ADJUSTABLE DEVICE FOR VALVE CONTROL AND METHOD FOR ADJUSTING SAME

摘要

The invention concerns a valve controlling device with linear displacement along an axis comprising a number of actuators equal to that of the valves. Each actuator has a ferromagnetic blade fixed to a valve push rod and at least a return spring whereof one end is supported against the rod and the other end is supported against fixed anchoring means, adjustable in position relative to a housing of the actuator. A passage is provided between the actuators of the two adjacent valves to allow through an adjusting tool.
