Montering
CVMO monteres i pilotledningen fra hoved-
ventilens topdæksel til hovedventilens
afgangs-side. Se fig. 2.
Pilotventilen CVMO er forsynet med
oliedæmp-ning og skal derfor altid monteres
lodret med indstillingsspindelen opad .
CVMO monteres med pilretningen mod
kompres-soren. Pilretningen for drøvleventilen
006F0006 er i det viste system underordnet.
Indstilling
006F0003 åbnes ca. 4 omdrejninger fra lukket
stilling.
006F0006 åbnes helt. Herefter indstilles
CVMO- ventilen til at åbne ved maks. tilladeligt
sugetryk.
Indstillingen af CVMO foretages ved hjælp af
indstillingsspindelen (3).
Drejes højre om (med uret) opnås højere
sugetryk – og omvendt.

The pilot valve CVMO is equipped with an oil
dash pot and must, therefore, always be fitted
.
vertically with the regulating spindle facing up-
wards.
CVMO should be fitted with the arrow in the
direction of the compressor. The direction of
the arrow for the throttle valve 006F0006 is of
no importance in the system shown.
Setting
006F0003 is opened by rotating the regulating
spindle through approx. 4 revolutions from the
closed position.
006F0006 is opened completely. The CVMO
valve is then set to open at the maximum
permissible suction pressure.
CVMO is set by rotating the regulating spindle
(3).
Clockwise rotation increases the suction pres-
sure, and vice versa.
