Apparatus for controlling a hydraulic circuit for clutches
Apparatus for controlling a hydraulic circuit to be used for operating hydraulic clutches with a pump ( 8 ) connected with a relevant reservoir ( 88 ) for the fluid of the hydraulic circuit and comprising a piston ( 89 ) sliding within a relevant chamber ( 80 ) provided with one or more ports ( 83, 84 ) for connection to said reservoir ( 88 ), the said piston being so shaped as to close/open the said ports ( 83, 84 ) upon its stroke along said chamber ( 80 ), apparatus being characterized in that the idle stroke of the piston ( 89 ) within said chamber ( 80 ) is adjustable through a rotation of the same piston ( 89 ) about its longitudinal axis.
1. An apparatus for controlling a hydraulic circuit to be used for operating hydraulic clutches, said apparatus comprising:
a pump connected with a relevant reservoir for the fluid of the hydraulic circuit and including a piston sliding within a relevant chamber provided with one or more ports for connection to said reservoir, said piston being so shaped as to close/open said ports upon its stroke along said chamber, wherein the idle stroke of said piston within said chamber is adjustable through a rotation of said piston about its longitudinal axis, wherein said pump is interconnected to a clutch disk-operating piston via the hydraulic circuit.
2. The apparatus of claim 1 , wherein said piston is provided with a gasket able to close said ports upon said piston's stroke along said chamber and wherein said gasket has a circumferential development with different height so as to provide, in correspondence of a rotation of said piston about its longitudinal axis, a different front of interaction with said ports.
3. The apparatus of claim 1 , wherein said piston is provided with a maneuverable knob allowing said piston to be rotated with respect to said chamber.
4. The apparatus of claim 2 , wherein said piston is provided with a maneuverable knob allowing said piston to be rotated with respect to said chamber.
5. The apparatus of claim 1 wherein said piston is connected to a pump-controlling lever via a connecting rod having a spherical head.
6. The apparatus of claim 2 wherein said piston is connected to a pump-controlling lever via a connecting rod having a spherical head.
7. The apparatus of claim 1 wherein said reservoir is disposed fully inside a storing body.
8. The apparatus of claim 2 wherein said reservoir is disposed fully inside a storing body.
9. The apparatus of claim 1 , wherein said reservoir is disposed fully inside a storing body and exhibits a concave portion shaped complementarily with a portion of a handlebar.
10. The apparatus of claim 2 , wherein said reservoir is disposed fully inside a storing body and exhibits a concave portion shaped complementarily with a portion of a handlebar.
11. The apparatus of claim 9 , wherein said concave portion consists of a lid of said reservoir.
12. The apparatus of claim 10 , wherein said concave portion consists of a lid of said reservoir.
13. The apparatus of claim 7 , further comprising:
a semicollar having a concavity of a shape suitable for complementarily fitting the handlebar on the side opposite to said body.
14. The apparatus of claim 8 , further comprising:
a semicollar having a concavity of a shape suitable for complementarily fitting the handlebar on the side opposite to said body.
15. A hydraulic clutch operating system comprising:
a pump defined by a body, wherein said pump is interconnected via a hydraulic circuit to a clutch disk;
a chamber carved lengthwise along an axis within said body;
a reservoir provided adjacent said chamber;
a port connecting said chamber with said reservoir for providing the fluid of the hydraulic circuit; and
a piston designed to slide within said chamber along said axis, said piston shaped to open/close said port upon sliding within said chamber, wherein an idle stroke of said piston is adjusted through a rotation of said piston about said axis.
16. A system according to claim 15 , further comprising:
a gasket shaped to close said port upon said piston's stroke along said axis, wherein said gasket has an inclined circumferential end portion with different height designed to provide a different interactive front with said port in correspondence with a rotation of said piston.
17. A system according to claim 16 , wherein said piston is provided with a maneuverable knob allowing said piston to be rotated with respect to said chamber.
18. A system according to claim 15 , wherein said reservoir is disposed fully inside a storing body and exhibits a concave portion shaped complementarily with a portion of a handlebar.
19. A system according to claim 18 , wherein said concave portion consists of a lid of said reservoir.
20. A system according to claim 15 , further comprising:
a semicollar having a concavity of a shape suitable for complementarily fitting a handlebar on the side opposite to said body.
