Abstract

The combined pump/motor consists of a stator (1) with a certain number of secondary chambers (4), and a rotor (2) with rollers (3) that adhere to the stator's inner surface. The pump and motor modes are controlled by the management of inlet (5) and outlet (6) ducts, which also vary the displacement of the machine. The shape of the rollers and secondary chambers combine to ensure that the rollers move relative to the rotor while using a minimum of energy.

Description

La présente invention concerne un dispositif mécanique agissant en tantThe present invention relates to a mechanical device acting as a

que moteur ou pompe et comportant peu d'éléments. Ce dispositif peut être adapté en moteur et/ ou pompe hydraulique ou pneumatique de cylindrée variable.  motor or pump and with few elements. This device can be adapted to motor and / or hydraulic or pneumatic pump of variable displacement.

Les dispositifs hydrauliques ou pneumatiques sont souvent employés pour des applications de fortes puissances. L'hydraulique de faible et moyenne puissance et ses applications sont en cours d'émergence. Il n'existe pourtant pas beaucoup d'éléments de conception simple permettant d'agir autant en tant que pompe 1 o hydraulique que de moteur hydraulique ou pneumatique pour ces gammes de puissances.  Hydraulic or pneumatic devices are often used for high power applications. Low and medium power hydraulics and its applications are emerging. There are, however, not many simple design elements to act as a hydraulic pump 1 o hydraulic or pneumatic motor for these power ranges.

Les dispositifs simples et de moyenne puissance pouvant combiner les modes moteur et pompe avec des cylindrées variables sont extrémements rares.  Simple and medium power devices that can combine the motor and pump modes with variable displacement are extremely rare.

Le dispositif selon l'invention permet de reeiiédier à ces inconvénients et de proposer un dispositif hydraulique qui permet d'entraîner un mécanisme sous l'action d'une force hydraulique et qui fournit lui-même un volume hydraulique quand J est soumis à l'entraînement d'un autre mécanisme. Dans le premier cas il fonctionne en mode moteur , dans le deuxième cas le dispositif fonctionne en mode pompe .  The device according to the invention makes it possible to reduce these disadvantages and to propose a hydraulic device which makes it possible to drive a mechanism under the action of a hydraulic force and which itself provides a hydraulic volume when J is subjected to the driving another mechanism. In the first case it operates in motor mode, in the second case the device operates in pump mode.

Le dispositif comporte en effet une première caractéristique constituée d'un stator cylindrique et un rotor cylindrique, l'axe de rotation du rotor étant parallèle à l'axe du stator.  The device comprises a first characteristic consisting of a cylindrical stator and a cylindrical rotor, the axis of rotation of the rotor being parallel to the axis of the stator.

La surface intérieure du stator est un cylindre de profil particulier qui subdivise l'espace entre le rotor et le stator en plusieurs chambres secondaires.  The inner surface of the stator is a cylinder of particular profile which subdivides the space between the rotor and the stator into several secondary chambers.

Le rotor est pourvu d'un ensemble de galets dont les extrémités sont mobiles dans des directions perpendiculaires à l'axe de rotation du rotor. Ces galets sont solidaires de la rotation du rotor et adhérent à la surface intérieure du stator. Au cours de la rotation du rotor les galets ouvrent un espace dans les chambres secondaires qu'ils découvrent, et ferment ce même espace en sortant des chambres secondaires précédemment parcourues.  The rotor is provided with a set of rollers whose ends are movable in directions perpendicular to the axis of rotation of the rotor. These rollers are integral with the rotation of the rotor and adhere to the inner surface of the stator. During the rotation of the rotor the rollers open a space in the secondary rooms that they discover, and close this same space leaving secondary rooms previously traveled.

Des voies de circulation situées à l'entrée et à la sortie des surfaces délimitant les chambres secondaires, permettent l'admission du fluide et son échappement.  Traffic lanes located at the entrance and exit of the surfaces delimiting the secondary chambers allow the admission of the fluid and its exhaust.

La rotation du rotor (2) dans le stator (1) permet aux galets (3) de 5 parcourir les différentes chambres secondaires. Chaque galet (3) ouvre alors un espace à partir de la conduite c'admission en parcourant la chambre secondaire. Ce même galet (3) ferme alors jusqu'à la conduite d'échappement, l'espace ouvert par le galet ayant parcouru précédemment la chambre secondaire (4).  The rotation of the rotor (2) in the stator (1) allows the rollers (3) to travel through the different secondary chambers. Each roller (3) then opens a space from the intake pipe by traversing the secondary chamber. This same roller (3) then closes to the exhaust pipe, the space opened by the roller having previously traveled the secondary chamber (4).

l o Les chambres secondaires (4) sont séparées et la gestion de l'admission (5) et de l'échappement (6) de chacune de ces chambres secondaires (4) permet le fonctionnement du système en 3 grandes configurations de cylindrées variables: 1. Tout ou partie des chambres secondaires en mode 15 pompe .  lo The secondary chambers (4) are separated and the management of the intake (5) and the exhaust (6) of each of these secondary chambers (4) allows the operation of the system in 3 large configurations of variable displacements: 1 All or part of the secondary chambers in pump mode.

2. Une partie des chambres secondaires en mode moteur et l'autre partie en mode pompe .  2. Part of the secondary chambers in motor mode and the other part in pump mode.

3. Tout ou partie des chambres en mode moteur .  3. All or part of the chambers in engine mode.

Selon les modes particuliers de réalisation: É Le dispositif peut être hydraulique ou pneumatique.  According to the particular embodiments: É The device can be hydraulic or pneumatic.

É Le nombre de chambres secondaires (4) est variable.  É The number of secondary rooms (4) is variable.

É Le nombre de galets (3) est variable.  É The number of rollers (3) is variable.

É L'adhérence des galets (3) sur la surface intérieure du stator (1) peut être assurée par différents dispositifs et peut être 25 commandée par un dispositif annexe.  The adhesion of the rollers (3) to the inner surface of the stator (1) can be provided by different devices and can be controlled by an auxiliary device.

Les dessins annexés illustrent l'invention La figure 1 représente le dispositif décrit de manière synthétique en coupe perpendiculaire à l'axe de rotation du moteur-pompe. La rotation du rotor étant vue dans le sens des aiguilles d'une montre.  The accompanying drawings illustrate the invention. FIG. 1 shows the device described in a synthetic manner in section perpendicular to the axis of rotation of the pump motor. The rotation of the rotor being seen in the direction of clockwise.

Le dispositif comporte un stator (1) et un rotor (2) caractérisés en ce que le rotor (2) est muni de galets (3) assurant une adhésion à la paroi intérieure du stator (1). Le stator (1) possède un profil cylindrique qui délimite des chambres secondaires (4), chaque 2885644 -;-chambre possède deux conduites; une d'admission (5) et une d'échappement (6) La gestion des admissions (5) et des échappements (6) des 5 différentes chambres secondaires (4) permet de faire varier la cylindrée du dispositif.  The device comprises a stator (1) and a rotor (2) characterized in that the rotor (2) is provided with rollers (3) ensuring adhesion to the inner wall of the stator (1). The stator (1) has a cylindrical profile which delimits secondary chambers (4), each chamber has two ducts; an intake (5) and an exhaust (6) The management of the admissions (5) and the exhausts (6) of the different secondary chambers (4) makes it possible to vary the cubic capacity of the device.

La mise en relation d'une ou plusieurs admissions (5) avec un ou plusieurs échappements (6) ferme les chambres secondaires (4) concernées. Ces dispositions réduisent d'autant, et 1 o proportionnellement au nombre de chambres secondaires (4) fermées, le volume de fluide nécessaire pour assurer la rotation du rotor (2) d'un angle équivalent au parcours d'une chambre secondaire (4).  The linking of one or more admissions (5) with one or more exhausts (6) closes the secondary chambers (4) concerned. These provisions reduce by the same amount, and 1 o proportionally to the number of closed secondary chambers (4), the volume of fluid necessary to ensure the rotation of the rotor (2) by an angle equivalent to the path of a secondary chamber (4). .

L'obturation conjuguée d'une ou plusieurs échappement (6) 15 combiné avec une rupture d'adhérence des galets (3) avec la surface intérieure du stator (1) permet aussi de faire varier la cylindrée utile.  The combined closure of one or more exhaust pipes (6) combined with an adhesion failure of the rollers (3) with the inner surface of the stator (1) also makes it possible to vary the useful displacement.

La forme des galets (3) assure l'étanchéité au moment de son passage devant les ouvertures des conduites d'admission (5) et d'échappement (6). Cette étanchéité permet d'assurer l'ambivalence de fonctionnement en mode moteur et/ou porlpe dans les chambres secondaires (4) ouvertes.  The shape of the rollers (3) seals at the time of its passage in front of the openings of the intake (5) and exhaust (6). This tightness makes it possible to ensure the ambivalence of operation in motor and / or door mode in the open secondary chambers (4).

Le nombre des galets (3), la forme et la disposition des chambres secondaires (4) et en particulier la disposition des voies d'admissions (5) et d'échappements (6) permet une séparation complète des accès entre ces derniers, et ce, a tout moment du cycle de fonctionnement du dispositif.  The number of rollers (3), the shape and arrangement of the secondary chambers (4) and in particular the provision of the admission channels (5) and exhausts (6) allows a complete separation of access between them, and this, at any time of the operating cycle of the device.

La disposition particulière des galets (3), leur forme et l'angle entre l'axe de déplacement des galets par rapport à un rayon de la coupe du rotor, assurent au galet (3) un déplacement optimal à l'ouverture d'une chambre secondaire, ou à sa fermeture en mode pompe et/ou en mode moteur .  The particular arrangement of the rollers (3), their shape and the angle between the axis of displacement of the rollers with respect to a radius of the cut of the rotor, ensure the roller (3) an optimal displacement at the opening of a secondary chamber, or when it is closed in pump mode and / or in motor mode.

Le nombre de galets (3) et de chambres secondaires (4) permet d'assurer une admission et un échappement continu dii dispositif par un décalage entre les positions des différents galets (3) dans les différentes chambres secondaires (4) La figure 2 représente le dispositif vu sous le même angle que précédemment.  The number of rollers (3) and secondary chambers (4) makes it possible to ensure continuous admission and exhaust of the device by an offset between the positions of the various rollers (3) in the different secondary chambers (4). the device seen from the same angle as before.

Le système fonctionne comme une pompe quand l'axe du rotor est entraîné par un autre dispositif Le rotor tourne alors sur son axe. Dans une chambre secondaire, un galet (3) ouvre un espace (el) qui aspire le fluide arrivant par la conduite d'admission (.5), pendant que le fluide ayant été admis précédemment dans l'espace (e2) est alors poussé vers la conduite d'échappement (6) Le fonctionnement en mode moteur dans une des chambres est similaire. Le fluide arrivant par la conduite d'admission (5) transfère son énergie au galet (3) ce qui a pour effet d'entraîner le rotor (3). Cette rotation ouvre alors l'espace (el) et réduit l'espace (e2) ayant alors pour effet de pousser le fluide s'y trouvant vers la conduite d'échappement.  The system functions as a pump when the rotor axis is driven by another device. The rotor then rotates on its axis. In a secondary chamber, a roller (3) opens a space (el) which sucks the fluid arriving through the intake pipe (.5), while the previously admitted fluid in the space (e2) is then pushed to the exhaust pipe (6) The engine mode operation in one of the chambers is similar. The fluid arriving through the intake pipe (5) transfers its energy to the roller (3) which has the effect of driving the rotor (3). This rotation then opens the space (el) and reduces the space (e2) then having the effect of pushing the fluid therein towards the exhaust pipe.
