A very easy-to-actuate, replaceable tool fitting is comprised in that at least one movably supported profiled body () on an output spindle () or on the tool fitting () of the hand-held power tool and at least one profiled recess () on the output spindle () or on the tool fitting () are shaped and situated in such a way that when the tool fitting () is slid onto the output spindle (), the at least one profiled body () engages in detent fashion in the at least one profiled recess (), achieving both an axial locking and a rotary driving of the tool fitting () in relation to the output spindle () and means () are provided, which, through a rotating and sliding motion of the tool fitting () on the output spindle (), guide the profiled body () into the profiled recess ().

Hand-held power tool with a replaceable tool fitting

Machine tool with a chamber for lubricating agent and a pressure equalization device for said chamber

A machine tool, in particular to a hand-operated hammer drill, having a compartment containing lubricant and a device for compensation of the pressure in the compartment in the area of a bearing of a component able to be driven so as to allow rotation. It is proposed that the bearing form at least a part of a lubricant seal of the pressure-compensation device via which a pressure in the compartment as able to be compensated.

Machine tool with a chamber for lubricant agent and a pressure equalization device for said chamber

A hand power tool has a tool holder with a base body; a drive part; at least one locking body for connecting the base body of the tool holder with the drive part; a securing body which radially fixes the at least one locking body in an engaging position; an actuating element operative for unlocking the tool holder and guiding the securing body to a position which radially releases the locking body, the base body in a locking position surrounding at least a part of the drive part.

Hand power tool

Insertable tool and tool holder for drilling and/or impacting electric

A hand drill, in particular a hammer drill has a combination tool holder provided with a first tool receptacle with clamping jaws displaceable relative to a base body and adjustable by a rotatable adjusting ring to different diameters of tool shafts, and a second separate tool receptacle for tools with a groove shaft and provided with means for at least one driving and locking as well as with a central receiving opening for the groove shaft tool, and an arresting device having a blocking slider which is arranged displaceably in the base body and non-rotatably connected with the base body in a circumferential direction, the blocking slider being movable between a first end position in which a radially inwardly directed end of the blocking slider engages in the central receiving opening and is provided with teeth such that when a groove shaft tool is inserted in the receiving opening the teeth in another end position of the blocking slider non-rotatably engage with counter teeth connected with the adjusting ring.

Hand drill, in particular hammer drill

A speed governor for fuel injection pumps of internal combustion engines in which part of an oscillation damper member, in the form of a capsule, is disposed between a drive shaft and a flyweight adjuster; two claws of a support that receives the flyweights of the centrifugal adjuster and two claws of a coupling element connected to the drive shaft. The two claws are connected to one another by way of a segmented type buffer element, all of which protrude into the capsule. The claws of the coupling element protrude into the open part of the capsule, while the claws of the support protrude into the capsule through openings in the capsule bottom. For the sake of greater strength of the capsule, the openings are embodied in closed form according to the invention.
