Title (EN) SWASH PLATE PISTON PUMP/MOTOR
(FR) POMPE/MOTEUR A PISTON POUR PLATEAU CYCLIQUE
Abstract:
(EN) A swash plate piston pump/motor simple in structure, small in size, and ensuring rotation-in-tilt of the swash plate, wherein a swash plate receiving surface (7a) formed in a housing (1) is tilted at a given degree of angle with respect to the axis (2a) of a rotary shaft (2) and the distance from the axis of the rotary shaft (2) to the center (12a) of a ball (12) serving as the center of swing of the swash plate is reduced even when an angle of inclination of the swash plate (7) is made large.
(FR) Pompe/moteur à piston pour plateau cyclique de structure simple et de petite taille garantissant que le plateau cyclique effectue un mouvement de rotation avec basculement. La surface de contact (7a) dudit plateau, à l'intérieur d'un carter (1) bascule à un angle donné par rapport à l'axe (2a) d'un arbre tournant (2). La distance entre cet axe et le centre (12a) d'une sphère (12) servant de centre d'oscillation au plateau cyclique est faible, même si on élargit l'angle d'inclinaison dudit plateau (7).
