Abstract

A hydraulic line coupling, for a hydraulic brake or clutch of handlebar-operated vehicles, having a line connection piece with a hydraulic line extension and a housing with a coupling opening, in which the line connection piece for coupling the line to the housing can be disposed. The connection piece comprises a passage connected to the line. A valve device is disposed in the housing and is configured such that the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. The line coupling has a seal, with which seal the valve device closes the connection for the connection piece when the connection piece is not in the coupling opening. With the seal, the connection piece seals the passage from the environment when the connection piece is in the coupling opening.

Dependent claims

A hydraulic line coupling for a hydraulic brake or clutch of vehicles having handlebar steering and a hydraulic line, the hydraulic line coupling comprising:

first and second line connection pieces separate from one another, each of the line connection pieces comprising an extension shaped to connect to the hydraulic line and defining a passage to be connected to the hydraulic line;
a housing:
defining first and second coupling openings in which a respective one of the first and second line connection pieces is to be disposed for coupling the hydraulic line to the housing;
and
defining therein an interior compartment communicating with and disposed between the first and second coupling openings;
a pressure chamber housing:
disposed in the interior compartment;
and
defining therein a pressure chamber;
a valve device disposed in the pressure chamber of the pressure chamber housing and configured to close the first coupling opening when the first line connection piece is not in the first coupling opening;
first and second seals:
with which the valve device closes the first coupling opening when the first line connection piece is not in the first coupling opening;
with which first seal the first line connection piece seals the passage from the environment responsive to the first line connection piece being in the first coupling opening;
and
together with an interior surface of the pressure chamber housing, fluidically sealing off the pressure chamber housing from the environment to, thereby, pressure-tightly connect the passage of the first and second line connection pieces to one another through the pressure chamber responsive to the first and second line connection pieces being in a respective one of the first and second coupling openings, the first and second seals each disposed and formed to seal, in a radial direction, between:
the pressure chamber housing;
and
a respective one of the first and second line connection pieces inserted into a respective one of the first and second coupling openings.
