Pump system with rotary valve (2) comprising a pump (6) and a valve (8), the valve including a stator (18) comprising a stator body (32) and a plurality of stator fluid channels (34) connected to fluid ports (56) coupled to respective fluid supply and delivery lines, and a rotor (20) comprising a rotor body (36) and at least one rotor fluid channel (38). The stator body comprises a valve bearing surface (50) and the rotor body (36) comprises a complementary valve bearing surface slidably engaging the stator valve bearing surface, the rotor fluid channels (38) configured to be brought into fluid communication with stator fluid channels (34) as a function of the relative angular position of the rotor with respect of the stator about a rotor axis A. La présente invention concerne un système de pompe à soupape rotative (2) comprenant une pompe (6) et une soupape (8), la soupape comprenant un stator (18) comprenant un corps de stator (32) et une pluralité de canaux de fluide de stator (34) raccordés à des orifices de fluide (56) accouplés à des conduites d'alimentation et de distribution de fluide, et un rotor (20) comprenant un corps de rotor (36) et au moins un canal de fluide de rotor (38). Le corps de stator comprend une surface d'appui de soupape (50) et le corps de rotor (36) comprend une surface d'appui de soupape complémentaire mettant en prise de manière coulissante la surface d'appui de soupape de stator, les canaux de fluide de rotor (38) configurés pour être mis en communication fluidique avec des canaux de fluide de stator (34) en fonction de la position angulaire relative du rotor par rapport au stator autour d'un axe de rotor A.
