A vibrating plate serving as a tamping device comprises an upper mass equipped with a drive and comprises at least two lower masses, which are coupled to the upper mass while being able to oscillate relative to the upper mass. Each of the lower masses comprises a soil contacting plate and at least one oscillator assigned to this soil contacting plate. The oscillators can be controlled differently so that, in addition to an advancing and compacting action, a turning moment can be executed about a vertical axis (Z).

Tamping device

The invention relates to an oil supply for an internal combustion engine, comprising an oil supply device for the supply of oil to a piston, reciprocating in a cylinder. The oil supply device is embodied such that at least at a point at which the piston is in the region of bottom dead centre, oil is introduced directly into a region below the piston, by means of the oil supply device, in particular, beneath the piston crown and within the piston skirt. The oil supply device thus comprises at least one tube element, extending into a region beneath the piston crown. The tube element terminates as close as possible to a gudgeon pin, when the piston is at bottom dead center. A targeted lubrication of the mechanically and thermally highly loaded gudgeon pin can thus be guaranteed. It is also possible by means of the oil supply to supply transfer ports of a two-stroke engine with oil, counteracting a tendency to coke up.

Oil supply for an internal combustion engine

The invention relates to a soil compacting system which comprises a travelling and steerable soil compacting device and a control device. The control device is provided with an area definition device which allows a user to establish an area to be compacted and the area boundaries. A position detecting device detects the actual position of the soil compacting device. A traveler changes the direction of travel of the soil compacting device by presetting a standard value for a travelling movement of the soil compacting device in such manner that the soil compacting device does not travel past the respective area boundary but continues its travel within the area. A path planning device may be provided for fixing a presetting for a travel way which makes sure that the soil compacting device, when keeping to the preset travel way, travels at least once completely across the area to be compacted.

System and method of the automatic compaction of soil

The invention relates to a two cycle engine comprising a lean lubrication system, whereby the lubrication oil is only applied in the area of a contact surface between a piston and a cylinder. An oil outlet is provided in or below a running surface pertaining to the cylinder for this purpose. An oil aerosol can be applied alternately, according to the position of the piston, onto the running surface of a shaft pertaining to the piston and onto the running surface of the cylinder via said oil outlet.

Two cycle engine having minimal lubrication

The invention relates to a soil compacting device comprising a motion detection device for detecting an actual value for the travelling motion of the soil compacting device. Inside a travel control device, the actual value is compared with a set value that is predetermined by the operator. When a difference between these two values is determined, the travel control device corrects the travelling motion by controlling a steering device or a drive of the soil compacting device. In another embodiment of the invention, a number of vibration plates are connected by the means of connecting elements to form a soil compacting system, which is also provided with a travel control device. The travel control device controls the individual drives in order to steer the entire soil compacting system.

Mobile soil compacting device whose direction of travel is stabilized

A tool consists of a combination engine in the form of a two-cycle engine, and a motion conversion device which is connected to said combustion engine and which is located in a housing. The housing is filled with oil for lubricating the motion conversion device. A conveying device with which the oil is conveyed from the housing to the combustion engine is provided, said combustion engine being lubricated exclusively with oil from the housing and having no separate oil supply.

Lubrication system for a tool with a combustion engine

A device for generating directed vibrations has two centrifugal weights which are independently driven at the same speed of rotation but in opposite directions. The centrifugal weights are supported on a largely stiff carrier secured by a holder to a bracket. The holder allows the carrier to move relative to the bracket. When the centrifugal weights start moving, they become synchronized within a short period of time and generate vibrations which can be used in the desired manner via the bracket.

Device for generating directed vibrations

A soil compacting device has a damping system which couples an upper mass and a lower mass together with a spring system in a vibration system. The damping properties of the damping system can be modified while the device is in operation. Therefore, when the soil compacting device passes over soils having different properties, it can constantly be adjusted in an optimal manner to the ground underneath it by acting on the vibration properties of the overall vibration system.
