Abstract

The cylinder is divided into two parts by a central partition (4). The partition supports the common piston rod (6) which carries two pistons (7,8). Exhaust gases at the cylinder outer end operate against the inlet combustion air at the rod side of the pistons. Air is admitted centrally through the passage (11) leading to the valves. Air is exhausted through the outlet passage (16) and exhaust gases are expanded in the cylinder space (19). The valves are actuated through a linkage (23).

Description

Dispositif de compresseur pour l'alimentation des moteurs å combustion interne et autres. Compressor device for powering internal combustion engines and others.

I1 est destiné à améliorer le rendement de ces moteurs tout en réalisant des économies d'énergie. I1 is intended to improve the efficiency of these engines while achieving energy savings.

Dans les dispositifs connus on utilise des turbo-compresseurs actionnés par les gaz d'échappement des moteurs pour la suralimentation de ces derniers. Mais dans ces installations la compression de l'air par le turbo-compresseur est difficile à synchroniser avec l'aspiration des cylindres du moteur car le débit et la pression de l'air varient avec la vitesse du compresseur et l'on n'y parvient que par des moyens compliqués. In known devices, turbo-compressors actuated by the exhaust gases of the engines are used for the supercharging of the latter. But in these installations, the compression of the air by the turbo-compressor is difficult to synchronize with the suction of the engine cylinders because the air flow and pressure vary with the speed of the compressor and there is no only succeeds by complicated means.

Le dispositif suivant l'invention supprime ces inconvénients et permet d'augmenter et d'améliorer le taux de remplissage des cylindres en le rendant proportionnel à la vitesse de rotation des moteurs à combustion interne et autres. The device according to the invention eliminates these drawbacks and makes it possible to increase and improve the filling rate of the cylinders by making it proportional to the speed of rotation of internal combustion engines and the like.

I1 se caractérise par l'application nouvelle d'un compresseur à piston synchronisé avec l'aspiration des cylindres et actionné par l'énergie résiduelle des gaz d'échappement. I1 is characterized by the new application of a piston compressor synchronized with the suction of the cylinders and actuated by the residual energy of the exhaust gases.

Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention
La figure 1 montre vu en coupe longitudinale le compresseur à piston dans 2 sections perpendiculaires.In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows a longitudinal section view of the piston compressor in 2 perpendicular sections.

Les figures 2 et 3 représentent des variantes constructives d'un dispositif similaire pour des applications equi- valentes. Figures 2 and 3 show constructive variants of a similar device for equivalent applications.

Le compresseur fig 1, est constitué par un cylindre 1 avec parois d'extrémités 2, 3 et cloisonnement axial 4. The compressor fig 1, is constituted by a cylinder 1 with end walls 2, 3 and axial partitioning 4.

Le cloisonnement axial forme, par un alesage axial, le palier 5 dans lequel coulisse l'arbre 6. Sur cet arbre sont montés les deux pistons opposés 7, 8. The axial partition forms, by an axial bore, the bearing 5 in which the shaft 6 slides. On this shaft are mounted the two opposite pistons 7, 8.

Ces pistons se déplacent dans la cylindrez où au cours de leur déplacement ils dégagent ou occupent les secteurs 9 et 9' et 10 et 10'.  These pistons move in the cylinder where during their movement they clear or occupy sectors 9 and 9 'and 10 and 10'.

Dans les secteurs 9, 9' les gaz d'échappement du moteur se détendent alternativement en comprimant l'air, dans les secteurs 10 et 10' et s'échappent en aspirant l'air. In sectors 9, 9 'the engine exhaust gases alternately expand by compressing the air, in sectors 10 and 10' and escape by sucking in air.

L'admission d'air s'effectue par les conduits perpendiculaires 11, 12 pourvus de cl-apets 13, 14.  The air intake takes place through the perpendicular ducts 11, 12 provided with valves 13, 14.

La distribution d'air comprimé s'effectue par les conduits 15, 16 également perpendiculaires. The distribution of compressed air is carried out through conduits 15, 16 also perpendicular.

Le conduit 15 est pourvu de deux clapets 17, 18. The conduit 15 is provided with two valves 17, 18.

Les parois 2, 3 du cylindre principal comportent un conduit d'admission des gaz d'échappement moteur 19 et un conduit d'évacuation 20 de ces gaz. The walls 2, 3 of the main cylinder comprise an intake duct for the engine exhaust gases 19 and an exhaust duct 20 for these gases.

Les gaz d'échappement du moteur sont admis par les soupapes 21, 21'. Ils sont évacués des sections de cylindre 9, 9' par les soupapes 22, 22'. The engine exhaust gases are admitted through the valves 21, 21 '. They are evacuated from the cylinder sections 9, 9 'by the valves 22, 22'.

Les soupapes sont commandées par des jeux de culbuteurs 23, 23' commandés par un arbre à cames 24 actionné par la rotation du moteur. The valves are controlled by sets of rocker arms 23, 23 ′ controlled by a camshaft 24 actuated by the rotation of the engine.

Les clapets d'admission et de distribution d'air peuvent être remplacés par des soupapes. The air intake and distribution valves can be replaced by valves.

Il est égarement possible d'utiliser des secteurs de cylindres 9, 9', ou 10, 10' comme chambres motrices ou de compression, c'est à dire en inversant les admissions d'air et de gaz d'échappement. It is also possible to use cylinder sectors 9, 9 ', or 10, 10' as driving or compression chambers, that is to say by reversing the air and exhaust gas intakes.

Suivant la variante d'exécution, représentée sur la fig 2, on utilise toujours le même principe. According to the variant of execution, represented in FIG. 2, the same principle is always used.

Les pistons 25, 26 sont toujours montés en opposition et coulissent dans les cylindres 27, 28 avec secteurs 27' 28'. Ils sont reliés à un vilebrequin 29 par les manivelles 30 et 31. Les parois 32, 33, 34, 35 sont pourvues de conduites d'admission équivalentes à celles représentées sur la figure 1 avec les mêmes jeux de clapets et de soupapes pour les admissions, évacuations et distributions de gaz d'échappement moteur et d'air. The pistons 25, 26 are always mounted in opposition and slide in the cylinders 27, 28 with sectors 27 '28'. They are connected to a crankshaft 29 by the cranks 30 and 31. The walls 32, 33, 34, 35 are provided with intake pipes equivalent to those shown in FIG. 1 with the same sets of valves and valves for the admissions , exhaust and distribution of engine exhaust gas and air.

Le vilebrequin 29 est libre ou actionné par le moteur à combustion interne. The crankshaft 29 is free or actuated by the internal combustion engine.

La figure 3 représente toujours une variante d'exécution du même dispositif. I1 est constitué par les pistons parallèles 36, 37 coulissant dans les cylindres 38, 39 également juxtaposés et verticaux. Ils sont reliés par les bielles et manivelles 41, 42 au vilebrequin 40commandées par le moteur. Le cylindre 38 est le cylindre moteur actionné par les gaz d'échappement et le cyindre 39 celui de compression de l'air. Figure 3 always shows an alternative embodiment of the same device. I1 is constituted by the parallel pistons 36, 37 sliding in the cylinders 38, 39 also juxtaposed and vertical. They are connected by the connecting rods and cranks 41, 42 to the crankshaft 40 controlled by the engine. The cylinder 38 is the engine cylinder actuated by the exhaust gases and the cylinder 39 that of the air compression.

Le nombre des cylindres opposés, justaposés, ou même montés en étoile n'est pas limitatif. The number of opposite cylinders, just seated, or even star-shaped is not limiting.

Ce dispositif compresseur à piston peut équiper tous les moteurs à combustion interne à essence (carburation ou injection), diesels, à piston ou autres avec amélioration des rendements. This piston compressor device can equip all internal combustion petrol (carburetion or injection), diesel, piston or other engines with improved yields.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite de équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents as, moreover, the materials used for their manufacture, without thereby changing the general design of the invention which has just been described.
