PNEUMATIC DEVICE OF SHOCK ACTION FOR CREATION OF DRIVEN WELLS IN GROUND Russian patent published in 2008 - IPC E02F5/18 

FIELD: building.

SUBSTANCE: invention refers to the building techniques and can be applied to creation of a driven well in the ground. The device includes a hollow case with the stepless drummer placed in it with the central through channel dividing a hollowness of the case on the chambers of the worker and idling, a tube with the longitudinal channel, interacting with the central through channel of the drummer, threaded sleeve with constantly open inlet channel and a compressed air pipe from a network. It is supplied with a cover with the radial overflow channel and a through central aperture for passing the tube formed between the threaded sleeve and a cover by the prechamber of network air and a tang, entering into the idling chamber. The tang and the threaded sleeve are executed with through channels for passing the tube established in the central aperture of a cover with a ring clearance space, forming the throttle inlet channel in the operating stroke chamber, the exhaust channel which is executed under a sharp angle to an axis of a tube with vertex from the side of the threaded sleeve. The tube is fixed condensed against the tang the threaded sleeve.

EFFECT: provision of an outlet foul air stream orientation from chambers of the worker and idling, and also an increase of driven well making speed.
