HANDLE OF PNEUMATIC MANUAL PERCUSSION ACTION MACHINE Russian patent published in 2005 - IPC

FIELD: manual percussion action pneumatic machines, particularly vibration-insulated handles, possibly used in building, machine engineering and other industry branches.

SUBSTANCE: handle of pneumatic percussion action machine includes housing in upper part of which air supply rod is mounted. In housing there is rod with piston embracing air supply rod with possibility of motion along it. Rod with piston divides cavity of housing to over-piston and under-piston chambers. Piston of rod has lengthwise duct for communicating over-piston and under-piston chambers of housing. There is radial opening in lateral surface of housing rod for cyclic communication of network of compressed air with over-piston chamber of housing cavity. In power part of housing stepped sleeve is fit at radial gap on rod with piston. In lateral surface of small step of said sleeve there is draining throttling opening designed for cyclic communication of over-piston chamber through lengthwise duct of piston with atmosphere. Stepped sleeve may be mounted in housing on shock absorber, for example on rubber shock absorber and it may perform restricted axial motion in range of elasticity of shock absorber.

EFFECT: enhanced operational safety due to locking shocks at handling machine from one cell to other in casting flask.
