One-handed blackmail

The present innovation has a; ·; - hand below actuated Grease gun to the subject as they sum, greasing construction machinery, Machine tools, vehicles, etc. is used, especially in hard-to-reach places.

The device consists of a low-pressure Sciimieriuittelbeält, which also serves as a handle for operating the press. ^{The high pressure cylinder 1 is} attached to the front of the low pressure container, the piston of which is moved by means of a two-armed lever with the four fingers of the holding hand against a spring pull or pressure. The mode of operation of such manual grease guns is known. These generally contain at least one federbelestetes check valve between the high pressure cylinder and the outlet opening of the Very iermittelsO-'undstück), but usually also just such a second valve between the low-pressure cylinder and Kockdruck ^ lin / ler ^1, which ¹ the latter valve (also under I7euerd; -uck ) the continuous refilling of the lubricant from the? ^T iederdrucksylinder · in the high-pressure cylinder allows, bringing a relief Isué connected to operate the hand press.

The embodiment shown in the drawing shows

only
a hand press with / a check valve. The innovation can also be used on the known hand presses with two valves.

The innovation, consisting of a perfection of the previously known hand presses, will be explained below with reference to the drawing explained: - '

the low-pressure cylinder gives way in its longitudinal axis is cut.

Figure 2 shows a longitudinal section through the high pressure cylinder with a subsequent section through the valve and its seat.

,., Fig. 3 shows a top view of the press of the Face, on which the lubricating mouth

piece and the connecting pipe are omitted.

The two-lip piston 2 is located in the low-pressure cylinder 1, which is under the pressure of the spring 3. This spring pressure drives the lubricant through the opening 4, according to the innovation may have a rectangular or elliptical cross-section, in the high pressure cylinder 5, from which the lubricant through Depression of the high pressure piston 6 via the check valve 7 is then driven through the pressure tube 8 into the mouthpiece 9.

The high pressure piston 6 is moved by a lever

New version of p. 4 of the description

These advantages are achieved in that the fulcrum 13 is very close to the connecting plane between the low and high pressure cylinders and that the connecting line of the fulcrums 13 and 13 forms a small angle with respect to the longitudinal axis of the piston 6.

Further improvements result from a particularly expedient form of the stop for limiting the high-pressure piston stroke. This limitation is carried out by the lever arm 11, which are cranked at 12 and thereby rest against the housing of the high-pressure cylinder 3 when the stroke of the high-pressure piston reaches the intended end position.

Finally, the innovation has the following advantage: Given the short stroke of the high-pressure piston, it is necessary that the high-pressure cylinder be filled with new lubricant at a comparatively low stroke height. However, the round holes that have been customary up to now as a connection between the low-pressure container and the high-pressure cylinder are not sufficient for this. According to the innovation, this deficiency is remedied by turning an opening 4 with a rectangular or elliptical cross-section VeX ¹ instead of a round hole. Instead of one opening 4, several can be provided at the same height.

It is emphasized again that all offered by the innovation Advantages for manual lubrication guns can be used both for designs with one and for those with two valves.
