Embodiment Construction

[0020] The device for dosing small quantities of liquids or pastes, which is selected as an exemplary embodiment, comprises a housing 1 in which a dosing unit is arranged. The dosing unit basically comprises a dosing rod (piston) 2 which is partially surrounded by a translation rod 3 . The translation rod 3 is acted upon by a compression spring 4 . At the end remote from the metering rod 2 there is a rotary button 5 with an indicator. A replaceable metering needle 6 is provided at the end remote from the rotary knob 5 . Furthermore, the device also includes an operating button 8 . The indicator can be provided not only on the rotary button 5 but also on the visible part of the metering lever 2 and / or on the housing 1 and / or on the rotary button 5 .

[0021] The housing 1 has a substantially pin-like shape which tapers in the region of one end thereof. The casing 1 is penetrated by a multi-stepped hole 11 along its axial centerline. Said bore 11 forms an outlet 12 at one e...

Abstract

The invention relates to a device for dosing small amounts of liquid or pasty media and media containing filling material or reactive media having a defined processing time. Said device comprises a housing which is provided with an outlet, a dosing unit which is connected to the outlet and which is arranged in the or on the housing, in addition to a reservoir, for the medium, which is connected to the dosing unit and which is arranged in the or on the housing. Said inventive device, in a preferred embodiment, comprises a housing (1) which is provided with an outlet (12) and a dosing unit, in addition to a reservoir (61) for the medium. A dosing shaft (2) is arranged in the housing (1) which is sectionally surrounded by a translation shaft (3). A guiding groove (33) is housed in the translation shaft (3) and a control button (8) is guided therein, said control button passing through the groove (17) in the housing. A circuit (92) is provided in the housing, said circuit actuating a dosing shaft (2) by inserting a motor (93) and a drive (94).

Description

technical field [0001] The invention relates to a dosing device for small quantities of liquid or pasty media as well as filled or active media with a limited processing time, which device comprises a housing with an outlet, which communicates with the outlet and is placed in the housing A dosing unit in or on the housing, and a medium storage container communicated with the dosing unit and placed in or on the housing. [0002] Quantitative delivery media are known from various fields of engineering, medicine, chemistry, etc. Here, precise dosing is generally desired. The tolerances to be met during the dosing are usually in the range of a few percent, which is ensured with relatively little technical effort when dosing larger quantities. However, when carrying out small or even extremely small amounts of dosing, the resulting problems are technically difficult to solve. The dosing of small quantities of liquid media takes place, for example, in inkjet printers. During pri...
