The lower shoulder controls supply of oil to the airscrew cylinder, the upper shoulder serves as a
seal to preclude ingress of high-pressure oil to the centrifugal governor chamber.
Installed on the upper shoulder of the elide valve ia ball bearj-ng (16) whose inner race is pressed
to the shoulder by nut (11). The outer race contacts the short arms of weights (19).
Rotation of drive shaft (7) seta to rotation the centrifugal assembly which thrusts by the enda of the
weight short arms against the face of the ball bearing outer race and rotates the latter, whereas the inner
race of the bearing and the slide valve are kept against rotation by the centrifugal mechanism spring
disposed between the slide valve and the rack,
Rack (22) meshes with the gear of control drive shaft (20).
Control shaft (1) (Ref, Fig. 3) is made integral with a gear meshing the rack teeth,
Number of teeth Z = 12, module m = 1,
The control shaft is arranged in a side bore of the governor body. The shaft rests on end bearing
(3) with one end and on sliding bearing (7) with the other end. The sliding bearing is screwed into the body
and is locked in it by retaining ring (2), entering the slots in the body and bearing. The shaft is sealed in the
body by sealing ring (6) pressed to the bearing face by spring (4) through slip washer (5). The other end of
the spring thrusts against the shaft collar to press the shaft to end bearing (3) installed in the body.
