CYLINDER-PISTON UNIT WITH PISTON VALVE Russian patent published in 2017 - IPC F16F9/34 F16F9/19 E05F5/10 

FIELD: machine engineering.

SUBSTANCE: cylinder-piston unit (10) contains a cylinder (11) and a piston (61) having a longitudinal opening and guided in it by a piston rod (51). The piston (61) is sealed against the internal walls (12) of the cylinder and separates the displacement space (91) from the equalization space (92). There is one discharge piston (31) in the equalization (92) or displacement space (91). The discharge piston (31) is supported by a compression spring (33) and sealed against internal walls (12) of the cylinder. One disc valve together with the surface on the side of the displacement space limits the path. The path cross-sectional area, multiplied by the reciprocal length of the path and the reciprocal arithmetic mean deviation R_a of the bounding surface profile, is less than 50.

EFFECT: high damping and braking power.
