Definitions
- the present invention due to the collaboration of Mr. Institut LEORAT, relates to a compressor construction from the transformation of an alternative heat engine, in particular for a refrigerant compressor of the open type, semi-hermetic or hermetic.
- This invention is applicable to most types of reciprocating engines, whether initially diesel or petrol, air or water cooled, jacketed or not, provided they are originally fitted with removable cylinder heads .
- the present invention specifically proposes to carry out the transformation of an alternative heat engine into a compressor, in particular a refrigeration compressor, so as to take advantage of an advantageous low cost resulting from the mass production of the main component parts of a heat engine, all respecting the functional constraints specific to the compressors.
- the invention essentially consists, while retaining, among the constituent parts of an alternative heat engine, those (among the most expensive, precisely cylinder cylinders, mobile equipment, oil pump) which are directly usable in the compressor application , enclose the cylinder block in a container made of sealed, pressure-resistant welded sheet steel and make the essential cylinder block / container connections essential (mechanical drive of the compressor, suction and discharge of working fluid, etc.) ).
- the invention relates to a piston compressor structure of the sealed enclosure type, characterized in that its specific cylinder head is supplemented by a set of parts of the internal combustion engine as standard, the compressor drive being carried out through the sealed enclosure by an external motor.
- the compressor is generally fixed to the cover of the sealed enclosure by its cylinder head, either by a connecting piece fixed at the end of the cylinder head and by a connecting piece fixed at the same end of the cylinder block and bearing on the support of the members.
- driving the compressor through the cover of the sealed enclosure i.e. the cover itself consists of the cylinder head fitted with flanges and appropriate covers, its other members being fixed to said cylinder head in the sealed enclosure where they are connected 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 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 cillasse of which it constitutes a fixing element 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.
- FIG. 1 represents a preferred embodiment of the invention
- FIGS. 2 and 3 illustrate variants of the embodiment represented by FIG. 1,
- FIG. 1 the cylinder block 2 has been freed from the accessories specific to operation with a heat 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 a container 1 made of thick sheet steel, assembled by welding, the cover 4 of which maintains the position. of the housing / cylinder head assembly as described below: a 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 discharge pipe 6.
- a bearing support part 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 operation of the compressor.
- the cover 4 is itself made integral with the container 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 in 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 be advantageously of the type with two coaxial sprockets with Brampton chain.
- stretchers 18 can be mounted on the buffers side 7 for fixing the motor.
- the stretchers consisting of a cylindrical rod with a conical end, engage in the circular chamfered orifices of the parts 8 welded to the bottom 26 of the container 1, thus eliminating the overhang.
- a shoe or roller 9 can facilitate the installation of the cylinder block / cylinder head assembly in the container 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 container 1, for example on the bottom 26 ( Figures 1 and 2).
- 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).
- the container 30, cylindrical has at its upper part a rectangular opening constituted by a large section frame 36 welded to the container.
- the dimensions of this frame 36 are such that the cylinder block 2, with the coupling14 previously fixed on the oil cake of the crankshaft 13, can be lowered through this frame into the container 30.
- the cylinder head 31 secured to the cylinder block 2 thanks to the studs 35 rests on its underside by its sole 39 on the frame 36, to which it is fixed by the bolts 37.
- the cylinder head 31 is closed by the cover 33, secured by the bolts 34, which allows direct access to the valves.
- the arrangement of the coupling 14 is similar to that described with respect to the variant of FIG. 1, except that: - the connecting piece 12 no longer has any reason to be,
- the shaft 20 drives the coupling 13 by means of sliding grooves, which makes it possible to slide the shaft 20 into position when the cylinder block 2 is in place in the container 30, the coupling 14 having been previously fixed on the crankshaft cake 13.
- the inlet 32 and outlet 38 pipes are most conveniently arranged on the lateral faces of the cylinder head, as in the example in FIG. 3.
