With these liquid atomizers * or sprayers, the non-moving disk arranged between the suction pad and the partition prevents an excessive inflow of the liquid to be atomized along the piston rod to the suction pad. A soak of the suction pad or a passage of the spray into the cylinder space of the piston pump is ruled out. A soak of the pad only takes place when the device is turned around and the valve is opened by moving the piston, with a continuous flow throttled by the small cross sections of the radial StröEiungswege flow _o is possible, it has been found that the impregnation of the Öaugpolsters can be carried out through the throttled uninterrupted flow = <. u best "the cushion from üa.u _ö absorbed Sprühaittel will then be replaced by a Another piston stroke is blown out through a v / and opening of the spray device.

According to a further feature of the invention, the lower End of the "sleeve preferably made of plastic" be conical at its end resting against the partition wall. The amount of liquid flowing through can be different Can be regulated in a way, e.g. by a certain cross-section of the hat, by arranging one or more radial hats or by the conical shape of the lower end of the sleeve or by various cone angles or by a combination of the above Middle", ·

The spray device can be designed so that they can be placed on a container or that it is itself designed as a container. The container can be circular, elliptical, or any other desired cross-sectional shape.
