A pump with a body formed by two elements sealingly clamped together, between which is defined a central chamber in which a drive shaft carrying an eccentric is rotatably mounted. A plurality of cylinders which open into the central chamber are arranged radially around the shaft in one element of the body, and pistons which cooperate with the eccentric are slidably mounted therein. These cylinders are in communication with a supply chamber defined between the first and second elements. The supply chamber is annular in shape and is formed in a position radially outside the central chamber. At least one sealing member separates the supply chamber from the central chamber. At least one passage is formed in one of the elements to put the supply chamber into communication with the central chamber. An electrically-controlled device controls the flow of fluid through the passage in a predetermined manner.
