Abstract: An electric hand power-tool appliance is described and which includes a spindle, a tool mounted on the spindle, a supporting element mounted on the spindle and which is movable along the spindle on a path L, and against a force F, and in the direction of the electric hand power-tool appliance, and which increases the safety of the electric hand power-tool appliance.

Abstract: A motor driven angle grinder is described and which includes an electric motor; a transmission coupled to the electric motor and which includes a motor shaft and a tool spindle; a crown wheel in the form of a hat is provided and which forms a recess that receives the tool spindle and a bearing, and wherein the crown wheel defines toothing which surrounds the recess, and wherein the transmission housing and the angle grinder have low relative height profiles which permits the angle grinder to be used in restricted or tight space working environments.

Abstract: The invention relates to a maintenance device (1) in which the individual functional modules (3-6) are aligned in a vertical direction and the compressed air flows through them in a vertical direction.

Abstract: Device for generating a lubricant spray in a compressed air line having an air passage channel (2) in a housing (1), a regulating valve (5), in particular a proportional valve, which can change, via a control flap (14), the free cross-section of passage between the inlet (3) and the outlet (4) of the air passage channel (2) in dependence on the pressure difference, and with a lubricant supply container (7) connected to the inlet (3) of the air passage channel (2) via a filling valve (6) comprising a valve body (15) and connected to the outlet (4) via a suction line (rising pipe 8) and an oil sprayer (12), wherein the filling valve (6) closes at a pressure difference of more than approximately 1 bar, wherein the regulating valve (5) and the filling valve (6) are disposed close to one another and the control flap (14) of the regulating valve (5) and the valve body (15) of the filling valve (6) are made from a single piece of elastic material.

Abstract: The invention relates to a pulse-triggered device for supplying an apportioned minimum amount of fluid, particularly oil for lubricating pneumatic systems. A valve actuated positive-displacement member may be moved using a pulse-triggered device located inside of a positive-displacement chamber, through which the fluid is supplied from a feeding channel to a discharge channel. A valve body, separate from the positive-displacement member is subjected to spring tension and may be lifted away from a valve seat connecting the two channels.
