drain valve 16 opens the opening 17 if a certain fluid pressure is on the valve.
- the housing 14 is closed with a cover 18.
- the cleaned crankcase gases can be fed to the intake tract of an internal combustion engine.
- the gases to be cleaned flow in via the opening 23.
- FIG. 2 This opening is shown in more detail in FIG. 2.
- the same parts are provided with the same reference numerals.
- the cyclones 11, 12, 13 are shown in plan view.
- a feed line 24, 25, 26 leads to each cyclone.
- the feed lines open into a common opening 23 is cylindrical, there is a control piston 27.
- This control piston is attached to a holding pin 28 and guided at the same time.
- a compression spring 29 is pushed over the retaining pin and 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. The opening for the crankcase gases to be cleaned is thus connected to the feed line 26 for the cyclone 13.
- FIG. 3 shows a construction of a device for deoiling 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 membrane valve 41 is provided to regulate 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 a plate 45 in the central area.
- Two plungers 46, 47 are arranged on this plate. The plunger 46 can close the feed line 39, the plunger 47 can close the feed line 38. In the illustration shown here, the feed line 38 is open and the feed line 39 is closed.
- a compression spring 48 and a spring guide 49 are provided on the side of the rubber membrane 42 opposite the plate.
- the compression spring provides a force component on the rubber membrane 42 in the direction of the guide lines 38, 39.
- the opening 50 connects the space inside the cover 44 to the connecting line for the gases cleaned by the cyclones, so that the pressure of the connecting line continues into the space inside the cover 44.
- the pressure of the crankcase gases to be cleaned prevails due to the opening 51. This means that the feed lines 38, 39 are closed by the plungers 46, 47 at a low pressure on the raw gas side. If the pressure on the raw gas side increases, the membrane is loaded against the force of the compression spring 48 and moves in the direction of the compression spring, so that the supply line 38 is released first, and later the supply line 39 is released.
- FIG. 4 schematically shows a simple solution for regulating the gas distribution to the cyclones 52, 53, 54. These are located next to a feed line 55.
- a slide 56 which is attached to a membrane 57.
- the slide 56 has a passage opening 58. While the cyclone 52 is open in every operating state, the opening 58 moves depending on the action on the membrane and releases the cyclone 53, 54.
- FIG. 5 shows in a 3D representation a housing for a control piston, as is shown in a similar structure in FIG. 2.
- 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 takes place via a compression spring 63.
- This compression spring is fastened to the control piston 60 via clamps 64, 65, 66.
- the control piston is acted upon by the flow pressure of the crankcase gas in direction A on the end plate 71. Depending on the volume flow, this causes a movement against the pressure of the spring 63. Because of an existing annular gap between the end plate 71 and the housing wall 61, the crankcase gas can flow past this end plate and reaches a first cyclone.
- the control piston 60 is slidably arranged on a carrier 72.
- This carrier 72 has guide surfaces 67, 67a.
- the carrier 72 is clutched by the control piston 60 in the region of these guide surfaces and on the boundary walls arranged in this region. On this so-called dovetail guide, 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 shown here.
- a window 70 on the control piston 60 opens these openings 68, 69 or closes the openings if only a low crankcase gas pressure is present.
- crankcase gas pressure is at a maximum, that is to say both these two cyclones are open and also a cyclone which is in a continuously open state. If the crankcase gas pressure decreases, the opening 69 is first closed by the control piston and then the opening 68.
- the structure shows a simple and effective valve for regulating the crankcase gas flow and distributing it to the plurality of cyclones. Of course, there is also the possibility of controlling a plurality of cyclones by appropriate configurations of the window 70 or further openings below this window.
