ASSEMBLY CONSISTING OF AN ENGINE CYLINDER VALVE AND OF AN ACTUATOR WITH CLEARANCE COMPENSATING END STOP

摘要

Assembly consisting of an internal combustion engine cylinder valve (4) returned to a closed position against a seat (7) by a spring (16) positioned around a valve stem (3), and of an actuator (14) for returning the valve (4) to the open position comprising an actuator rod (8) designed to collaborate with the valve stem (3). Between the valve stem (3) and the actuator rod (8) there is a variable-length self-adjusting end stop (17; 27) designed to fill the clearance gap between the stem and the rod (3, 8).
