4.4.2 The drive engine (1) is anchored to the upper mass (3) and drives the
exciter (5). The torque is transmitted by means of a friction connection
through the centrifugal clutch (9) and the exciter V-belt (10).
4.4.3 The centrifugal clutch (9) interrupts flow of power to the exciter (5) at
low engine speeds and thus permits perfect idling of the drive engine
(1). The speed of the drive engine (1) can be infinitely varied by way of
the throttle lever (6).
4.4.4 The upper (3) and lower (4) masses are connected to each other by 4
vibration-damping shock mounts (11). This damping system prevents
the very high frequencies from being transmitted to the upper mass (3).
As a result the functionability of the drive engine (1) is retained in spite
of the high compaction performance.
4.4.5 The drive engine (1) works according to the diesel principle, is
equipped with a recoil starter, draws in combustion air through a dry
type air cleaner (12) and is air-cooled.
