Abstract: A portable power tool having a housing (12) and a tool (70), in particular a cutting tool, which is arranged thereon in such a way that it can be driven in a rotary and/or oscillating manner and which can be operated as prescribed by means of a suction-air flow, in particular with a dust extractor, is made especially robust and insensitive to clogging by chips by virtue of the fact that a turbine (36) having a rotatable turbine wheel (38) and a fixed turbine casing (60) serves as drive, wherein means (101) for the frictionless discharge/ejection of dust and chips that have entered the power tool inadvertently are arranged between the turbine wheel (38) and the turbine casing (60).

Abstract: The invention relates to a hand-held electric power tool comprising at least one driven rotating part (3) that is mounted in at least one bearing (7, 13). According to the invention, the rotating part (3) is vibrationally decoupled from the bearing (7, 13).

Abstract: The invention relates to a device (10, 10?) for contactless distance measurement, especially a hand-held device which allows a distance (d) between a target object (18) and at least one reference point (20) of the device (10) to be determined by means of an emitted measuring signal (16), especially by means of a modulated measuring signal. Said device comprises at least one housing (12, 13, 56) with a first end (34) facing the object (18) to be measured and a second end (35) facing away from the object (18) to be measured, and an output unit (22, 28, 29, 31) for representing the results of measurement. The invention is characterized in that at least one subsection of the distance between the object (18) to be measured and the end (35) of the housing (12, 13, 56) facing away from the object can be associated with a plurality of measured distance values via a length meter scale (36, 38, 54) that can be represented by means of an output unit (22, 28, 29, 31).

Abstract: The invention relates to a filter bag for filtering fine particles from a gas, having a filter coating at least of a certain coating thickness, and at least one filter layer of a certain layer thickness that disposed downstream of the filter coating in the direction of the gas flow. The invention is based on the task of providing a filter bag having a low tendency to clog, thus improving the service life of the dust filter bag, particularly upon the filtering of fine dusts. The task is solved in that the coating thickness of the filter coating (1) is essentially larger than the coating thickness of the filter layer (3, 4) disposed downstream.

Abstract: A portable power tool having a turbine unit (10a, 10b) is proposed, which is intended to be driven by a suction air flow (12a; 12b), and having a gearing unit (14a; 14b; 14c) via which the turbine unit (10a, 10b) is coupled to an output unit (16a; 16b; 16c).

Abstract: The invention relates to a hand machine tool comprising a first housing shell (12, 150, 162), a second housing shell (16, 156, 168) different from the first housing shell (12, 150, 162) and being connected to the first housing shell (12, 150, 162) via a damping element (58, 60, 122, 132, 158, 170, 172), and a handle section (14, 152, 164) arranged on one of the housing shells (12, 150, 162). The invention is characterized in that the first housing shell (12, 150, 15 162) at least partially encloses the second housing shell (16, 156, 168).

Abstract: Disclosed is a hand-held power tool with a housing (12) and a tool (70)—a cutting tool, in particular—located thereon in a manner which allows it to be driven in a rotating and/or oscillating manner, it being possible to operate the tool (70) using a suction air flow, via a vacuum cleaner, in particular; the hand-held power tool is made particularly robust and safe against becoming clogged with chips by the fact that it is driven by a turbine (36) with a rotatable turbine wheel (38) and a stationary turbine housing (60); means ( ) are located between the turbine wheel (38) and the turbine housing (60) for carrying away dust and chips which accidentally enter this space.

Abstract: In a hand power tool having a housing which at least in part comprises an inner housing and an outer housing, and in which the inner housing and the outer housing are spaced apart from one another, at least one damping element is provided between the inner housing and the outer housing, so that the inner housing and the outer housing are decoupled from one another.

Abstract: An eccentric grinding hand power tool has a housing, a grinding plate unit supported on the housing and being eccentrically driven, an elastic seal that dust-tightly seals the housing with respect to the grinding plate unit, the elastic seal being held on the housing both in a form-locking, positive manner and in a force-transmitting, non positive manner without separate elements but with integrated securing elements.

Abstract: In a power grinder (1) with a motor (6) and a gear (7) that drive an oscillating drive means (2), which moves a grinding belt (3) secured to it to reciprocate, a simple change of the grinding belt (3) is made possible by providing that the grinding belt (3) has a hook-and-loop closure (4), or the grinding belt (3) is disposed with its first end (11) on the drive means (2), and its second end (12) is connected to a handle (13).

Abstract: A motor-driven manual grinder (10), in particular an eccentric-plate grinder, has a work spindle (13) supported in the tool housing (11) and also has a grinding plate unit (15) that is driven and rotatable by the work spindle to execute an eccentric motion. The manual grinder (10) further has an annular first rolling face (28), extending together with the grinding plate unit (15) all the way around the eccentric axis (19), and an annular second rolling face (30), associated with the first, whose center axis extends coaxially to the central axis (17) of the work spindle (13), and on which the first rolling face (28) can roll. The second rolling face (30) is supported rotatably about its center axis. It is assigned a braking device (35), by means of which a rotation of the second rolling face (30) about its center axis can be selectively prevented for the forced-drive mode or enabled for the free-wheeling mode.
