Abstract: An apparatus for frothing milk includes: a container for milk to be frothed; a steam source; a steam ejector device including a first inlet line in fluid communication with the container and a second inlet line in fluid communication with the steam source, the steam ejector device injecting steam into the milk to obtain a milk and steam mixture, the steam ejector device including an outlet line for the milk and steam mixture; an air intake in fluid communication with the outlet line of the steam ejector device; and a pump located downstream of the steam ejector device for drawing the mixture of milk and steam and air coming from the outlet line of the steam ejector device, the pump forming a froth of the mixture of milk and steam delivering the froth along a delivery line.

Abstract: An improved screw-spindle pump, particularly for cooling systems, includes a first screw, a second screw and a pump housing, inside which the first screw and the second screw are rotatably housed between the first screw, the second screw and the pump housing, being defined pumping chambers adapted to move, as a consequence of the rotation of the first screw and the second screw, a fluid from a suction area to a delivery area of the pump. The pump housing housing the first screw and the second screw is made in one piece.

Abstract: A device for emulsifying liquid or solid products, in particular food products such as milk or ice cream, including a pump having at least one suction duct adapted for sucking a product to be emulsified and an emulsifying gas, and a delivery duct adapted for dispensing an emulsion obtained starting from the product to be emulsified and from the emulsifying gas, where the pump has a double worm screw arranged between the suction duct and the delivery duct, the double worm screw being adapted for emulsifying the product and the gas to obtain the emulsion and to push the product, the gas and/or the emulsion with a flow substantially parallel to the axis of the screws of the double worm screw from the suction duct to the delivery duct.

Abstract: A hydraulic pump is described, comprising at least one inlet duct for a fluid, at least one outlet duct for the fluid and at least one pumping unit interposed between the inlet and outlet ducts. At least one multifunction valve is interposed between the inlet duct, upstream of the pumping unit, and the outlet duct, downstream of the pumping unit, which valve is configured to divert the flow of fluid from the inlet duct to the outlet duct without the fluid flowing into the pumping unit. The multifunction valve comprises a valve body that defines an inner bypass channel in which a shutter element is axially movable, an actuator member operatively associated with the shutter element and configured to move it from a closing position to an opening position of the bypass channel, and an elastic contrast element operatively associated with the shutter element and configured to keep it in the first closing position of the bypass channel when such shutter element is not actuated by the actuator member.

Abstract: A containment assembly for a pump provided with at least one pumping group and with 5 at least one power transmission system to such a pumping group. The containment assembly includes a substantially cylindrical containment vessel provided with an opening at one of the ends thereof, configured to at least 10 partially enclose the pumping group and the respective power transmission system. The containment assembly also includes at least one closure plate, sealably coupled with the containment vessel at the open end thereof and configured to hermetically enclose, in 15 cooperation with such a containment vessel, the pumping group and the respective power transmission system. On a predetermined contact portion between the containment vessel and the closure plate at least one wave spring is provided, configured to keep the pumping group 20 dynamically under compression by means of the closure plate.

Abstract: The invention describes a method for adjusting the pressure in a pumping system (10) of a motor vehicle with an internal combustion engine. The pumping system (10) comprises one or more pumps, wherein each pump is provided with a respective driving motor, and at least one programmable electronic control unit (12). The method comprises the steps of adjusting or mapping the programmable electronic control unit (12) of the pumping system (10), carried out by setting a set of predefined operating parameters of each pump in the programmable electronic control unit (12) of the pumping system (10), and of controlling the operation of the pumping system (10), wherein such control is an open-loop control and wherein the control action is independent from the values of the output parameters of the pumping system (10).

Abstract: A pump (10) comprising a casing (12) that encloses a pumping group (14). On the casing (12) at least one inlet conduit (F) and at least one outlet conduit are obtained. The pumping group (14) comprises a pair of mutually coupled gears defining a pump chamber. A first support shaft (16) is operatively connected to an actuator assembly (18) so that the first gear can operate as a driving gear to set the second gear in rotation. The pump (10) comprises at least one element (20) for compensating the increase in volume of the fluid (F) and/or the increase in the pressures inside such a pump (10). The element (20) for compensating the pressure/volume is at least partially manufactured from a shape memory metal alloy having superelastic properties.

Abstract: A positive-displacement pump (10) of the type comprising a driving gear (12) and a driven gear (14) perfectly coupled together and each mounted on a respective support shaft (16, 18). The driving gear (12) is operatively connected to a motor (20) to set the driven gear (14) in rotation and generate the pumping action on a fluid. The gears (12, 14) are contained in a chamber (40) provided with a closing plate (42). The support shafts (16, 18), the central body (38) of the pump (10), the chamber (40) that contains the gears (12, 14), the closing plate (42) of such a chamber (40), an inner magnet (36) and the base of the rear body (28) of the pump (10) are in turn housed inside a casing (30) of the pump (10).
