Abstract

The appliance has a cylinder housing (1) which is provided with a flange (2) and whose temperature can be regulated, with a piston unit, designed as a delivery and dosing member, having a main piston (9) and a valve piston (10) attached thereon. In order to be able to dose, in an accurate and trouble-free manner, even highly viscous media and even, if required, from storage vessels under vacuum, an inlet port (4) interacts with the valve piston (10). A dosing chamber (5) whose diameter is greater than that of the inlet port, has an outlet port (6) leading therefrom, which debouches into a non-return valve (7) which is closed against the dosing chamber. The main piston at its underside has a drive rod (12) which is provided with adjustable end stops (11).
