Sending cylinder for hydraulic clutch of vehicle, with control able to open up channel in setting remote from rear dead point

摘要

The sending cylinder has a piston (2) with a core (11) on a piston rod (3). A shell (12) can be moved along the core. The shell controls a channel (6) leading to a storage container, depending on the movement of the piston. This reliably enables negative pressure in the compression cavity (5) to be avoided.
