Definitions

  • the invention relates to a pneumatic component and particularly relates to an active pneumatic component.
  • the invention especially relates to a minimized combined component consisting of an oscillating membrane pump and a valve head having an inlet and an outlet and being switchable between different control states.
  • the invention relates to a pneumatic component for switching pneumatically switchable hydraulic bearings.
  • Such bearings are well known in the field of automotive engineering.
  • Such a pneumatically switchable hydraulic bearing is known for example from the published German patent application DE 32 10 731 A1 disclosing a pneumatic pressure chamber defined in a cup-shaped chassis-connection fitting underneath a compensating diaphragm of a basically conventional hydraulic bearing.
  • a variable pneumatic overpressure can be generated as a setting pressure directly influencing the stiffness of the hydraulic bearing by acting on the compensating diaphragm.
  • this pneumatic setting pressure is either externally generated and externally controlled or only externally generated and internally controlled with respect to the casing of the hydraulic bearing.
  • This internal controlling of the pneumatic setting pressure is effected by the compensating diaphragm itself, which opens and closes a relief valve according to the deformation caused by the damping fluid located in the working chamber of the hydraulic bearing.
  • the compensating diaphragm rolls up and down pushing a tappet of the valve to open the valve to a pneumatic pressure generator supplying constant pressure or releasing the tappet to close the valve by the restoring force of a spring. Therefore, according to the state of the art, an independent adjustment and switching of the hydraulic bearing can only be effected by a pneumatic pressure generator regulated by a real-time controller which are both located outside the component of the hydraulic bearing. This can obviously be attributed to the large size of these components which are dimensioned in accordance with the large pneumatic volumina to be moved.
  • the essential advantage which can be achieved with the component according to the invention is related to its simple and compact configuration. Due to the direct integration of the 3/2-port multiway valve in the oscillating membrane pump forming its top and accordingly due to the control of the valve operation by the pump and by means of the pump not only a miniature construction is achieved, but also not more than two lines of low voltage are required to control the switching states of the 3/2-port multiway valve as well as the states of the pump. This allows the direct integration of the pneumatic switching elements in the casing of the hydraulic bearing to be switched.
  • FIG. 1 shows a pneumatic component comprising the features of the invention in an axial section.
  • a 3/2-port multiway valve 2 and an oscillating membrane pump 3 are combined to a structural and functional unit.
  • the multi-way valve 2 comprises an inlet 4 and an outlet 5 .
  • the inlet 4 is connected with an inlet channel 6 having an inlet valve 7 .
  • the inlet 4 communicates with the outlet 5 of the component via a ventilation conduit 8 comprising a membrane valve 9 being closed by a biased spring 10 .
  • the outlet 5 of the component is connected with an outlet channel 11 comprising an outlet valve 12 .
  • the outlet channel 11 is closed by the restoring force of a spring.
  • the inlet channel 6 and the outlet channel 11 open into a pumping working chamber 13 of the oscillating membrane pump 3 .
  • the pumping chamber 13 is bounded by the oscillating membrane 14 .
  • the oscillating membrane 14 is driven by a plunger-type armature 15 of a reciprocating solenoid valve comprising a coil 16 .
  • the plunger-type armature 15 provides a drum-shaped cylindrical reinforcement 17 in central position of its axial extension. In a currentless or deenergized state of the magnetic coil 16 the cylindrical reinforcement 17 is supported in a defined rest position 20 by the restoring force of two restoring springs 18 , 19 .
