3. Valve Block Group
The valve block group consists of valve
block (312), valve plate (313) and valve
plate pin (885). The valve plate has two
melon-shaped ports, that are mated to the
valve block. These feed and collect oil to
and from the cylinder block.
The oil changed over by the valve plate is
connected to an external pipeline by way
of valve block.
When the drive shaft is driven by the prime
mover (engine), it rotates the cylinder
block via a splined coupling. If the swash
plate is tilted as in Figure 2, the pistons
arranged in the cylinder block make a
reciprocating motion with respect to the
cylinder block, while they revolve with the
cylinder block. If you pay attention to a
single piston, it performs a motion away
from the valve plate (oil sucking process)
within 180 degrees, and makes a motion
towards the valve plate (or oil discharging
process) in the rest of 180 degrees. When
the swash plate has no tilt angle (zero
degrees), the piston does not stroke and
neither discharges or draws oil.
