ABSTRACT:
A discharge apparatus (1a) has at least one slide (7a) with a bearing and/or contact surfaces (17a, 21a or 31a, 35a) engaging in pretensioned manner in at least one working position, in which for at least one of the surfaces is provided a device (20, 20'), with which it is possible to vary the compressive stress acting on the surface as a function of the control path of the slide. For example, piston lips (18a, 22a) can be relived in the rest position for reducing temperature-dependent deformation tendencies, or a valve closing stress can be increased or decreased.
