Percolator unit according to claim 2, wherein the driving of the screw by the gear motor occurs by way of a rapid coupling, the driving nut mounted on the movable plate comprising a pressure box, the stopping and reversing of the movement being controlled directly by an electronic torque sensor controlling the pressure so as to eliminate micro-switches normally used. 4. Percolator unit according to claim 1, wherein the driving system comprises a double action cylinder actuated by way of pressurized water originating from the pump that also furnishes the water adapted for infusing the hot beverage, and that controlling the position of the cylinder, as well as the quantity of water to be infused, occurs due to a single flow meter associated with a programmable system actuating electrovalves. 5. Percolator unit according to claim 1, wherein the counter-plunger is driven by an annular shoulder arranged at the bottom of the infusion chamber and acting either on one of the head and two abutments affixed to said counter-plunger. 6. Percolator unit according to claim 5, wherein the counter-plunger comprises two flexible tongues butting against an annular boss affixed to the flow conduit so as to restrict its movement at the beginning of the extraction phase. 7. Percolator unit according to claim 1, wherein, for the infusion phase, hot water enters through the stationary piston and traverses the grounds, the beverage thus obtained leaves through an orifice of the counter-plunger extended rearwardly by a tube sliding in the flow conduit to leave the percolator. 8. Percolator unit according to claim 1, wherein the scraper assembly is borne by a lateral arm rotating about a horizontal pivot perpendicular to the longitudinal axis of the percolator and mounted on a movable part sliding on the secondary rails and maintained in a resting position by a spring and an abutment, the arm comprising a device, provided to tilt said arm downwardly by butting against the front plate, one of a return abutment and rack forcing the device to resume its original position during the return. 9. Percolator unit according to claim 8, wherein the front surface of the counter-plunger is cambered along the path followed by the scraper assembly during the removal of the grounds, so as to improve the efficiency of the sweeping. 10. Percolating unit according to claim 8, wherein the infusion chamber, the counter-plunger and the movable part of the scraping assembly are driven by the tie-rods due to ribs or fins thereof located on the sides of the inf usion chamber, the tie rods being pivotable one quarter turn so as to allow one of locking and release of the assembly; to this end, the bodies of the infusion chamber and of the movable part of the scraper assembly comprise passages whose form allows them to slide on the ribs or fins when the tie rods are in the unlocked position. 11. Percolator unit according to claim 10, wherein the front plate comprises holes allowing the passage of the tie rods, regardless of their position; after the sweeping phase, said tie rods extend beyond the front of the front plate to allow the user to pivot them one quarter turn due to the maneuvering ribs or fins to obtain the unlocking in order to extract the assembly for cleaning and maintenance. 12. Percolator unit according to claim 10, wherein the infusion chamber comprises, for each tie rod, double supports bearing the passages and arranged on each side of the ribs or fins such that the infusion chamber is driven in both directions by the movements of the tie rods. 13. Percolator unit according to claim 1, wherein filling the infusion chamber is done from the top due to an upper opening. 14. Percolator unit according to claim 1, wherein filling the infusion chamber is done on the sides, through lateral openings allowing to use two grinders that can be controlled individually and to output on request two distinct hot beverages. 15. Percolator unit according to claim 1, wherein the hot beverage comprises coffee. 16. Percolator unit according to claim 1 wherein the coffee is of the espresso type. 17. Percolator unit according to claim 8, wherein the device comprises a cam. 18. Percolator unit according to claim 14, wherein the two distinct hot beverages comprise at least one of regular coffee and decaffeinated coffee, or two complementary coffees at the user's request. 19.
