Abstract
A hydraulic fast fitting for hydraulic pipes, including a first fitting element (1) in fluid communication with a first pipe (2), provided with a first valve (3) for opening and closing the fluid communication with the first pipe (2), and a second fitting element (5), provided with a second valve (6) for opening or closing a fluid communication with a second pipe (7), and further including a removable fast-coupling device (19) for connecting said first and second fitting elements (1, 5) and establishing a fluid communication between said first and second pipes (2, 7).
Claims10
A hydraulic fitting for hydraulic pipes, comprising:
- a first fitting element in fluid communication with a first pipe, provided with a first valve for opening and closing the fluid communication with the first pipe;
- a second fitting element provided with a second valve for opening or closing a fluid communication with a second pipe;
- a removable means for connecting said first and second fitting elements and establishing a fluid communication between said first pipe and said second pipe, wherein said first and second valves (3, 6) are normally in a closing position and pass both into the opening position in the condition of connection of said first and second fitting elements, said first and second valves comprising respective first contact surfaces, which can be superimposed precisely, and respective second contact surfaces, which can also be superimposed precisely and are mobile with respect to the first contact surfaces in order to pass between a position of closing and a position of opening of the fluid communication between said first and second pipes.
The fitting according to cl aim 1, wherein said first fitting element comprises:
- a tubular body;
- a hollow cylindrical pin, inserted in a fluid-tight way inside the body, with which it can communicate through radial holes, said pin communicating at an outer end with said first pipe, while being provided at the inner end with a first contact surface with spherical geometry;
- and
- a moving element, mobile inside the body against the thrust of a spring and slidable in a fluid-tight way on said pin for opening/closing said radial communication holes, the moving element being provided at one end with said second contact surface with plane geometry;
- and said second fitting element comprises:
- a tubular element having an internal cavity, which communicates with said second pipe and is provided at the inner end with said second contact surface designed to come into contact in use with the contact surface of the moving element;
- and
- a ball, designed to come into contact in use with the spherical surface of the pin and arranged so that said ball can move inside the cavity being kept normally in the closing position against a gasket by a thrust spring.
A bicycle or motorcycle comprising:
- a tubular frame and a hydraulic circuit provided with at least one pump body connected by means of cables to a hydraulic actuator, wherein said cables pass through holes of the frame.
