that is, to achieve maximum effectiveness in terms of generating vibrations and thereby nevertheless the chambers 14 and 15 into which the pressurized fluid enters are as small as

A rectangular plate 9 can move radially in a slot II which connects the channel 7 with the bore of the outer cylinder 1. The dimensions are chosen so that the plate rest with its outer edge on the cylindrical surface of the intermediate cylinder 3 or can retract completely into the wall of the outer cylinder 1 when the intermediate cylinder 3, the

However, the pressurized flow medium enters the working chamber instead of through the outer cylinder through a channel la in the inner cylinder and radial bores 8a and exits again via openings \ 2a in the flanges 4a and 5a firmly connected to the inner cylinder la. The flanges 4a and 4a Sa are in contact with the shoulders 10 of the outer cylinder 1 «.

With such a construction of the vibrator, large eccentricity between the inner and outer, it is possible to ensure a cylinder given by the distance QG 2 and to realize the volume of the flow eccentricity which is as large as reducing medium working chambers to which it is the inner and the outer cylinder allow, ie 60 equal results.
