VIBRATOR Russian patent published in 2020 - IPC F15B21/12 B06B1/18 

FIELD: machine building.

SUBSTANCE: invention relates to a vibration technique. Vibrating vibrator unit is loaded by means of cover 10 of support plate 4 by springs 54 located in seats 53 of disk-like support element 16. Valve pair is located on the vibrating unit. Valve 34 is spring-loaded with support on valve bushing 22 and contacts with seat 56 of holes 55 made in sockets 53.
