4.3 Functioning
A pneumatically unilaterally operated
piston delivers the oil into the delivery
pipe. Due to the spring power the piston
is reset in order to suck the oil from the
reservoir in. During the suction process
the delivery pipe’s pressure will be de-
creased down to approx. 0,8 bar. The
integrated pressure control valve opens
at 32 bar.
Attention!
When air pressure is impinged suddenly, the pressure control
valve’s start-to-leak pressure may be exceeded and that pressure
will not build up in the outlet then. As a result, the delivery capac-
ity will decrease.
Adjustment of the volume flow:
The volume flow can be variably adjusted (option). To do this, turn the adjustment screw to
the right, until the desired volume flow is reached. Each revolution of the adjustment screw
reduces the volume flow rate by 0,4 cm³.
The PEK is preset to the max. volume flow when delivered.
