  • the capsule 300 contains a rotating drum 301, which, activated by the injection pump 100, through a pin 302, turns the hub 4 and the rear wheel.
  • All the injection pump plant 100 is supported by a circular steel plate 5 in a moulded block together with three blind sleeves 6 in which there are inserted the seat tube 7 and down tube 8 of the frame and the tube from which the bicycle fork departs (figures 2 and 3).

  • This made in sheet steel of a thickness of 2.5 millimetres or more (it must support the extremities of the axle 9 of the pedal crank 10 and the weight of the cyclist), is formed by two cases 2.12, 2.2 with drawings which are screwed into the central plate 5, already described in detail.

Between the pins 101, 102 and the small wheels 103, 104 there are placed needle bearings 107. Small wheel 103 (major planet wheel) supplies the push action and forces the crown 106 to move.

  • the radial internal wall of the solid crown 106 has a spherical notch where there run the margins suitably adapted of the small wheels or planet wheels 103, 104 and the sliding block 108.

  • the injector pistons 110 are moved by the aforementioned cams 105.
  • Each cam 105 has along its external circumference of the crown 106 a needle bearing 109 inserted in a shallow notch exploiting thermal contrast (the measurements of the cam 105 should take into account the diameter of the needles, which can be 1.2 mm, stopped by a specific cage).
  • the injectors are in ten couples for each of the two pumps (indicated in figure 22 with letters A to L) and are placed on lines radial to the axle 9 of the pedal crank 10.

  • the injection jackets 111 are in wrought iron with chroming of the surface friction strata.
  • each of the two injection pumps 100 the return of the injector pistons 110 is carried out by two return rings 113 in cemented steel of circular section which play in the specific arcuate notches 114 hollowed out in the injector pistons 110 and in the specific notches-grooves 115 hollowed out at the base of the jackets 111 (figures 12 and 21).
  • each injector piston 110 there is made an arched notch 114 in which there is lodged the ring 113. So that the insertion of the latter does not weaken to a great extent the base, in the injector piston 110 a groove is made, whose extremity is the arcuate notch 114.
  • Each of the injection jackets 111 has at its base two notches 115 counterposed in the walls and at a height such as to permit the easy movement of the return ring 113 to their interior.
  • Each injection jacket 111 has an appendage 118 in which the suction valve is open. The oil flows in this appendage 118 before passing into the port of the injection jacket 111 through an elliptical opening 119.
  • the valves of suction 120 and of injection 121 of the pump 100 are placed at the head of the coupled injection jackets 111. They are made in a single block with their pin 122.
  • these valves of suction 120 and injection 121 consist in metal plates connected via arms 123 to the central pin 122.
  • the four valves 120, 121 in block exchange the thrust and thus accelerate the closure of the suction valves 120 thus avoiding substantial losses in the volume of the pressurised oil. In this way the suction valves 120 also open faster - by no means a not a negligible factor.
  • the ports 124 of the suction valves 120 consist in holes made in a plate 125 while the ports 126 of the injection valves 121 consist in holes made in another plate 127.

  • the port 124 of the suction valves 120 has a greater surface, more than three times that of the port 126 of the injection valve 121. It is necessary that the port 124 is of this size to avoid the formation of empty pockets inside the injection jacket 111.
  • Each couple of twin injectors is cast with a support 112 of anchorage which is fixed to the central plate 5. These supports 112 are highlighted in figures 18 and 19. The support of anchorage 112 is in part cut by one of the notches 115 which permits the clearance of the return rings 113 of the injector pistons 110.
  • a semi-cylindrical notch 129 is present between the appendages 118 where are located the suction valve 120 of the twin injection jackets 111 and it attends to the placement of the pin 122 of the suction valves 120 and injection valves 121.
  • the plate 127 where the injection valves 121 are located also has a semi-cylindrical notch 132 made in the part which will be external to the injection jackets 111 to accommodate the pin 122.
  • This plate 125 will also have a semi-cylindrical notch made in the marginal parts of the manifold 128 and in the part underneath for the whole length of the pin 122.
  • This semi-cylindrical notch which is marked with a broken line in figure 16, will complete the cylindrical container area of the pin 122 of the valves 120, 121.
  • the precise alternating of the action of the pistons guarantees the perfect synchrony of the valves 120, 121 which, being in a block, exchange the thrusts of opening and closing.
  • the travel stroke of the injector pistons 110 in the injection jackets 111 is placed on radial lines which depart from the centre of the axle 9 of the pedal crank 10 which is also the centre of rotation of the cams 105.
  • Each cam 105 as an effect of the pedalling, moves in the same direction as the bicycle and the position of the same cam 105 determines the active phase of the injectors (as illustrated in figure 22) marked B, C, D, E and the passive phase, of suction of the injectors marked G, H, I, L while the injectors marked A, F, are in the exchange phase.
  • the position (illustrated in figure 23) of the injector D, position with respect to the cam 105 in which all the injectors will find themselves, is critical; the real direction of the thrust of the cam 105 on the basis of the injector piston 110 has an accentuated angling respect to the stroke of piston 110 in its jacket 111.
  • FIG 23 which illustrates an injector - broken line - in position D
  • the direction of rotation of the cam 105 is indicated by the curved arrow;
  • the long arrow which departs from the centre of the cam, indicates the real direction of the thrust of the cam 105 definitely outside the travel stroke of piston 110 indicated by the short arrow and placed on a radial line.
  • the jacket 111 and the piston 110 which in figure 22 occupy the position D, are marked in a broken line; a full line marks the jacket 111 and the piston 110 with angle corrected in a contrary direction to the movement of cam 105.
  • the vertex of the angle to measure is placed at the centre of the circumference of the external margin of jacket 111.
  • the angling cannot be accentuated too much because this would jeopardise in particular, the injectors which would come to be in position H, I in figure 22.
  • the oil under the thrust of the injector pistons 110, crosses the injection valves 121 lodged in the plate 127 where there are the same injection valves 121 and from the manifold 128 of the twin injectors, passes in the circular manifold 133 joined by means of nuts 134 which connect ten couples of injectors placed in star around the axle 9 of the pedal crank 10.
  • a connection between the circular manifolds of the two injection pumps 100, in the two compartments adjacent to box 2, placed at height of the lower right element 16 of the fork of the rear wheel, will comprise the initial part of a tube 17 (figure 31) which will leave casing 2 and will terminate in the support 303. From the latter to capsule 300 a flexible tube 18 will take the oil to manifold 304 of the injection ports 305 of the capsule 300 placed near the hub of the rear wheel (figures 1 and 31). Within capsule 300 (figures 24 and 25) is placed a rotating drum 301 of a smaller diameter than the circumference of the space of the body 306 of the capsule 300.
  • the peripheral surface of the drum 301 touches the edge of the internal wall of the body 306 of the capsule 300 thus creating a space which varies, between the body 306 and the drum 301.
