Abstract (en)

The automatic valve consists of a stem and a conical head inside a hole through the supporting cylinder (10) or compensating sleeve (22). The valve is spring-loaded and fitted between a threaded retaining ring (38) and a similar ring with the valve seat (34). The valve seat has a conical surface matching that of the head to ensure a seal when the valve is closed. The valve is opened by pressure on its projecting tip when a printing sleeve is fitted over the compensating sleeve.
