Figure 7-30 shows two views of a manifold. This
manifold joins both the pressure and suction lines
from the No. 1 system pumps and the suction line
from the emergency system pump. The assembly
includes integral check valves to direct the flow of
fluid through the manifold, filters to clean the fluid
prior to its entry into the main system, and
quick-disconnect fittings for the connection of ground
test hydraulic equipment.
FILTERS
Hydraulic fluid will hold in suspension tiny
particles generated during normal wear of selector
valves, pumps, and other system components. These
minute particles may damage or impair the function
of the units and parts through which they pass if they
are not removed by a filter. Because close tolerances
exist within a hydraulic system, the performance and
