regulating piston forward until it 
seals in port "P". This cuts off the oil 

low to the nozzle and ensures that 

the nozzle line is effectively shut off.
If the pump is overloaded, i.e. more oil 
is demanded than the gearwheel is 
able to pump under the given condi-
tions, the oil pressure falls below the 
set value because the piston of the 
regulating valve moves towards its 
closed position and partially or wholly 
cuts off the return oil via port "O".

Two pipe system

Mounting/dismounting by-pass plug

In a 2-pipe-system excess oil is 
led back direct to the oil tank. In a 
1-pipe-system the by-pass plug 
must be removed so that there is 
a free passage back to the suction 
side through the return line with the 
return port closed.

Exchange of ilter

One pipe system

Function DANFOSS RSA 95 - 125

When  the  pump  is  started  oil  is 

drawn through the suction port "S" 

via ilter "H" to the suction side of the 

gearwheel set "C". From here the 
gearwheel set pumps the oil to the 
pressure side and at the same time 
the oil becomes pressurized. The oil 
is led to cut-off and regulating valve 
"V" which opens when the set pressure 
is reached.
The pressure is controlled and kept 
constant by regulating valve "V". At 
the same time the gearwheel set 
"C" distributes the oil through nozzle 
port "P" and pump return side "R" 
via the shaft seal "F".
The quantity of oil supplied to nozzle 
port "P" is determined by the pressure 
set on regulating valve "V" and the 

nozzle/resistance in the nozzle line.

In 2-pipe-systems excess oil is led 
back to the oil tank. In 1-pipe-systems 
the by-pass plug "A" must be removed 

to  give  free  low  back  to  the  suction 

side via return line "G" with return port 
"R" closed.

When  the  pump  is  stopped,  the  

pump output drops and produces a 
drop in the oil pressure. The spring 
in the regulating valve presses the 

171 505 39 10-01

This can be remedied by

 

-

reducing the pump pressure

 

-

reducing the capacity, i.e. smaller 
nozzle or greater resistance 

 

-

changing to a pump with higher 
capacity
