A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

An aerostatic bearing and a linear compressor that includes the aerostatic bearing. In an exemplary embodiment, the aerostatic bearing includes a guide element including holes, and a body structured to move along a surface of the guide element. The holes may include a first section close to the body, of which at least one part area features a cross-sectional surface substantially constant over its entire length which is smaller towards the body than another cross-sectional surface of an area away from the body. A method for producing a hole in an element, using a laser beam, for producing the aerostatic bearing is also disclosed.

Aerostatic bearing and method for production thereof

A hand power tool () with a housing () that accommodates a turnably driveable driven shaft () on which a machining, in particular disk-shaped, replaceably clampable tool is mounted, whereby the driven shaft () is capable of being stopped by means of an axially displaceable locking pin () that extends through a through hole of the housing () and is capable of being operated from the outside, said hand power tool being made more robust and more cost-effective to produce due to the fact that the diameter-length ratio of the through hole () and the locking pin () is less than 1.8 and, in particular, equal to 1.5.

Means for preventing relative twisting between a seal ring and the parts of structure accommodating it by providing that in connection with high pressure shaft seals, the axial thrust resulting from the action of the pressure of the seal ring on its low pressure side radial face is taken up by a number of projections, the cross section of the seal ring undergoing undulating deformation as seen in the circumferential direction owing to the axial flexure of individual parts of the seal ring; it is furthermore possible to have additional projections as means for preventing twisting. As a consequence of the undulation of the entire cross section of the seal ring there will also be the useful effect of undulation of the seal interface edge, constituted by parts of this cross section, on the high pressure side.
