The 110 actuator is consisting of two opposed in line cylinders inside which move two pistons integral with a rack. The rack drives a quadrant which is partly housed within the volume enclosed by the cylinders.
This construction principle which eliminates the need for a linkage rod from the piston, has the following advantages :
There are several models of this type of actuator. Each is defined by a reference number with four groups :
For exemple :
Double-acting SERVO-MOTOR comprising two rnoving cylinders. The two pistons are solidly connected by a rack, the tooth reaction is taken on needle sliders.
Body of semi-steel, cylinder of aluminium alloy, cast iron or steel, seals and gaskets of neoprene or elastomer, quadrant and rack in half-hard Martin steel. The main drive shaft is of lnoxyda bronze or chrome steel, the guide being of bronze. Ali external linkage elements are hard chromium plated or cadmium plated. External protection is baked enamel or phosphate paint. Operation is not affected by the position of the actuator (but this should be specified with the order). Operating medium inlet 1/4" BSP.
