Title
(EN) PUMP AND CLEANING APPARATUS COMPRISING SAID PUMP
(FR) POMPE ET APPAREIL DE NETTOYAGE COMPORTANT LADITE POMPE
Abstract
(EN)
A pump comprises piston means (3) movable in a direction (D) , swash plate means (2) forming an angle with said direction (D) so as to reciprocate said piston means (3) in said direction (D) , elastic means (5) interacting with said swash plate means (2) to enable said angle to be modified; transmission means (19, 24, 25) is interposed between said elastic means (5) and said swash plate means. (2) for receiving a force (F) from said swash plate means (2) and transmitting a fraction (Fk) of said force (F) to said elastic means (5).
(FR)
L'invention concerne une pompe comportant un moyen (3) de piston mobile dans une direction (D), un moyen (2) de plateau oscillant formant un angle avec ladite direction (D) de façon à faire aller et venir ledit moyen (3) de piston dans ladite direction (D), un moyen (5) élastique interagissant avec ledit moyen (2) de plateau oscillant pour permettre la modification dudit angle ; et un moyen (19, 24, 25) de transmission interposé entre ledit moyen (5) élastique et ledit moyen de plateau oscillant (2) pour recevoir une force (F) dudit moyen (2) de plateau oscillant et transmettre une fraction (Fk) de ladite force (F) audit moyen (5) élastique.
