Actuator unit for push cam systems with actuator pins controlled by control needles

摘要

The combustion engine has a pneumatic stapler that is spring-loaded in direction of a sliding cam unit. A sliding cam positioning unit is secured at a remote retracted position by using a locking unit. Several clamping elements are operatively connected to spring-loaded control needles (1) by using a solenoid assembly. Several permanent magnets are detachably attached with respect to control needless. The amount of acceleration of pneumatic stapler is equal to that of spring force per unit acceleration of needles associated with the springs.
