Definitions

  • the invention relates to a device for generating compressed gas, in particular for a compressed air brake system, according to the preamble of claim 1.
  • Such a device is described in connection with a compressed air brake system in the unpublished German patent application P 31 36 948.0.
  • a pressure control device (known under the name "Governor") that can be acted upon by the pressure of the storage container is used, inter alia, to switch the delivery phase of the air compressor to an idling phase.
  • the pressure control valve device connected between the storage container and the suction part of the compressor switches when a certain container pressure is exceeded in such a way that a switching piston arranged in the cylinder head of the compressor is acted upon by compressed air and the stroke movement of the switching piston triggered thereby pushes open the suction valve of the compressor by means of a piston tappet.
  • suction valves in the advantageous lamella construction is completely problem-free if the compressor is arranged in a device whose pressure control is carried out by means of a valve device in which a pressure exceeding a certain pressure level is blown off into the atmosphere in a known manner, i.e. H. the compressor continues to deliver compressed air in the idling phase so that the suction valve maintains its normal function during this phase.
  • the invention is therefore based on the object of creating a device of the type mentioned in which, despite pressure control by means of a "governor", the suction valve of the compressor can be designed as a lamella valve.
  • the use of a lamellar suction valve is advantageously made possible by a connection between the suction chamber and the compression chamber that is created during the idle phase, since the valve lamella can make the same opening and closing movements in the idle phase, like in the funding phase.
  • the degree of filling of the compressor is also improved by the additional valve of the idling valve device.
  • the device for generating compressed air according to FIG. 1 consists of a compressor shown in section, a storage container 8 and a pressure regulating device 9 consisting of a symbolically represented governor.
  • the sectional view of the compressor shows the part of a cylinder 16 with a compression chamber 1, a cylinder head 10 with a suction chamber 2 and a pressure chamber 4 and a valve plate 17 arranged between the cylinder 16 and the cylinder head 10.
  • the valve plate 17 carries the suction chamber 2 and Lamella suction valve 3 connecting compression chamber 1 and a pressure valve connecting compression chamber 1 and pressure chamber 4.
  • a compressed air outlet 5 of the cylinder head 10 establishes a connection between the pressure chamber 4 and the reservoir 8 via a line 7.
  • the valve plate 17 carries a further lamella valve which connects the suction chamber 2 and the compression chamber 1, which as an idle valve 12 is part of an idle valve device 11, 12.
  • the position of the idle valve 12 is located outside the cylindrical compression chamber 1 formed by the bore of the cylinder 16, a recess 15 of the cylinder 16 being connected to the compression chamber 1.
  • the idle valve 11, 12 includes an idle switching piston 11 with a plunger 11a for actuating the idle valve 12 in the same opening direction as the suction valve 3.
  • the idle switching piston 11 can be pressurized with compressed air.
  • the tension of a spring 11b acts on the idle switching piston 11 in the closing direction of the idle valve 12.
  • the idle valve consists of a poppet valve 18, the plate of which is acted upon in the valve closing direction by the tension of a spring 18a.
  • the components in FIG. 2 that correspond to FIG. 1 are numbered using the same numbers as in FIG. 1.
  • the schematic representation of the component connected to the compressor via the connections has been omitted in both FIG. 2 and FIG. 3.
  • FIG. 3 Another embodiment is shown in FIG. 3, in which the idle valve 19, designed as a lamellar valve, is located in a recess 20 in the valve plate 21 within the cylindrical compression space formed by the bore of the cylinder 21.
  • the suction valve does not appear on this sectional drawing.
  • the numbers of the components known from FIGS. 1 and 2 have been omitted in FIG. 3.
  • the spring 18a according to FIG. 2 can advantageously be designed such that the valve 18 does not open or only partially opens during the delivery phase of the compressor, which can mean an improvement in the service life of the valve.
  • the "governor" After reaching a certain pressure in the reservoir 8 conveyed by the air compressor, the "governor", which had previously been in the blocking position, switches over and compressed air flows from the reservoir 8 via the line 13 and the inlet 14 to the idling switching piston 11.
  • the stroke movement of the trigger thereby triggered Idle switching piston 11 pushes the idle valve 12 with the plunger 11a until the "governor” switches back again with a certain pressure drop in the reservoir 8 and the now depressurized, idle switching piston 11 is relieved with the aid of the voltage the spring llb returns to its initial position.
  • the idle valve 12 thus relieved likewise returns to its valve closed position during a compression stroke of the compressor piston.
