Abstract
A pump includes a chamber defined by a piston movable in a body comprising an intake opening able to communicate with the chamber and a first non-return member authorizing passage of fluid from the opening toward the chamber, and prohibiting the passage from the chamber toward the opening. An expulsion opening is between the chamber and a duct, and a second non-return member authorizes passage of fluid from the chamber toward the duct, and prohibits passage from the duct toward the chamber. The body includes a discharge opening communicating with the duct and able to communicate with the opening, and a third non-return member movable between an open position, in which the duct communicates with the opening, and a closed position prohibiting the passage of fluid between the duct and the opening. The pump includes a member to move the third non-return member.
