Definitions

  • the present invention relates to a compressor construction starting from the transformation of an alternative heat engine, to obtain a piston compressor of the type under sealed enclosure.
  • the invention proposes to provide a compressor structure retaining the component parts of a more expensive alternative heat engine, more precisely the cylinder block, movable assembly, oil pump which are directly usable in the compressor application, structure according to which the cylinder block is enclosed in a container made of sealed and pressure-resistant welded sheet steel.
  • the invention relates more precisely to a piston compressor structure of the sealed enclosure type, comprising a specific compressor cylinder head completed by a set of parts of the internal combustion engine as standard, and driven through the sealed enclosure by an external motor.
  • said compressor being fixed to the cover of the sealed enclosure by its cylinder head
  • this compressor being according to a first embodiment characterized in that it is fixed to the cover by a first connecting piece fixed at the end of the cylinder head and by a second connecting piece fixed at the same end of the cylinder block and bearing on the support of the compressor drive members through the cover of the sealed enclosure.
  • a second embodiment of the compressor according to the invention is characterized in that the cover itself consists of the cylinder head provided with suitable flanges and covers, its cylinder block being fixed to said cylinder head in the sealed enclosure where it connects to the drive means passing through the enclosure.
  • Additional fixing means fixed to the mounting plates of accessories of the basic motor not used for the compressor, connect the latter to the fixing points of the sealed enclosure, in particular for the most important models.
  • the intake will be carried out directly on the enclosure, the compressor suction directly in it or by an external outlet directly connected to the cylinder head of which it constitutes an element for fixing to the enclosure.
  • the drive is carried out by means of a flexible coupling housed inside the enclosure, the coupling being driven by a short intermediate shaft, journalled by means of bearings and provided with sealing means.
  • the coupling preferably flexible, of the type with two coaxial pinions connected by chain, will be connected to the intermediate shaft by a seal of the type with sliding grooves, in particular for the models of the type suspended on the cylinder head forming a cover, which facilitates mounting.
  • the cylinder block 2 has been freed from the accessories specific to operation with a thermal engine (supply, distribution, ignition, cooling, flywheel, etc.) and provided with a specific cylinder head 3 with automatic valves (for refrigerant for example).
  • the housing / cylinder head assembly is introduced into an enclosure 1 made of thick sheet steel, assembled by welding, the cover 4 of which keeps the housing / cylinder head assembly in position as described below: plate 10, welded to the cover 4, is bolted by means of studs 11 to the front end of the cylinder head 3.
  • the plate 10 allows, on the other hand, the passage of the delivery pipe 6.
  • a part carries -steel 15 is welded to the cover 4, its axis being coincident with that of the crankshaft 13.
  • a connecting piece 12, bolted to the cylinder block 2 is supported on a bearing surface of the bearing 15 and collects the overturning torque during the compressor operation.
  • the cover 4 is itself made integral with the enclosure 1 by the bolts 24, by means of the flanges 19 welded on 1 and on 4.
  • the compressor drive is carried out by means of a flexible coupling 14 fixed at place and place of the flywheel on the fixing plate or cake of the crankshaft 13.
  • the coupling 14 drives an intermediate shaft 20, which carries the rotary seal 16 held in place by the cover 17.
  • the coupling 14 can advantageously be of the type with two coaxial chain sprockets.
  • stretchers 18 can be mounted on the tam side bolts 7 for fixing the engine.
  • the stretchers consisting of a cylindrical rod with a conical end, engage in the chamfered circular orifices of the parts 8 welded to the bottom 26 of the enclosure 1, thus eliminating the overhang.
  • a shoe or roller 9 can facilitate the installation of the cylinder block / cylinder head assembly in enclosure 1.
  • the stretchers 18 can be fixed in position 22 on the rear part of the cylinder head ( Figure 2) or in position 23 on the cylinder block (in place of the water pump, or the timing cover, or any other accessory originally fitted to this face of the engine), as shown in Figure 3.
  • the intake manifold 5 can be welded in any favorable location of the enclosure 1, for example on the bottom 26 ( Figures 1 and 2). Otherwise, the tubing 5 is then necessarily fixed to the bottom 26 so that its inner end enters a suitable orifice in the cylinder head 3, the seal being produced by means of a seal 25 ( Figure 3).
