Abstract: The present invention relates to a vibration tamper, comprising a superstructure having a driving engine mounted on a machine frame and further having a guide bar, and further comprising a substructure having a compactor base driven by the driving engine and having a compactor plate and having a drive line, by means of which a drive connection between the driving engine and the compactor base is established such that the compactor base can move relatively to the superstructure along a compactor axis while executing at least one compacting amplitude. The driving engine of the vibration tamper is a liquid gas powered driving engine, wherein the superstructure and, more particularly, the guide bar on the superstructure, comprises a storage container for liquid gas, and wherein a gas supply line is provided to supply evaporated liquid gas to the driving engine.

Abstract: A hand-guided ground compacting machine, such as, in particular, a vibration tamper, a vibratory roller or a vibratory plate, comprising a driving engine mounted on a machine frame, a ground compaction device driven by the driving engine, and a guide bar. Features of the present invention reside in that the driving engine is a liquid gas powered driving engine and that the ground compacting machine comprises at least one storage container for liquid gas which is replaceably disposed in a storage container holding means on the hand-guided ground compacting machine.
