An apparatus according to claim 3 , in which said piston is provided with a gasket able to close said ports upon the stroke of said piston along said chamber, the apparatus being characterized in that said gasket has a circumferential development with differentiated height so as to offer, upon a rotation of piston about the longitudinal axis of said piston itself, a different front of interaction with said ports.
5. An apparatus according to claim 3 , wherein said piston is provided with an operable knob allowing the rotation thereof relative to said chamber.
6. An apparatus according to claim 3 , wherein said piston is connected with a lever for the actuation of said pump via a connecting rod having a spherical head.
7. An apparatus according to claim 4 , wherein said piston is provided with an operable knob allowing the rotation thereof relative to said chamber.
8. An apparatus according to claim 4 , wherein said piston is connected with a lever for the actuation of said pump via a connecting rod having spherical head.
9. An apparatus according to claim 1 , wherein said apparatus includes a lid adapted to said reservoir.
10. An apparatus according to claim 1 , wherein said apparatus includes a concave-shaped lid to said reservoir.
11. A bike controlling assembly comprising:
a handlebar having a tubular body portion; and
an apparatus fixed to said handlebar for controlling brakes, said apparatus including a containment body, a reservoir disposed inside said containment body for filling a fluid of a hydraulic circuit of said apparatus, and a concave-shaped portion enclosing said reservoir and buttressing against said tubular body portion, and a pump connected with said reservoir, wherein said pump includes a piston sliding within a relevant chamber provided with one or more ports for connection to said reservoir, said piston being shaped as to close said ports upon its displacement along said chamber, wherein an idle stroke of said piston inside said chamber is adjustable by a rotation of said piston about a longitudinal axis of said piston.
12. A bike controlling assembly according to claim 11 , wherein said apparatus includes a lid to said reservoir.
13. A bike controlling assembly according to claim 11 , in which said piston is provided with a gasket able to close said ports upon the stroke of said piston along said chamber, wherein said gasket has a circumferential development with differentiated height so as to offer, upon a rotation of piston about the longitudinal axis of said piston itself, a different interactive front with said ports.
14. A bike controlling assembly according to claim 11 , wherein said piston is provided with an operable knob allowing the rotation thereof relative to said chamber.
15. A bike controlling assembly according to claim 11 , wherein said piston is connected with a lever for the actuation of said pump via a connecting rod having a spherical head.
16. A bike controlling assembly according to claim 13 , wherein said piston is provided with an operable knob allowing the rotation thereof relative to said chamber.
17. A bike controlling assembly according to claim 13 , wherein said piston is connected with a lever for the actuation of said pump via a connecting rod having spherical head. includes a concave-shaped lid adapted to said reservoir.
18. A bike controlling assembly according to claim 11 , wherein said apparatus includes a concave-shaped lid adapted to said reservoir.
19. An apparatus for controlling brakes in a bicycle, the
apparatus comprising:
a pump connected to other parts of the bicycle, the pump including a piston sliding within a relevant chamber;
a containment body attached to said pump and enclosing a reservoir for a fluid defining a hydraulic circuit of the apparatus, wherein said reservoir exhibits an open concave portion shaped complementarily to a handlebar's portion to which said body is to be fixed, and said piston is provided with one or more ports for connection to said reservoir, said piston being shaped as to close said ports upon its displacement along said chamber, the apparatus being characterized in that an idle stroke of said piston inside said chamber is adjustable by a rotation of said piston about a longitudinal axis of said piston.
20. An apparatus according to claim 19 , wherein said apparatus includes a lid adapted to said reservoir.
21. An apparatus for controlling brakes in bicycles, comprising:
a pump connected with a relevant reservoir for a fluid of a hydraulic circuit of the apparatus, wherein said reservoir is disposed inside a containment body having a defined open side, the entirety of said open side facing opposite a handlebar portion to which said body is to be fixed.
22. An apparatus according to claim 21 , comprising a concave portion shaped complementarily to the handlebar's portion to which the said body is to be fixed.
