Abstract
A hydraulic brake distributor for a two-wheeled vehicle has an outer body that forms an internal cavity accommodating two floating piston valve elements. The two floating piston valve elements are axially movable and mutually coupled in a telescopic manner. One of the two floating piston valve elements has an internal through-channel.
Claims12
A hydraulic brake distributor for a two-wheeled vehicle, comprising:
- an outer body, comprising
- at least one first inlet hydraulically connectable to a first brake control of the two-wheeled vehicle,
- at least one second inlet hydraulically connectable to a second brake control of the two-wheeled vehicle,
- at least one first outlet hydraulically connectable to a front brake of the two-wheeled vehicle,
- at least one second outlet hydraulically connectable to a rear brake of the two-wheeled vehicle, and
- an internal cavity extending axially and defining two opposite axial ends;
- a first floating piston valve element and a second floating piston valve element, mutually coupled in a telescopically sliding manner and axially movable in the internal cavity, wherein
- the first floating piston valve element comprises an axially extending internal through-channel and a cylindrical seat at one end thereof communicating with the axially extending internal through-channel and open towards the second floating piston valve element, and
- the second floating piston valve element comprises an end portion slidably sealingly engaged in the cylindrical seat of the first floating piston valve element and defining with the cylindrical seat an axially expandable hydraulic chamber, and a sealing gasket mounted on said end portion of the second floating piston valve element for slidably engaging the cylindrical seat in the first floating piston valve element;
- a first elastic element axially urging the first floating piston valve element towards the second floating piston valve element and away from a first axial end of the internal cavity, and a second elastic element axially urging the second floating piston valve element towards the first floating piston valve element and away from a second axial end of the internal cavity;
- a first pair of axially spaced sealing gaskets mounted on the first floating piston valve element and engaged in sliding contact against a first cylindrical section of the internal cavity;
- and
- a second pair of axially spaced sealing gaskets mounted on the second floating piston valve element and engaged in sliding contact against a second cylindrical section of the internal cavity;
- and
- two non-communicating hydraulic chambers, defined within the internal cavity:
- a first hydraulic chamber, communicating with the at least one first inlet and the at least one first outlet, and delimited by the first cylindrical section of the internal cavity and by the first floating piston valve element and communicating through said axially extending internal through-channel with the axially expandable hydraulic chamber;
- and
- a second hydraulic chamber, communicating with the at least one second inlet and the at least one second outlet, and delimited by the second cylindrical section of the internal cavity and the second floating piston valve element.
