Hydraulic section having a ventilating device
View Patent ↗A hydraulic section ( 1 ) for actuating a vehicle clutch having a master cylinder ( 3 ), a slave cylinder ( 2 ) and a hydraulic line ( 4 ) which connects both cylinders and is divided into two line sections by a ventilating device ( 5 ). The line sections of the hydraulic line which act as a siphon ( 4 a ) and a riser ( 4 b ) are guided together to said ventilating device ( 5 ), such that they are spaced apart from one another, in a chamber which is formed from at least one of these ends.
1. A hydraulic section for actuating a vehicle clutch, comprising a master cylinder, a slave cylinder, a hydraulic line which connects the master cylinder and the slave cylinder that is divided by a ventilating device into two line sections, the ventilating device including a housing defining a chamber, said line sections of the hydraulic line which act as a siphon and a riser are guided together to the chamber of the ventilating device and include ends having openings that are spaced apart from one another and an axis of each of the openings are parallel to each other and offset from each other, an uninterrupted flowpath is defined between the ends in the chamber, the openings are located at opposite axial ends of the chamber, the chamber includes an upper region defined by a radially extending wall and a circumferentially extending wall, and the upper region is positioned above both of the openings.
2. The hydraulic section as claimed in claim 1 , wherein the end of the siphon is configured as a connector to the ventilating device.
3. The hydraulic section as claimed in claim 1 , wherein the end of the line section of the hydraulic line which acts as the siphon opens with a hole laterally at a top into the chamber, and an inner wall of the end of a hole of the line section of the hydraulic line which acts as the riser forms a lower boundary of the chamber in a radial direction.
4. The hydraulic section as claimed in claim 3 , wherein the hole of the line section of the hydraulic line which acts as the riser is routed further with a length (L) in the housing and an internal diameter of the housing is widened radially at least over a region (A) of said length (L).
5. The hydraulic section as claimed in claim 4 , wherein the radial widening of the internal diameter of the housing forms the chamber in the housing in the axial direction at least over the region (A).
6. The hydraulic section as claimed in claim 1 , wherein the ventilating device is arranged in the hydraulic line at a highest point of the line section which comes from the slave cylinder.
7. The hydraulic section as claimed in claim 5 , wherein an end face of a connector which is introduced into the housing forms an axial boundary of the chamber in the housing.
8. The hydraulic section as claimed in claim 1 , wherein the hydraulic section has a plurality of the ventilating devices.
