A printing press including a device for feeding a viscous fluid, such as a lacquer or varnish. The viscous fluid, such as a lacquer or varnish, can be taken from a cartridge and be distributed to a printed sheet or other suitable medium. In the manner of a pendulum, a pipe can be mounted on a carriage by means of a pivoting bearing. Via a lever, in both pivoting directions, The pivoting bearing can be supported on compression springs and at the upper end of the pipe, there can be disposed a sealing body which corresponds to a sealing surface provided on the carriage. The lower end of the pipe can determine the height of the fluid level in the fluid reservoir so that, with the pipe being in a perpendicular position, the feed opening formed in the carriage coincides with the feed opening of the pipe such that fluid is fed, whereas the feed can be interrupted when the pipe in in an oblique position.
