An arrangement for imposing pressure on cleaning media and/or lubricants which are contained as maintenance media in the movable components of medical, particularly dental handpieces, wherein the maintenance medium is adapted to be placed under pressure by a pressure drive acting through an outlet opening of a housing which contains a motion drive for the movable handpiece components, the last mentioned being brought into connection with the outlet opening through an inlet opening in the handpiece. During this pressurization of the maintenance medium, the movable components of the handpiece are placeable into movement through the motion drive of the housing in such a manner, whereby engaging means of the motion drive which are accessible through the outlet opening of the housing can be brought into engagement with cooperating engaging means of the movable components of the handpiece which are accessible through the inlet opening. With respect to the engaging means of the motion drive, handpieces or handpiece components, in particular attachment heads, having different cooperating engaging means, can be attached to the outlet opening of the housing and maintained, and thereby place their movable components into motion. As a result of the arrangement a plurality of different engaging means for the motion drive, in a simple manner there can always be selected and placed in operation engaging means correlated with the cooperating means of the handpiece or handpiece component which is to be currently serviced.

Arrangement for imposing pressure on maintenance media in medical

An arrangement for the dispensing of cleaning and/or lubricating media, which can be placed under pressure in a receptacle, as maintenance media to movable elements containing medical, and particularly dental handpieces. The maintenance medium is forced by means of a pressure drive out of a dispensing orifice of the receptacle through an inlet opening of the handpiece which is attached to the receptacle at the dispensing orifice and whereby, during the forcing of the maintenance medium into the movable elements of the handpiece, they are placeable into motion through a motion drive. The maintenance medium can be formed by liquid cleaning and/or lubricating media, for instance, such as oil. The arrangement of a separate power source, for the motion drive and for the pressure drive, in a simple and economical manner facilitates the motion drive as well as the pressure drive to be supplied with the required energy in a completely targeted manner by the current power source for a secure operation, so that neither the forcing out of the maintenance medium nor the action of the motion drive on the movable components of the handpiece are adversely influenced in any manner or could even be inhibited.
