Definitions

  • Pressure-controlled inlet valves and pressure-controlled outlet valves which are designed as so-called tongue valves, are generally used on a piston compressor. Controlling the volume flow with these previously known valves is only possible with piston compressors with several cylinders and also only in rough steps by cylinder deactivation.
  • a valve arrangement of this type can be found, for example, in DE-A-23 57 578, which has tongue valves designed as check valves both on the inlet side and on the outlet side.
  • valves In addition to compressor construction, there are also other applications for valves that have to react very quickly to existing pressure differences in order to be able to make targeted use of an existing pressure drop.
  • the invention has for its object to provide a fast switching tongue valve which avoids the disadvantages described above.
  • the object is achieved by a valve for influencing a flowable medium, in particular a gas, with at least one flow channel, the
  • Mouth is designed as a valve seat and with at least one valve body, which is arranged at the free end of a resilient arm clamped at the end, and with at least one electro-magnet, which acts on an area of the resilient arm designed as an armature and which, when energized via a control device, the valve body in moves its closed position and / or its open position.
  • a valve designed in this way has the advantage over the conventional tongue valves that not the entire valve tongue and its bearing surface on the valve plate serves as a valve seat, but a separate valve body is arranged which interacts with the mouth of the flow channel designed as a valve seat.
  • the valve body with its resilient arm is designed as a check valve and is evidently closable by the pressure of the flowing medium and can be closed by the action of the spring force and the magnetic force.
  • the valve according to the invention operates with respect to its opening process like a normal check valve.
  • the closing speed but also the closing time can be influenced by the targeted activation of the magnetic force. It is thus possible to initiate the closing movement if there is still a residual flow in the flow channel with a small pressure difference.
  • valve body is designed with its resilient arm as a check valve and is evident from the action of the magnetic force against the spring force.
  • a check valve it is possible to open the valve by energizing the associated electromagnet when a pressure equilibrium is present on both sides of the valve body.
  • the further advantage of this arrangement is that the valve opening is specifically opened to the full cross section at the beginning of the flow, so that the friction and the associated heating of the flowing medium is reduced.
  • valve according to the invention also allows a configuration as a check valve, in which two electromagnets directed towards one another are provided, so that both the opening movement and the closing movement can be influenced when the electromagnets are suitably energized.
  • two electromagnets arranged at a distance from one another are provided, which can be energized alternately via the control device and the valve body can be moved from a central position to the fully open and the fully closed position by magnetic force against the action of the spring force.
  • this arrangement allows the valve to be opened and closed in a specifically controllable manner with very short switching times and high switching frequency, both the opening and the closing beginning being predeterminable in each case via the corresponding control of the energization.
  • the spring arm has practically only the meaning of a return spring which accelerates the release of the armature part from the pole face of the holding magnet after the current has been switched off.
  • the spring arm also serves as a support for the anchor.
  • the spring stiffness of the spring arm can be specified very low, since in the open position the medium flowing through the valve seat also exerts a force effect in the opening direction for the valve body. Since the closing process for a piston compressor takes place with pressure equilibrium or only a low flow of the medium, the spring force as the closing force is also of secondary importance here, since the magnetic force during the closing process begins to act on the spring arm at a time when the flow force acting in the opening direction sinks towards zero and when the valve is closed the higher pressure around the pressure chamber keeps the closing body in the closed position.
  • the armature is formed by a widened partial surface of the spring arm. This results in a significant reduction in the masses to be moved and, on the other hand, it is possible to arrange the electromagnets required for actuating the valve body with a small gap distance from the armature.
  • a base plate separating two pressure chambers is provided, which has a plurality of flow channels arranged at a distance from one another and that a spring arm with armature and valve body is provided for each flow channel at least on one side of the base plate and that at least one magnet intended to actuate all anchors. With such an arrangement, it is possible to provide a plurality of flow channels in a small installation space which, with a single diameter of only 10 mm, enable a throughput of the order of 1,000 to 1,600 l / h per flow channel.
  • Fig. 3 is a plan view of the valve assembly. the section III-III in Fig. 2,
  • Fig. 4 shows a modification of the spring arrangement.
  • Fig. 5 shows an application as a control valve for generating a negative pressure with the aid of pressure fluctuations.
  • the two pressure chambers 1 and 2 are connected to one another via a flow channel 4 arranged in the dividing wall 3 and through which a flowable medium, for example a gas, flows as a result of periodic pressure differences in the direction of the arrow 5.
  • the mouth 6 of the flow channel 4 into the pressure chamber 2 is designed as a valve seat 7, for example in the form of a conical or dome-shaped recess.
  • a valve body 8 is assigned to the valve seat 7 and is arranged at the free end of a resilient arm 9 clamped at the end.
  • the valve also has two electromagnets 11 and 12 with their pole faces 10 at a distance from one another and aligned with one another.
  • the area 13 of the resilient arm 9 assigned to the pole faces 10 serves here as an anchor.
  • the arrangement is such that when electromagnets 11, 12 are de-energized, the region 13 of the resilient arm 9 serving as an armature is in a central position, so that the valve body 8 is also at an average distance from the valve seat 7 .
  • the underlying electromagnet 11 serves as a closing magnet, while the overhead electromagnet 12 as
  • the opening magnet is used so that when the electromagnets are energized accordingly, the valve body 8 is either placed on the valve seat 7 and the valve closes or is lifted off the valve seat 7 and the valve is fully opened.
  • the valve body 8 is pressed onto the valve seat 7 in the manner of a check valve or tongue valve, even without support from the magnetic force of the closing magnet 11. If the pressure of the medium in the pressure chamber 1 is now increased, the medium will flow from the pressure chamber 1 into the pressure chamber 2 after the pressure equilibrium has been exceeded. In order to bring about a complete valve opening regardless of the level of the excess pressure in the pressure chamber 1, the opening magnet 12 is energized, for example, shortly before or when the pressure equilibrium is reached, so that at the beginning of the building overpressure in the pressure chamber 1, the flowable medium can flow through the flow channel 4 into the pressure chamber 2.
  • the opening magnet 12 can be de-energized shortly before and ultimately when the pressure equilibrium is reached and the closing magnet 11 can be energized, so that the valve body 8 is retracted by the action of the magnetic force on the valve seat 7 and so on to prevent the medium from flowing back from the pressure chamber 2 into the pressure chamber 1, which is now at a falling pressure.
  • the advantage here is that a very small distance can be set between the two pole faces and thus a direct effect of the magnetic force on the armature is possible.
  • FIG. 2 the application of the valve described above is shown schematically as an outlet valve on a piston compressor.
  • FIG. 2 in connection with FIG. 3 lets are in a partition 3.1 on the cylinder head 14, several flow channels 4, for example six flow channels, as shown in the illustration.
  • Fig. 3 reveals, evenly distributed over the circumference. Accordingly, six spring arms 9 with valve bodies 8 are also provided.
  • the spring arms are arranged radially inward and firmly clamped to the cylinder head 14.
  • the spring arms 9 are formed wider in their associated with the electromagnets 11 and 12 and serving as an anchor area 13, so that despite the manufacture as a stamped part, each spring arm is provided with a discrete anchor.
  • a head part 15 which on the one hand has an annular space 2.1 covering the mouths of the flow channels 4, which is provided with an outlet opening 16 and which, according to the description in accordance with FIG. Fig.
  • a central space 18 is provided above the partition 3, which is provided with an inflow channel 19.
  • the central space 18 stands above an inlet valve designed as a poppet valve
  • the inlet valve 20 is connected to a controllable actuator 21, so that the inlet valve 20 can be opened during the intake stroke and closed during the compression stroke.
  • the actuator 21 for the inlet valve 20 can also be configured here as an electromagnetic drive, which also how the closing magnet 11 and the opening magnet 12 can be controlled via a control device.
  • a radial-tangential alignment of the spring arms 9 is carried out, as is shown with reference to FIG. 4 in a top view corresponding to FIG. 3.
  • the widened portions 13 of the spring arms 9 functioning as anchors can, however, also be designed as circular sections concentric with the cylinder axis 17, so that ring-shaped opening and closing magnets can also be provided in this arrangement.
  • valve Since the structure and function of the valve described with reference to FIG. 1 allows very short switching times due to its small movable mass, it is also possible to use such a valve to generate a negative pressure with the aid of a pulsating gas flow fluctuating around a zero level in its pressure to use.
  • a valve arrangement of the type described with reference to FIG. 1 is connected to the air intake tract 22 of a piston internal combustion engine in such a way that the air intake tract 22 pressurizes the pressure chamber 1 in accordance with the illustration.
  • Fig. 1 forms and over a Flow channel 4.1 is connected to a system 26 that can be actuated by negative pressure, shown only schematically here, then in the illustrated assignment of the valve body 8.1, which is pressed onto the valve seat 7.1 via the spring arm 9.1 in the closed position, by actuating an electromagnet 12.1 functioning as an opening magnet, the valve in each case are then opened when a vacuum is present in the air intake duct 22 in the region of the junction 7.2 of the inflow duct 4.1 to the valve.
  • the electromagnet 12.1 can be energized via a corresponding control device 25, which detects the pressure profile of the air flow via a pressure transmitter 27 in the air intake tract 22.
  • the pressure transmitter 27 should be arranged as close as possible to the inflow duct 4.1 in order to detect the pressure level directly at the junction with the vacuum device 23.
