Abstract: front page image
(EN)This vane pump (100) comprises: a second pump body (20) which houses a cam ring (4), a spring (27) which energizes the cam ring (4) in a direction in which eccentricity with respect to the rotor (2) increases; a first pump body (10) and pump cover (15) which are positioned so as to clamp the second pump body (20); and a housing chamber (29) for housing the spring (27). A first interior surface (30) and second interior surface (40) which surround the spring (27) in the housing chamber (29) are respectively provided with supports (31, 41) that support the end (27a) of the spring (27) that is seated on the seating surface (20a) of the second pump body (20), and relief sections (32, 42) that are formed extending from the supports (31, 41) in the energizing direction of the spring (27) and are further away from the spring (27) than the supports (31, 41).
(FR)La présente invention concerne une pompe à palettes (100) comprenant : un second corps (20) de pompe destiné à loger un anneau à cames (4), un ressort (27) destiné à mettre sous tension l'anneau à cames (4) dans la direction d'augmentation de l'excentricité par rapport à un rotor (2) ; un premier corps (10) de pompe et un couvercle (15) de pompe placés de façon à serrer le second corps (20) de pompe ; et une chambre de logement (29) destinée à loger le ressort (27). Une première face intérieure (30) et une seconde face intérieure (40), entourant le ressort (27) dans la chambre de logement (29), sont respectivement munies de supports (31, 41) destinés à porter l'extrémité (27a) du ressort (27) assise sur la surface de portée (20a) du second corps (20) de pompe, ainsi que de sections de détente (32, 42) s'étendant à partir des supports (31, 41) dans la direction de mise sous tension du ressort (27) et étant plus éloignées du ressort (27) que les supports (31, 41).
