| 摘要 |
The invention relates to a device (10) for depositing a flowable medium, in particular lubricating oil, onto a workpiece (16). The device (10) has a base body (13) having a duct (14a) for supplying the lubricating oil, the duct (14a) ending in a cavity (14d). The cavity (14d) is covered by a mask (15) having an opening. The opening of the mask (15) is closed by a hard metal sphere (11) which is prestressed into this closure position by a spring (12). When contact is made with a workpiece the sphere is pressed into the cavity (14d) and thereby opens up the opening in the mask (15) for the discharge of lubricating oil.
