Abstract
A magneto-rheological (MR) damper including a piston guided in a cylinder that is filled with a magneto-rheological fluid, its work volume being formed oblique relative to the piston axis between the piston and the cylinder.
Claims13
A magneto-rheological (MR) damper including a piston guided in a damper cavity of a cylinder that is filled with a magneto-rheological fluid, the rheological properties of which may be modified by application of a magnetic field;
- and
- wherein concurrently with a movement of the piston the fluid is pushed from a first work volume into a second work volume, and wherein each work volume is formed by an annular space extending obliquely relative to the piston axis between an outer cone surface of the piston and an inner cone surface of the cylinder, wherein by a movement of the piston the fluid flows from one annular space to the other annular space through a piston cavity which communicates with each annular space through at least one bore.
