A hand-held power tool, in particular a hammer drill, includes a tool holder and a housing which has two housing half-shells. The hand-held power tool further includes a drive unit for driving a tool holder arranged in the housing. The drive unit includes at least one drive motor arranged in a motor support and a gear unit arranged in a gear unit housing. The motor support is connected directly to at least one of the two housing half-shells via at least one non-positive connection and at least one positive-locking connection. A relevant fastening axis is assigned to the at least one non-positive connection and to the at least one positive-locking connection. The fastening axis is arranged at right angles to and at a distance from an axis of rotation assigned to the tool holder.

A device for degassing and/or dehydrating a hydraulic oil includes a flow lance, a flow duct, and a decoupling module. The flow lance includes a restriction site via which the hydraulic oil flows under a high pressure drop. The flow duct is configured as a pipe that is located downstream of the restriction site. The quantity of oil that flows via the restriction site and a throughflow cross section of the restriction site are coordinated to one another such that a cavitation zone or supercavitation zone forms downstream of the restriction site. The flow duct has a significantly larger cross section with respect to the throughflow cross section of the restriction site. For a quiet operation of the device, the flow lance is held in the decoupling module via which the flow lance is configured to be fastened in a vibration-decoupled manner to a tank.

A dust extraction device for a hand-held power tool includes a housing, a mechanical interface for releasably connecting the dust extraction device to the hand-held power tool, a dust-collecting chamber which is connected to a filter unit, and a filter-cleaning unit. The filter-cleaning unit has an impact element which is mounted moveably in and/or on the housing of the dust extraction device. The impact element is designed to act upon the filter unit directly with an impact-like force.

Vacuum cleaning device

A hydraulic unit includes an assembly with a hydrostatic positive displacement pump and an electric motor. The positive displacement pump includes a driving shaft configured to be driven by the electric motor. The hydraulic unit also includes an inert mass on which the assembly is rigidly mounted so as to minimize vibration of the assembly and reduce noise emission from the assembly.

Hydraulic unit

A hydraulic unit includes a tank configured to be filled with a hydraulic fluid. The tank has at least one inflow connection and at least one outflow connection. A flow guide for the hydraulic fluid is formed between the inflow connection and the outflow connection. The flow guide is configured to have at least two 180&#xb0; flow arcs configured to cool and calm the hydraulic fluid and to avoid dead zones.

Tank for a hydraulic unit

A tank has an annular tank space, and a separating wall for separating an inflow connection from a drain connection is provided therein. Alternatively, or in addition thereto, a partition for degassing the oil in the tank is provided. Furthermore, alternatively or in addition thereto, at least one partition for extending a flow path of the oil is provided. It is also conceivable, alternatively or in addition thereto, to arrange a cooling device in the annular space.

Tank, and electrohydraulic compact assembly having a tank

A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

Hydraulic system

A hydraulic unit having a housing includes a tank and a pump arranged adjacent to one another in a fluid supply region, and a controller region is arranged thereabove. Since the pump is embodied in an upright design, a compact hydraulic unit with a small footprint is implemented.

A baseplate has a top side that includes a support surface and a collecting surface. A hydraulic appliance is configured to be fastened on the support surface. The collecting surface is arranged lower in relation to the support surface so as to collect leakage oil of the appliance.

A micromechanical device having a substrate wafer, a functional layer situated above it which has a mobile micromechanical structure, and a cap situated on top thereof, having a first cavity, which is formed at least by the substrate wafer and the cap and which includes the micromechanical structure. The micromechanical device has a fixed part and a mobile part, which are movably connected to each other with at least one spring element, and the first cavity is situated in the mobile part. Also described is a method for producing the micromechanical device.

In one embodiment, a sensor includes a rigid wafer outer body. A first cavity is located within the rigid wafer outer body, and a first vibration isolating spring is supported by the rigid wafer outer body and extends into the first cavity. A second vibration isolating spring is supported by the rigid wafer outer body and extends into the first cavity, and a first sensor packaging is supported by the first vibration isolating spring and the second vibration isolating spring within the first cavity.

Robust inertial sensors

A safety device for vehicles having first sensor arrangement for acquiring the vehicle impact and for outputting first sensor signals, a control device for outputting triggering signals dependent on the first sensor signals, and a restraint system that is triggered dependent on the first sensor signals, second sensor arrangement being provided for the acquisition of obstacles in the vicinity of the vehicle and for the outputting of second sensor signals, and third sensor arrangement being provided for the acquisition of environmental influences on the second sensor arrangement, the second sensor signals output by the second sensor arrangement being used in the control unit for the decision concerning the triggering of the restraint system, after an evaluation of the third sensor signals output by the third sensor arrangement.

An apparatus for triggering restraint devices includes crash sensors inside and outside of a control unit. The apparatus checks a crash signal of the crash sensors using a plausibility signal. To check the crash signal, the apparatus receives the plausibility signal from a vehicle sensor outside of the control unit, and then triggers the restraint devices as a function of the crash signal and the first plausibility signal.

Apparatus for triggering restraint devices

A method for processing sensor data which are transmitted by at least one asynchronous sensor at a transfer rate into a buffer memory, the sensor data being read from the buffer memory at a predefined sampling rate, and a mean value being computed from a predefined number of read sensor data. The transfer rate to sampling rate ratio is selected in such a way that the number of sensor data averaged within a sampling period is n or (n+1), the mean values of the read sensor data being computed using a fixed synchronized phase shift with respect to the sampling rate, which is determined in averaging (n+1) sensor data, n being a natural number greater than or equal to two.
