BRAKES
Q
Partial Braking of Trailer Brake
The trailer braking pressure
Pb
(acting on surface (1)
of control spool (2)) is in equilibrium with the tractor
braking pressure
Px
(acting on piston (7)).
The brake line
B
remains separated from the
reservoir and the oil in the trailer brake is thus enclosed.
Control spool (2) is shifted to the right after the
pressures have equalized and opens bore (8) to the
reservoir through port
R
. Control spool (2) is in position
d
. Flow control valve (10) is thus switched into position
a
and has no regulating function.
As in the case of the released trailer brake, the
delivery flow
Qp
from the pump passes through port
N
and flows as
Qp
-
Qx
to the tractor hydraulic system. A
control flow
Qx
passes to the reservoir through control
spool (2).
