2.2 Description of function
2.2.1 The exciter (2), which is integrated to the lower mass (1), produces the
vibrations required and centrifugal force for the compaction process.
This exciter is of the single directional type and has been designed to
create circular vibrations.
2.2.2 The engine (4) drives the exciter (2) and is fixed to the motor console
(3). The engine torque is transmitted via the centrifugal clutch (5) and
the exciter V-belt (6).
2.2.3 The centrifugal clutch (5) interrupts the power flow to the exciter (2)
when the engine is turning at low rpm’s, thereby allowing a flawless
idling of the drive engine (4). The drive engine’s (4) rpm can be
changed from full to idle and stop by way of the throttle lever (7).
2.2.4 The engine console (3) and the lower mass (1) have be connected to
each other by means of 4 vibration absorbing shock-mounts (8). The
damping effect reduces the transmission of the very high frequencies
to the engine console (3). With that, and despite the high compaction
efficiency, the functionality of the drive engine (4) is maintained.
2.2.5 The drive engine (4) works according to the diesel principle, is
equipped with a recoil starter, draws in combustion air through a dry
type air cleaner and is air-cooled.
