摘要： A vacuum pump has inside the pumping chamber valves intended to control the operation by opening and closing during the suction and delivery cycle of the pump. The valves or parts connected thereto are formed at least in part by a ferromagnetic material. A magnetic inductor is applied outside a wall, formed by a non ferromagnetic material, of the pumping chamber of the pump, and inside the pumping chamber are installed conducting elements of ferromagnetic material, for conducting magnetic flow produced, by the inductor, up to polar points close to the positions taken in the conditions of inactivity by the valves, so as to magnetically attract the valves (10,20) in an inactivity position when the inductor is operated, and thus stop the pneumatic operation of the pump without stopping its motion which then becomes idle.

摘要： A valve intended to disconnect, in specific circumstances, the braking of the front wheels, and/or of a trailer whose braking system is connected through a trailer braking valve, for the braking system of a farm tractor or similar vehicle which includes two master cylinders, operated by two separate braking pedals, directly controlling the braking of the rear wheels, and controlling the braking of the front wheels and/or the braking device of the trailer through the disconnection valve. The disconnection valve includes a body, first and second inlet connections connected to the two master cylinders, and a delivery connection connected to a braking circuit of the front wheels and/or to the trailer brake valve. The valve body has a bore wherein is installed one movable piston subjected to the action of pressure applied to the first inlet connection.

摘要： A fluidic machine having a fixed body (1,2), an external orbital member (7) which is rotatable around a first rotational axis and has internal gear teeth comprising a first teeth number, a transmission member (3) rotatable around a second rotational axis not coincident with the first rotational axis, an internal orbital member (5) supported by the transmission member (3), having external gear teeth comprising a second teeth number different from the first teeth number and meshing with the internal gear teeth of the external orbital member (7), thus determining among the gear teeth of the two orbital members (5,7) spaces whose volume is variable during the rotation. According to the invention, one of the orbital members (5,7) is mounted axially displaceable and it is pushed by an elastic push member (6) in the direction producing a more extended engagement with the other orbital member (7,5), and a piston (8), which is mounted displaceable within the non-axially displaceable orbital member and rests against the axially displaceable orbital member, is subjected, on the side opposite the axially displaceable orbital member, to the pressure of the high pressure connection (21), whereby the axially displaceable orbital member is pushed by the pressure of the high pressure connection (21) to withdraw against the action of the elastic push means (6), within the supporting part, this latter along with the piston delimiting the operatively active portion of the two mutually meshing orbital members (5,7), namely the swept volume of the fluidic machine, this swept volume decreasing as the pressure of the high pressure connection increases.
