HYDRAULIC BICYCLE SYSTEM

摘要

A normally closed port valve seals a hydraulic hose connection port of a hydraulic bicycle component. Connection of an end of a hydraulic hose assembly to the port opens the valve, placing the assembly's hydraulic fluid chamber in fluid communication with the interior of the hose assembly. A hydraulic cylinder of the assembly is in fluid communication with the chamber. A spring may be used to bias the valve to a closed condition and simultaneously to bias a brake actuating piston to a non-actuated position.

主权项

1. A hydraulic hose assembly for a hydraulic bicycle component having a hydraulic hose connection port and a port valve assembly in fluid communication with the hydraulic hose connection port, the hydraulic hose assembly comprising:
a hose having a bore; a hose end member including a stem portion disposed in the hose bore and a head portion extending beyond an end of the hose, the head portion having a contact surface for contacting the port valve assembly of the hydraulic bicycle component; and a hose sealing member sealingly engaging the hose and the hose end member, the head portion of the hose end member configured to inhibit the hose sealing member from deformably displacing beyond the contact surface of the head portion when the hydraulic hose assembly is connected to the hydraulic hose connection port of the hydraulic bicycle component.
