CHAPTER 3: INSTRUCTIONS 3-5
SUPER HYDROBAR HS
Internal valve of piston
The internal valve of the piston serves to calibrate the quantity of oil that passes from the compression
chamber (behind the piston) to the guide tube in which the bar turns.
This valve is set in the factory but if, for any reason, the setting has to be adjusted, please proceed as
follows:
(this setting can be checked only when the bar-feeder is operational).
Regulative the valve:
The quantity of oil that passes through the valve is adjustable by means of the regulating screw (A).
A)
Tube in feeding position (swung back)
B) Pusher blocked so that the piston is at least 200 mm shy of the stop ring.
C) Thrust-pressure set (see point 2.2.4.).
D) Flow regulated (see point 2.2.4.).
E) A1 selector on AUT
F) Lath and SUPER HYDROBAR HS ON.
A thread of oil, the size of a finger, should flow out into the collector. If that is not the case, the pusher will
have to be extracted from the tube again (as indicated in point 3.1.3.), then :

If the thread of oil is too thick, it is necessary to tighten the screw (A) on the piston valve (B).

If on the contrary the thread is too thin, release the screw (A).
Pistons of less than 10 mm in diameter, have no interior valve. Calibration is done by
taking the difference between the external diameter of the piston and the internal
diameter of the tube. That difference should be 0.3 - 0.5mm.
When the control is in position R, the direction of rotation of the pump is reversed and
the oil which is in the guide tube is sucked in. At this point, the ball (D) is pressed up
against the ring (C) and acts as a valve. The pusher withdraws.
