Abstract
A compressed-air vibrator with a cylindrical housing confined between closure covers, within which there is arranged a piston reciprocated by the compressed air, whereby the compressed air is alternatingly introduced into the two working chambers through a central inlet groove in the cylinder bore and through axial bores which discharge through the end surfaces of the piston, and wherein the air is conveyed out of the chambers through outlets which are controlled by the piston edges.
Claims7
In a compressed-air vibrator including a cylinder housing having two longitudinal end surfaces each provided with a closure cover, a piston having two opposing ends each having a circumferential edge, reciprocated by said compressed air being arranged within a cylinder bore which is disposed within said housing;
- a central inlet groove in said cylinder bore;
- axial bores extending to the end surfaces of said piston;
- said compressed air being alternatingly conducted into two work chambers of said cylinder bore through said inlet groove and axial bores;
- and outlets in said work chambers for said compressed air controlled by the piston edges, the improvement comprising:
- said cylinder housing being a profiled member including four cross positioned ribs encompassing the central cylinder bore;
- four bores being arranged one each in said ribs and extending parallel to the axis of said cylinder bore;
- one said bore being an inlet bore for the infeed of compressed air, one said bore being an outlet bore for said compressed air;
- and fastening bolts being located in said remaining two bores.
