Design and function
F2 is a piston pump with spherical pistons (1) inclu-
ding piston rings (2). The pistons are working at the
angle of 40° to the shaft (3). When the shaft rotates,
the pistons move up and down in the cylinder barrel
(4), forcing the oil to pass from the inlet port to the
outlet in the end cap (5). A ring gear (6) connects the
cylinder barrel to the drive shaft, causing these to
rotate at the same speed.
A barrel support (7) with a spring presses the cylinder
barrel against the end cap. An internal connection
from the housing to the suction port eliminates a se
-
parate drain line to the tank. F2 is provided with shaft
and connection flange that fits direct to PTO´s with ZF
standard.
