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.
