- the piston compressor is also advantageously in the Output area arranged for easy coupling of compressor and Perform valve element.
- the piston compressor transverse to Longitudinal axis of the receiving area movable, so that for example mechanical unit can be formed from the valve element and piston. This reduces the number of components, the assembly and the Maintenance effort.
- the handle is advantageously a pivotably arranged lever, the axis lying transversely to the longitudinal axis of the receiving area and swung here and with little effort through the Lever translation corresponding movements of the movable elements in the Can generate output area.
- a pressure relief valve is additionally in the output line arranged to the valve element.
- This pressure relief valve causes first by moving the handle and thus moving the A minimum pressure must be generated in the intake area before the compressor the medium that regularly passes through the valve element, also that Pressure relief valve can happen.
- a second device for Generation of a pressure deviating from normal pressure is provided with the one at the other end in the opposite direction from Normal pressure deviating pressure can be generated.
- the aspect of the invention thus boils down to the fact that when on Output area of the recording area a negative pressure is generated, an excess pressure is additionally generated at the opposite end.
- the adjustability or controllability of the pressure conditions becomes automatic causes that on the one hand the residual quantity emptying can be controlled, on the other hand, the material behavior of the inserted cartridge.
- the second Device is a piston element.
- This preferably produces one of the Atmospheric pressure deviating from normal pressure.
- the pressure generating device be a Double piston element is.
- Such a double piston element can Movement in one direction at a cylinder end a negative pressure when Move an overpressure in the other direction at the other end of the cylinder generate, for which only an appropriate cable routing is required.
- the double piston can preferably be actuated by levers, whereby a single or two movable levers can be used.
- the one from normal pressure deviating pressure is advantageously an air vacuum or a Atmospheric pressure.
- the lines can either be in the lever itself or in a side wall of the recording area.
- the line can also stand Line be arranged in the interior of the receiving area.
- Essential The function of the lines is to send the air pressure generated by the compressor to the end of the dispenser opposite the dispensing area of the dispenser To guide the recording area in order to put as much pressure on the To guide the back of the cartridge.
- the device shown in FIG. 1 is an output device 1 with a Receiving tube 2, in which a cartridge known per se (not shown) can be used.
- a discharge opening 3 is formed at one end, at the other end a lid 4 can be placed.
- a piston (not shown) 5 is inserted on the output side by means of which can be carried out via the gear 7 and the lever lifting movements are.
- a cartridge inserted into the receiving tube 2 is either open connected to the output area or, as shown Embodiment, opened by the opening device 6.
- the piston has a compression stroke and an intake stroke.
- the piston in one case on the side of the Output opening 3 a negative pressure, in the other case on the side of the Cover 4 generates an overpressure.
