Abstract (en)
An electric pump has a containing tank (4) for an operating fluid (5), a feeding pump (6) to feed the operating fluid (5) from the containing tank (4) to a user, and a hydraulic circuit (7) to connect the containing tank (4), the feeding pump (6), and the user to one another; the containing tank (4) housing, on the inside, a floating piston (9) designed to divide the containing tank (4) into a first chamber (10) to contain the operating fluid (5) and into a second chamber (11) communicating with the outside and, hence, at atmospheric pressure.
