AND REVERSE GEAR)
Operating diagrams about pneumatic epicyclic reduction gear drive circuit
Air coming from services tank, passing through a reduction gear, is reduced to the pressure of 6.5
÷ 6.9 bars and reaches consent
valve at union I.
By pressing the clutch, operate on the gearbox lever to engage a gear (1-2-3-4-5-RG); cam (A) is moved upwards and pushes pin
(B) leftwards.
The pin abuts on piston (C) valve and by lifting it, closes the supply to union 21.
By discharging air contained into the cylinder through the vent hole (D), air will then go out of union 22 thereby keeping gearbox
piston in slow gears.
