Abstract
A hydraulic actuation apparatus for a motor vehicle clutch includes a master cylinder, a slave cylinder, a hydraulic line forming a main fluid channel connecting the master cylinder to the slave cylinder to form a pressure space, and a damping member arranged in the pressure space for attenuating pressure pulses. The damping member includes a connection channel connected to the main fluid channel and a fluid guide directing fluid from the main fluid channel into the connection channel. The damping member or other hydraulic operating component is preferably formed integrally with the hydraulic line, and is preferably injection molded plastic.
Claims23
A hydraulic actuation apparatus for a motor vehicle clutch, the apparatus comprising:
- a master cylinder;
- a slave cylinder;
- a hydraulic line connecting the master cylinder to the slave cylinder and together with the cylinders forming a pressure space;
- and
- a damping member arranged in the pressure space for attenuating pressure pulses, the damping member being assembled to the hydraulic line by a non-releasable connection and forming a single permanently integral piece together with the hydraulic line such that the master cylinder is connected to the slave cylinder by the hydraulic line and the damping member using only two coupling areas to complete the connection.
A hydraulic actuation apparatus for a motor vehicle clutch, the apparatus comprising:
- a master cylinder;
- a slave cylinder;
- a hydraulic line connecting the master cylinder to the slave cylinder and together with the cylinders forming a pressure space;
- and
- a damping member arranged in the pressure space for attenuating pressure pulses, the damping member being constructed integrally with the hydraulic line and comprising a plastic housing which is injection molded on the hydraulic line such that the master cylinder is connected to the slave cylinder by the hydraulic line and the damping member using only two coupling areas to complete the connection.
A hydraulic actuation apparatus for a motor vehicle clutch, the apparatus comprising:
- a master cylinder;
- a slave cylinder;
- a main fluid channel connecting the master cylinder to the slave cylinder and together with said cylinders forming a pressure space;
- and
- a damping member arranged in said pressure space for attenuating pressure pulses, said damping member comprising a connection channel connected to the main fluid channel and a fluid guide directing fluid from the main fluid channel into the connection channel,
- wherein the fluid guide comprises a baffle extending from the connection channel into the main fluid channel.
A connection piece for hydraulically connecting a master cylinder and a slave cylinder, the connection piece including a hydraulic line and at least one additional hydraulic operating component assembled to the hydraulic line by a non-releasable connection and forming a single permanently integral combination piece together with the hydraulic line such that the connection piece is configured to connect the master cylinder to the slave cylinder by the hydraulic line and the hydraulic operating component using only two coupling areas to complete the connection.
