SHOCK ABSORBER Russian patent published in 2022 - IPC F16F9/508 F16F9/34 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. The valve seat element (106) is located in the cover element (101). In the chamber (20) on the other side is the first auxiliary valve (181). In the cover chamber (146) formed between the bottom section (122) of the cover element (101) and the valve seat element (106), there is a second auxiliary valve (171). In the second passage (182), there is an opening (175) on the inlet or outlet side from the first auxiliary valve (181) into the flow, with which the first auxiliary valve (181) is opened. In an area where the piston speed is low, the valve of the second damping force generating mechanism (183) opens in a state in which the valve of the first damping force generating mechanism (41) closes. In the velocity region in which the piston velocity is higher than the velocity in the region in which the piston velocity is low, both the valve of the first damping force generating mechanism (41) and the valve of the second damping force generating mechanism (183) are opened.

EFFECT: increase in the durability of the valve is achieved.
