Abstract

CETTE UNITE MOTRICE COMPORTE UN PISTON DE TRAVAIL 3 ET UN ORGANE DE TRAVAIL 4 DEPLACABLES SEPAREMENT. L'ORGANE DE TRAVAIL PEUT ETRE CONSTITUE PAR UNE TIGE DE PISTON OU PAR UN ARBRE D'ENTRAINEMENT EN ROTATION. LE PISTON DE TRAVAIL PEUT ETRE ACCOUPLE A L'ORGANE DE TRAVAIL DANS LA DIRECTION DU TRAVAIL (DIRECTION X) POUR TRANSMETTRE L'ENERGIE MOTRICE; IL PEUT EN ETRE DESACCOUPLE DANS LA DIRECTION OPPOSEE (DIRECTION Y). UN ACCUMULATEUR D'ENERGIE 14, 16 EST RELIE A L'ENCEINTE PRIMAIRE 10. LE VOLUME DE L'ENCEINTE SECONDAIRE 11 EST DETERMINE PAR UN PISTON AUXILIAIRE.THIS DRIVE UNIT INCLUDES A WORKING PISTON 3 AND A WORKING MEMBER 4 SEPARATELY MOVABLE. THE WORKING MEMBER MAY BE A PISTON ROD OR A ROTATING DRIVE SHAFT. THE WORKING PISTON MAY BE COUPLED TO THE WORKING ORGAN IN THE DIRECTION OF WORK (DIRECTION X) TO TRANSMIT THE DRIVING ENERGY; IT MAY BE DISCOUPLED IN THE OPPOSITE DIRECTION (DIRECTION Y). AN ENERGY ACCUMULATOR 14, 16 IS CONNECTED TO THE PRIMARY ENCLOSURE 10. THE VOLUME OF THE SECONDARY ENCLOSURE 11 IS DETERMINED BY AN AUXILIARY PISTON.
