摘要： A percussive mechanism, which is provided in the form of an, e.g. pneumatic spring percussive mechanism, comprises an electrodynamic linear drive, a drive piston, which can be reciprocally moved inside a percussive mechanism housing by the linear drive, and a percussive piston. An additional hollow space is provided in front of and/or behind the drive piston and can be isolated at least in part from the surrounding area so that a pneumatic spring can be created in the additional hollow space. The pneumatic spring slows the drive piston at its returning points and facilitates a returning motion without loading the electrodynamic linear drive.

摘要： A vibrating plate for compacting soil comprises an upper mass; a lower mass, which is elastically coupled to the upper mass and which has at least one soil contact plate, and; a vibration generator device that acts upon the soil contact plate. The vibration generator device comprises at least four unbalanced masses that can each be rotationally driven about a rotation axis, the rotation axis of at least two of the unbalanced masses being arranged at an angle to the rotation axes of the other unbalanced masses. One of the unbalanced masses depicts a reference unbalanced mass that does not require its own phase adjusting device. On the other hand, a separate phase adjusting device is assigned to each of the other unbalanced masses, enabling the phase position of these unbalanced masses to be individually adjusted with regard to the reference unbalanced mass.

摘要： A vibrator for a ground compaction apparatus includes two parallel shafts which are coupled to one another be rotatable in opposite directions and on each of which is at least one unbalanced mass is disposed. A phase adjusting mechanism is used for modifying the phase angle of the two unbalanced masses relative to each other. In order to do so, the actual phase angle of the two unbalanced masses is detected with the help of proximity sensors or the like. A regulating device compares the actual phase angle with a desired phase angle that is predefined by the operator and controls the phase adjusting mechanism in such a way that the difference between the actual phase angle and the desired phase angle is minimal.

摘要： 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.

摘要： A method and apparatus for forming a stream of molten material. The apparatus includes a melt container having a bottom wall in which is formed an aperture. A funnel is adapted and constructed to receive molten material from the aperture in the container, and includes a plurality of fluid-cooled metallic segments. The funnel segments define an inner funnel contour that decreases in cross-sectional area from the inlet end to the outlet end of the funnel. An electrically conductive coil surrounds the funnel, and has a shape corresponding to the outer shape of said funnel. A source of medium-frequency current in selective electrical connection with the coil. The method begins with the step of providing a predetermined quantity of molten material in a melt container. A metallic funnel is provided in fluid communication with the melt container, and includes a plurality of fluid-cooled funnel segments. The method also includes the step of providing an electrically conductive coil surrounding the funnel. When molten material flows from the melt container through the funnel, AC current is passed through the coil at an intensity sufficient to heat the molten material flowing through the funnel.

摘要： A vibrating plate comprises a vibration generator device, which can be controlled in such a manner that the direction of the action of force can be set at a number of locations, particularly in more than two locations. In addition, an advance adjusting device is provided for controlling the vibration generator device whereby the direction of the action of force is set in a position in which a maximum possible advance of the vibrating plate is reached. The direction of the action of force can be changed according to a change in the surroundings of the vibrating plate, particularly to the slope and/or the hardness of a subsoil to be compacted by a soil contact plate. Alternatively, the direction of the action of force can be changed according to the wishes of the operator.

摘要： A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.

摘要： An implement has an internal combustion engine and a hydraulic system that can be driven by the internal combustion engine for bringing about a working movement. Furthermore, an energy accumulator is provided for the storage of energy in an accumulation phase in which the output delivered by the internal combustion engine is greater than the output currently required by the hydraulic system, and for the delivery of energy in a discharge phase in which the output delivered by the internal combustion engine is smaller than the output currently required by the hydraulic system. The energy accumulator thus serves for balancing output peaks and valleys such that the internal combustion engine may always be operated within an optimum range of rotational speeds.
