Definitions

  • This invention relates to a combined two-function air compressor and jet washer device for non-professional use.
  • Low-capacity air compressors comprising a compressed air receiver supporting the unit for compressing air drawn from the atmosphere and the electric drive motor therefore, and jet washers comprising a pump which draws water from a feed line and delivers it to a hose provided at its end with a jet gun, are both widely used.
  • devices comprising in a single unit an electric motor provided with means which enable it to be selectively connected to an air compressor and to a jet washer pump which are situated on the same support, preferably consisting of the compressed air receiver, as described in Italian patent application MN95A000008 in the name of the present applicant.
  • the object of the present invention is to provide a unit able to act both as an air compressor and as a jet washer, in which to pass from one function to the other the operator has to operate only one control, and in which disengagement of the function not to be used is automatically ensured.
  • Said object is attained within the framework of a reliable, simple and economical mechanical arrangement suitable for private use.
  • a combined device for the two functions of air compressor and jet washer comprising an electric motor with two directions of rotation provided with means for its selective connection to the air compression unit and to the jet washer pump, the shaft of said electric motor being connected respectively to the air compression unit and to the jet washer pump by two free wheels mounted with opposite dragging directions.
  • the reference numeral 1 indicates the electric motor with two directions of rotation mounted, as in the case of the other components to be described, on a frame 2 fixed to the top of the compressed air receiver 3.
  • the shaft end 4 is connected via the free wheel 41 to the jet washer pump 6, the suction side of which can be connected to a water feed line by means of the hose 7, its delivery side being connected to the hose 8 which terminates with the jet gun 9.
  • the shaft end 5 is connected via the free wheel 51 to the unit 10 compressing the air to be fed to the receiver 3, said free wheel 51 being mounted with its dragging direction opposite that of the free wheel 41.
  • the device hence operates as a jet washer because whereas the pump 6 is rotated, the air compression unit 10 is at rest.
  • the shaft of the electric motor 11 has only one output end 110, which is permanently connected to the shaft 111 of the air compression unit 16.
  • the shaft 111 is connected via the free wheel 12 to the jet washer pump 13 and, via the interposed free wheel 14 having the opposite dragging direction to the free wheel 12, carries the cam 15 (see Figure 3) which operates the connecting rod 161 of the air compression unit 16.
  • Figure 4 shows a further embodiment in which the output shaft of the electric motor 17 has two ends 171 and 172 emerging from the casing.
