Definitions
- the invention relates to a switched single-stage or multi-stage suction jet pump comprising a motive nozzle, one or more suction nozzles, a diffuser and a flow control valve.
- the suction power of a conventional suction jet pump is regulated by the pressure applied to the jet nozzle.
- this driving pressure is diverted from the boost pressure of the engine and depends on the respective engine load point. The higher the torque generated, the greater the boost pressure.
- a suction jet pump is used to generate negative pressure in the crankcase or for tank ventilation, sufficient suction power is required even at low boost pressures.
- the suction power of the suction jet pump usually does not have to increase in parallel to the increasing boost pressure. For this reason, it makes sense that the suction jet pump is throttled from a certain boost pressure. This is to prevent the engine from unnecessarily diverting much air for combustion and reducing the power.
- EP 3 020 935 A2 relates to a vehicle having an internal combustion engine having a crankcase and a supercharger, with a crankcase ventilation device comprising an inertia-based oil separator having at least one inertia-based one Oil separator, a separated oil to the crankcase recirculating oil return and a suction jet pump which is driven with compressed air of the supercharger and which generates a negative pressure to drive blow-by gas. It is essential here that the suction jet pump is controlled and / or controlled by a control device. Here, the pump is throttled or switched off in the low boost pressure range. In the area of high pressure it is switched on maximally.
- the disadvantage of the known solutions is that at the first nozzle of the ejector not the maximum available Pressure is applied because the throttling takes place in front of the nozzle. Part of the energy used is always consumed at the throttle valve and can be considered as pure energy loss. Furthermore, the known systems build up very large.
- the object of the invention now consists in the integration of the throttle function directly into the motive nozzle of the ejector.
- the present invention consists of a single-stage or multi-stage suction jet pump comprising a motive nozzle 5, one or more suction nozzles in the intake 2 and a diffuser 7, which is characterized in that the suction jet pump in or immediately in front of the motive nozzle 5, a device for Reduction of the nozzle cross section and thus has to limit the drive current.
- Fig. 1 shows the invention with a self-springing valve body in unthrottled switching position.
- Fig. 2 shows the invention with a self-resilient valve body in a throttled switching position.
- Fig. 3 shows a possible curve of the driving and suction flow in response to the applied driving pressure.
- the invention consists of a single-stage or multi-stage suction jet pump as shown in FIGS. 1 and 2 with a motive nozzle 5, a diffuser 7 and optionally further nozzles 6.
- the overpressure area (1) which, for example, the boost pressure of a Turbomotors can be. Due to the overpressure, the driving fluid is accelerated by the driving nozzle 5, so that after the nozzle, the maximum speed is present. This increases the dynamic pressure in this area. For reasons of energy conservation, the static pressure drops. As a result, air is sucked in from the suction region 2 and then flows with the blowing air through the diffuser 7, where the flow is decelerated. This can be used, for example, to generate a vacuum in a crankcase or in a tank. The total flow 3 can then be fed back to the intake air of the internal combustion engine (for example, before the compressor).
- the device for limiting the blowing current (volume flow limiting valve) in the overpressure region of the suction jet pump has a valve body 4, which in particular comprises an opening 8 whose cross-sectional area is smaller than the cross-sectional area of the motive nozzle 5.
- the drive current limiting according to the invention is preferably achieved by a (sprung) valve body 4, which is mounted directly in front of the drive nozzle 5 of the suction jet pump.
- the suspension is preferably realized in the valve body 4 by spring arms.
- the valve body 4 is for example on a support surface 11 in the body of the motive nozzle 5.
- a compression or tension spring can be used.
- the spring element can be further biased. This can be realized for example by a hold-down 10.
- Fig. 1 it is shown that in the original state, the valve body 4 has a distance from the motive nozzle 5, so that a gap 9 between the valve body 4 and the body of the motive nozzle 5 is formed.
- the driving fluid flows through the valve body 4 in this state via the gap 9. Furthermore, the fluid may optionally flow through the opening in the valve body 4.
- the driving current increases (FIG. 2).
- the drive current and the Venturi effect lead to the formation of the total current 3.
- a mass flow control with a defined valve map is made available in a small space.
- the valve body 4 in particular a spring plate of the flow-through cross-section of the gap 9 between the Reduced pressure range 1 and the negative pressure range and thus regulated the motive mass flow.
- Another advantage of the present invention is that only one movable component, namely the valve body 4, in particular a spring plate is present.
- the valve body 4 serves to regulate the flow-through cross-section, preferably in the form of a spring plate.
- the spring plate can be installed, for example in the region of the overpressure 1 under a defined bias to release the path of the gas flow through the gap 9. If the pressure gradient increases due to a stronger propulsion jet pressure, then the valve body 4 moves toward the wall of the motive nozzle 5 up to the point that the gap 9 is completely closed.
- the valve body 4 generates a pressure loss depending on the drive current. If this pressure loss exceeds the spring force of the valve body, then it moves in the direction of the motive nozzle 5 and slowly closes the gap 9. As the motive pressure increases, the motive current decreases. The same applies to the suction flow in the intake 2. At the end of the closing of the valve body 4 seals on the body of the motive nozzle 5 approximately, so that the driving fluid can flow only through the opening of the motive nozzle 5 in the ejector, as in Fig. 2nd represented. Due to the smaller opening in the valve body 4, the drive current is limited. However, due to the increase in density of the fluid at higher driving pressures, there is a further, but shallow, increase in the driving current. The suction flow also continues to increase.
- the valve body 4 is preferably to be designed so that the pressure loss is low, so that as far as possible the complete driving pressure can be used to drive the suction jet pump.
- a further embodiment of the present invention is the use of the above-defined device for crankcase ventilation of an internal combustion engine in a housing between a crankcase of a crankcase and an intake tract or the tank ventilation.
