Function:
The clutch master cylinder (7) is connected to the brake fluid reservoir via a hose and is supplied with brake fluid via the feed (arrow A). The piston (7a) is actuated by the thrust rod (6f) and moved to the left to close the replenishing port (7c).
The pressure in the cylinder chamber increases. This increase in pressure is transferred via the pressure fitting (arrow B) to the central clutch operator with integrated clutch slave cylinder. The primary cup (7f) and secondary cup (7g) provide a seal for the piston (7a).
