Operation
The squatting toilet is flushed by pressing a push button. The pneumatic push button is connected to the control
mechanism with a control hose, which transports the air pulse from the push button to control mechanism. The air
pulsestarts theflushing cycle andconnects vacuumto thewater valve anda dischargevalve.
The water valve opens and lets rinsing water into the squatting bowl through a hose nipple.After a short delay, the
vacuumactsin dischargevalvehousing andforcesthe rubberdiaphragmin dischargevalveto open,thusconnecting
thesquatting bowlto vacuumsewer.Thecontentsof bowlare forcedinto thevacuumsewer bya pressuredifference
betweenthe bowl andvacuum sewer.
The flushing cycle in the control mechanism starts the closing cycle.Athmospheric air pulse enters the discharge
valve,which closes.Aftera shortdelay, athmosphericair pulsereaches watervalve, which closesand letsa certain
level of water at the bottom in the bowl.
After the flushing cycle has stopped, the push button and system will be ready for next flush.

Description of flushing sequence
In the standby position FIG.1
Controlvalve1isclosed.Vacuuminchambers2and3isequalized
by the jets 4 and 5. Spring force 6 holds the mechanism in the
non-activatedposition.
In the just switched position FIG.2
Airpressureapplied fromthe flushbuttonto chamber7has lifted
thelever8andopenedcontrolvalve1.Atmosphericairhasentered
chamber3throughfilter9andvalve1.Theforcefromthepressure
differencebetween2and 3hasmovedthe shaft10tothe leftand
thefollowing sequenceof eventshas occured:
The inlet valve 11 has closed. Vacuum valve 12 has opened.
Vacuum is distributed via check valve 13 to discharge valve 18
and water valve 19 which will both open. Chamber 14 is also
subjectedto vacuumthrough check valve21.
This vacuum will pull lever 8 and close valve 1 and the timer
functionwill start.Chamber3 willbeevacuated throughjet 5and
the pressure difference 2-3 equalizes. At a certain level, the
counterforce from spring 6 will outweigh and the cycle will go in
theopposite direction:
Thevacuumvalve12willclose.Theairinletvalve11willopenand
atmosphericairentersdischargevalve, watervalveandchamber
14.Thedischargevalve18willcloseandsomewhatlater(because
of the jet 17), the water valve 19 closes when a suitable water
levelhas been reachedat the bottomof thebowl.
Returning to standby position FIG. 3
The whole system goes to standby position ready for another
VT-flush.
! NOTE: Diaphragm 16 has the same effective area as the air
inletvalve 11 tobalance thevacuum forces.FIG.3
!NOTE: Checkvalve13ensuresthatconnectedvalvesinactivated
positionare unaffectedby changesin thevacuum supply level.
! NOTE: If vacuum is too low or absent the
functionis delayed.Control valve1 staysopen untilchamber 14
is subject to vacuum.

Operation
The functioning of the vacuum toilet is entirely controlled by the control mechanism.
Vacuum in the sewage piping system is the actuating medium.
Descriptionof flushingsequence seedoc. 3:01025C.
Jet1 (doc.3:01025C pos 5) controls thedischarge valveopening time.
Jet 2 (see doc. 3:01025C pos 4) counters the effect of quick changes in the vacuum supply.
Jet3 (doc. 3:01025C pos 15)delays thevacuum changes inchamber 14(see doc.3:01025C). This preventsa new
flushingprocedure tostart before theprevious procedurehas stopped.

Asthe controlvalve opens,the dischargevalve housingis subjectedto vacuum,thus forcingthe closingmechanism
