HYDRAULIC SHOCK ABSORBING SYSTEM FOR IMPROVEMENT OF THE FORCES BALANCING AT THE OUTPUT Russian patent published in 2018 - IPC B62D12/02 

FIELD: machine building.

SUBSTANCE: invention relates to the hydraulic shock absorbing system. Hydraulic system contains the unidirectional pressure relief valve, the piston assembly and the cylinder assembly. Piston in assembly includes piston and the piston rod, and the cylinder in assembly comprises triple welded block and the cylinder. Piston in assembly is made inside the cylinder and divides the corresponding cylinder into the cavity with the rod and the cavity without rod. Unidirectional pressure relief valve with installed capacity contains spool. Spool divides the unidirectional pressure relief valve with the installed capacity into the first chamber, the second chamber and the third chamber. Spool is located inside the second chamber. Spool first end is connected to the first chamber, and the spool second end is connected to the third chamber. Second chamber contains the branch channel, and between the branch channel and the third chamber the reverse hydraulic communication opening is made. Unidirectional pressure relief valve is made inside the piston, and the first chamber is connected to the rod by cavity. Second chamber branch channel is connected to the rod by cavity.

EFFECT: enabling the balanced pressure provision at the hydraulic shock absorber output.
