摘要： Dans une pompe duplex à piston (10) à commande hydrostatique pour l'entraînement de liquides chargés de particules abrasives, de boues coulantes, d'émulsions ou d'autres liquides semblables, chaque piston plongeur (14) est couplé à une unité hydraulique de piston-cylindre (16a; 16b) à effet double, dont l'admission est commandée par un milieu hydraulique de façon à ce que la course de ses pistons suive à chaque fois une direction inverse. L'extension (b) de la course de travail maximale (a+b) des unités de piston-cylindre (16a; 16b) est dimensionnée pour être supérieure à la course de travail (a) du piston plongeur (14) de la pompe d'alimentation couplée respective (12a; 12b), de telle façon que lors du déploiement total de la course de travail maximale des unités de piston-cylindre (16a; 16b) les pistons plongeurs (14) sortent entièrement du cylindre plongeur (22) correspondant. Lors du fonctionnement normal de la pompe, la course de retour des unités hydrauliques de piston-cylindre (16a; 16b) est limitée à une extension (a) correspondant à la course de travail (a) des pistons plongeurs. Alternativement, il est possible de commander les unités hydrauliques de piston-cylindre (16a; 16b) de façon à les faire exécuter une course de retour maximale (a+b), ce qui permet, lorsqu'un démontage se fait nécessaire, de sortir les pistons plongeurs (14) de leurs cylindre respectif (22).

摘要： A free piston device, comprises a housing with a cylindrical inner wall having a first wall opening and a second wall opening; a cylindrical piston movable in axial direction and rotatable around its longitudinal axis; the piston comprising a first skirt forming a first chamber, said first skirt having at least a first opening in the form of a hole through the wall of the skirt for allowing passage of a fluid directly into or out of said chamber; control means for controlling axial and angular movement of said piston; sensing means for providing signals related to the axial position and/or the angular position of the piston; a digital control unit for rotating the piston around its longitudinal axis in synchronism with its axial movement.

摘要： An internal combustion engine (23) includes: a crankcase (24) that supports a crankshaft (33) rotatably about a rotational axis (28); a cylinder block (25) connected with the crankcase (24) and including at least one pair of cylinders (42a) that sandwich a valve chamber (45) therebetween in an axial direction of the crankshaft (33), the valve chamber (45) housing therein a valve actuating mechanism (48) that connects a camshaft (49) to the crankshaft (33); a detected member (78) disposed between crank pins (38) corresponding to the pair of cylinders (42a), the detected member (78) rotating integrally with the crankshaft (33); and a detection sensor (83) disposed to face a trajectory of the detected member (78) and generating a pulse signal in accordance with movement of the detected member (78). Accordingly, the internal combustion engine (23) can avoid displacement of a nearby part and enlargement of the crankcase (24) as much as possible, while allowing the detected member (78) to be increased in size.

摘要： The invention relates to a hydraulic device comprising an autonomous electronic sensor assembly that has at least one miniature sensing element. Sensing elements of this type require a minimal amount of space. It is especially preferred if the sensor assembly has at least one miniature transmitter. As the hydraulic device does not then require any sensitive electric cables for signal transmission, the reliability of its monitoring capabilities is optimised.
