Pneumatic vibrator

The invention relates to a pneumatic vibrator with unbalanced mass acted upon by compressed air.

Vibrators are already known, a stationary axis being arranged coaxially with the cylindrical housing and the rolling element is designed as a cylindrical hollow roller pushed onto this shaft, and wherein the inside diameter of the hollow roller is larger than the diameter of the fixed axle, and the outside diameter the hollow roller to its inner diameter so it is to be added that the outer cylindrical surface of the roller can never touch the inner wall of the housing.

Furthermore, designs are known in which the roller body is arranged on and from one another within the stator separate roller tracks is stored on which it rolls. Stand and rolling body are in their dimensions matched to one another in such a way that constantly between the roller body and the cylindrical inner wall a narrow air gap remains.

A well-known version uses a vibrator, in which the movable cylinder sin © the center of gravity of its circular cross-section Iu in relation to its geometrical

BATH ORIGINAL

gates from · a lot of individual parts suaaaaan, the manufacture and processing of which is «rather time-consuming» waa eloh In elnea vorblUtiiiasjIllg hone free of tanning auedrUoJrt. The career paths, especially with the ball vibrators, are tied in a Xrelefom, there eloh with other designed runway the airflow from the The train lifted off * so that the dleee places could not work. In these well-known places duroh i.B. a rolling ball is a pure kinetic one Energy generated. A simple interaction of small energy and potential energy, dealt “In the performance increase of the AroeltegerKUe is not possible.

The object of the invention is therefore to verify the laohtelle occurring in the known places and to develop a vibrator which can be manufactured most economically using the simplest means and auglelen brings a significant increase in performance.

According to the invention, the object is achieved in that one or more years of balls provided as unbalance mass are that in a «RohrfOnalgen Oehluee, krelafOralgen Crosswise and any fora old compressed air can be applied

According to another Nerkaal of the invention, aa housing has a compressed air inlet opening and air inlet openings

With the use of a simple pipe * ale track and body, a simple and cheap method of making vibrators of this type is guaranteed. Duroh the arrangement of different curves of the oe-

housing results in operation of the invention Vibrators frequency jumps and acceleration sprays » the sloh e.g. when using the Znnenviforator for Compacting concrete, for example, has a beneficial effect on the Busseret material to be compacted. Ausserdeo takes place the excitement »e.g. in the development in the manner of a Helical springs in different levels »which, in turn, turns out to be very advantageous when compacting concrete, for example.

Advantageously, in the case of the vibrators according to the invention, they are conditionally connected to one another at will Curves of the housing "an alternating conversion of kinetic energy into potential energy and vice versa can be achieved" which also results in a significant increase in the performance of the devices according to the invention.

The embodiment of the vibrator according to the invention can be adapted at any time to the required conditions of use, since all shapes, such as the shape a circle »a helical spring» a safety pin etc. can be made.

Furthermore, the arrangement according to the invention enables a version as a portable device »since using compressed air cylinders they are under the most difficult Space and outdoor port conditions can be used »e.g. in the high mountains

The execution according to the invention is described in the following some execution examples explained in more detail »on the

The compressed air introduced into the housing 1 builds up calibrate a dew in front of the ball 4 so that the ball 4 rolls off in the housing 1. The frequency «with the the ball 4 rolls in the housing 1 is dependent on the air pressure and is therefore variable.

FIG. 2 shows a possibility of arranging several vibrators according to the invention in use as external vibrators on a base plate in order to to obtain certain centrifugal force.
