Abstract

In a discharge device (1) for free-flowing media, an outlet valve (10) has an internal valve body (11) which can be elastically compressed by an excess pressure on the inlet side and, together with the pump parts of a discharge pump (2) which can be displaced with respect to one another, can be displaced with respect to its valve seat (13) so that, together with an associated valve body shaft (22), it forms an expulsion piston which conveys media out of a blind bore (15). As a result, a very reliable valve function and a discharge at high flow rates can be achieved with an extremely simple design. <IMAGE>
