DESCRIPTION
A pneumatically driven hydraulic
pump provides continuous high
pressure oil supply to the high
pressure inlet valve. The pump
output pressure is set to the
desired level using the front
panel drive pressure regulator
and indicator. The high pressure
inlet valve admits pressure from
the pump for rough ascending
pressure control and the high
pressure exhaust valve returns
to the reservoir to decrease
pressure. The high pressure valves
are specially designed metering
valves that operate in a half-turn
and cannot be over tightened.
Fine pressure adjustment is
achieved using a piston based
variable volume. Rather than
being activated by rotational
force like a screw press, the
variable volume is pneumatically
activated through a diaphragm.
Push button momentary valves
adjust the air pressure on the
diaphragm providing both
effort free micro adjustment
and very rapid piston movement
as needed. The physical efforts
and "end of stroke" operational
problems of conventional
screw presses are completely
eliminated. The variable volume
piston position is indicated on
the front panel.
