Abstract
A shock-absorbing device includes an airtight cylindrical casing; at least one compressible springy ball arranged in the cylindrical casing; a main piston mounted in the cylindrical casing above the at least one compressible springy ball and reciprocated to compress the at least one compressible springy ball, the main piston having a piston rod extended out of the cylindrical casing; a damping substance flowing in the cylindrical casing; and a plurality of main piston valves respectively installed in said main piston for enabling the damping substance to flow between an upper chamber in the cylindrical casing above the main piston and a lower chamber in the cylindrical casing below the main piston.
Claims18
A shock-absorbing device comprising:
- a cylindrical casing defining an airtight space;
- at least a pair of compressible springy balls arranged in said cylindrical casing;
- a main piston mounted in said cylindrical casing above said at least a pair of compressible springy balls and dividing the airtight space of said cylindrical casing into an upper chamber and a lower chamber, said main piston being reciprocated to compress said at least a pair of compressible springy balls within said lower chamber, said main piston having a piston rod extending out of said cylindrical casing;
- a damping substance flowing in said cylindrical casing;
- a plurality of main piston valves respectively installed in said main piston for enabling said damping substance to flow between said upper chamber above said main piston and said lower chamber below said main piston;
- at lest one auxiliary piston position between said at least a pair of compressible springy balls;
- and,
- at least one auxiliary piston valve disposed in said at least one auxiliary piston for flow of said damping substance therethrough.
A shock-absorbing device comprising:
- a cylindrical casing defining an airtight space;
- at least one compressible springy ball arranged in said cylindrical casing;
- a main piston mounted in said cylindrical casing above said at least one compressible springy ball and dividing said airtight space of said cylindrical casing into an upper chamber and a lower chamber and reciprocated to compress said at least one compressible springy ball, said main piston having a piston rod extended out of said cylindrical casing;
- a damping substance filled in said cylindrical casing;
- a guide tube connected between top and bottom sides of said cylindrical casing and disposed outside said cylindrical casing and adapted to guide said damping substance between said upper chamber above said main piston and said lower chamber below said main piston;
- and
- a plurality of main piston valves respectively installed in said main piston for enabling said damping substance to flow between said upper chamber above said main piston and said lower chamber below said main piston through said guide tube.
