Functionality
<Figure1>
If the supply pressure rises the flapper (2) moves the jet (3), increasing the space between the jet (3) and the flapper (2) resulting compressed air escaping from
the upper spool (5). This in turn causes a downward movement of the spool (5). If the spool moves upward the actuator (10) is supplied with compressed air. The
increase in pressure causes the drive screw (12) to move. The movement is transferred to the cam (14), creating traction on the stroke width spring (16). The
traction of the stroke width spring (16) is compensated by the lift drive. This moves the flapper (2) into its normal position, minimising the space between the jet (3).
When the air pressure drops at the jet outlets (3) the pressure again increases at the spool (5). The spool (5) would return to its normal position and attempt to
block its position (7), which would break the compressed air supply for the drive (10). If the drive (10) adjusts the motion the positioner returns to its regular position.
