A pump including a stator (8), a rotor (6) comprising an axial extension (14,16) slidably and rotatably mounted at least partially in a rotor chamber (10) of the stator, and at least first and second valves between an inlet and the rotor chamber, respectively between the rotor chamber and an outlet (12), that open and close as. a function of at least the angular displacement of the rotor. The pump comprises interacting cam elements (42,44) on the rotor and stator and biasing means acting on the rotor for applying a force on the rotor in the axial direction of the stator cam element.
La présente invention concerne une pompe qui comprend un stator (8), un rotor (6) qui comprend un prolongement axial (14,16) monté de façon coulissante et rotative au moins partiellement dans une chambre de rotor (10) du stator, et au moins des première et seconde soupapes entre une entrée et la chambre de rotor, respectivement entre la chambre de rotor et une sortie (12), qui s~ouvrent et se ferment en fonction au moins du déplacement angulaire du rotor. La pompe comprend des éléments de came d~interaction (42,44) sur le rotor et le stator et des moyens de sollicitation qui agissent sur le rotor pour appliquer une force sur le rotor dans la direction axiale de l~élément de came de stator.
