PNEUMATIC VIBRATOR (OPTIONS) Russian patent published in 2018 - IPC F15B21/12 

FIELD: machine building.

SUBSTANCE: group of inventions refers to vibration technology. Pneumatic vibrator according to the first embodiment includes upper and lower plates, a hammer placed between them, an adjusting nut, a supply valve with air inlet holes, the seat of which is mounted in the hammer, a membrane surrounding the outer surface of the valve seat of the feed, a seal fitted to the top plate, an exhausted exhaust air valve, fixed in the center of the seal and on the periphery of the impactor with the possibility of interaction with the surface of the hermetic and the impactor facing it. Lower plate, the supply valve and the diaphragm form a forward passage chamber, and the impactor and the exhaust valve are the return chamber. Adjusting nut is installed in the lower plate. Supply valve is installed in the adjusting nut with the possibility of free axial movement between its shoulders and the stop. In the device according to the second variant, the supply valve is made solid. Coaxial air supply channels are provided in the adjusting nut and the stop.

EFFECT: group of inventions is aimed at increasing the duration of action on the compressed air blower on the side of the forward motion chamber, eliminating the cyclic elastic deformations of the supply valve and ensuring the launch of the device when operating in low temperature conditions.
