Abstract
The present disclosure relates to a shock absorber, in more detail, a damping force controlling shock absorber of which a damping force characteristic can be appropriately adjusted. A damping force controlling shock absorber according to the present disclosure includes: a cylinder formed in a double structure of an inside and an outside, having an internal space divided into a compression chamber and a rebound chamber by a piston valve, and having a reservoir chamber in an external space; a compression solenoid valve mounted on the cylinder; a rebound solenoid valve mounted on the cylinder; and a check valve disposed in the rebound solenoid valve, and opening and closing a channel connecting the reservoir chamber and the rebound chamber.
Claims15
A damping force controlling shock absorber comprising:
- a cylinder formed in a double structure of an inside and an outside, having an internal space divided into a compression chamber and a rebound chamber by a piston valve, and having a reservoir chamber in an external space;
- a compression solenoid valve mounted on the cylinder;
- a rebound solenoid valve mounted on the cylinder;
- and
- a check valve disposed in the rebound solenoid valve, the check valve allowing for flow of fluid from the reservoir chamber to the rebound chamber and prevents flow of fluid in an opposite direction,
- wherein the rebound solenoid valve includes:
- a rebound valve housing that forms an external appearance of the rebound solenoid valve and in which fluid in the rebound chamber flows and circulates in a rebound stroke;
- and
- a rebound port disposed at an inlet of the rebound valve housing,
- wherein the check valve is installed between the rebound valve housing and the rebound port,
- wherein the rebound port includes:
- a rebound body having a hole therein and connected to the rebound chamber at a first end;
- a rebound flange extending outward from a second end of the rebound body and having a rebound hole connected to the reservoir chamber;
- and
- an annular protrusion protruding toward and contacting the rebound valve housing from the rebound flange, having an internal space therein and forming a space in which the check valve is installed.
A damping force controlling shock absorber comprising:
- a cylinder formed in a double structure of an inside and an outside, having an internal space divided into a compression chamber and a rebound chamber by a piston valve, and having a reservoir chamber in an external space;
- a compression solenoid valve mounted on the cylinder;
- a rebound solenoid valve mounted on the cylinder;
- and
- a check valve disposed in the rebound solenoid valve, the check valve allowing for flow of fluid from the reservoir chamber to the rebound chamber and prevents flow of fluid in an opposite direction,
- wherein, in a compression stroke, a portion of fluid in the compression chamber is sent to the reservoir chamber through the compression solenoid valve, and a portion of fluid in the reservoir chamber is sent to the rebound chamber due to opening of the check valve, and
- a portion of fluid in the rebound chamber is sent to the compression chamber through the rebound solenoid valve and the compression solenoid valve in a rebound stroke,
- wherein the rebound solenoid valve includes:
- a rebound valve housing that forms an external appearance of the rebound solenoid valve and in which fluid in the rebound chamber flows and circulates in a rebound stroke;
- and
- a rebound port disposed at an inlet of the rebound valve housing,
- wherein the check valve is installed between the rebound valve housing and the rebound port,
- wherein the rebound port includes:
- a rebound body having a hole therein and connected to the rebound chamber at a first end;
- a rebound flange extending outward from a second end of the rebound body and having a rebound hole connected to the reservoir chamber;
- and
- an annular protrusion protruding toward the rebound valve housing from the rebound flange, having an internal space therein and forming a space in which the check valve is installed.
