OPERATION
The pump gearmotor, energized by one of the three control units,
rotates an eccentric (A) connected to a rod that drives the pump
piston (B).
On the prime stroke, the piston opens the inlet port (C), allowing
oil from the reservoir to flow into the piston chamber. On the
power stroke, the piston motion closes the inlet port and forces
the oil through the spring-loaded check valve (D) and the outlet
port (E), and into the line to the divider valves. When "On", the
pump gearmotor rotates the eccentric at a fixed speed of one
pump strokes every 5 seconds on 60 hz, or one stroke every 6
seconds on 50 hz. The piston meters a fixed .010 in
3
(0.16 cm
3
) of
oil for every pump stroke. The total volume of oil delivered to the
system is determined by the frequency and length of "ON TIME"
that the pump is operated.
